When you're trying to fit a 5 kg gas cylinder into a specific space—be it a transport rack, a lab setup, or a cryogenic storage unit—knowing the exact Gasflasche 5 kg Maße, or dimensions, is absolutely essential. Getting this wrong can lead to serious compatibility headaches and delays.
A standard 5 kg steel propane cylinder typically stands 47.5 cm high with its protective cap on and has a diameter of 22.9 cm. While these figures are largely standardised, you'll find slight variations between manufacturers, which is why double-checking is always a good idea. These measurements are the key to handling everything from logistics and storage planning to operational safety.
For anyone working in biobanking, labs, or industrial fields, having gas cylinder specs on hand is part of the job. You need to know if that cylinder will fit before it arrives. This is all about preventing those frustrating and expensive moments when you realise a piece of equipment doesn't match its intended space.
Here’s a quick lookup table with the essential specs for a typical 5 kg steel gas cylinder you'd find in Germany.
| Specification | Measurement (cm/kg) | Notes |
|---|---|---|
| Height (with cap) | 47.5 cm | This is the full height needed for clearance. |
| Height (without cap) | 46.0 cm | Relevant for connection and valve clearance. |
| Diameter | 22.9 cm | The widest point of the cylinder's body. |
| Tare Weight (Empty) | ~5.8 kg | Varies slightly by manufacturer. |
| Full Weight (with Propane) | ~10.8 kg | Important for transport and handling safety. |
This table gives you the at-a-glance numbers you need for most planning purposes. Remember, the tare weight can differ, so always check the stamped marking on the cylinder itself for the most accurate empty weight.
The image below gives you a clear visual breakdown of these core measurements.
As you can see, the height and diameter are what you need for spatial planning, while the weight is crucial for safe handling and transport. Although these dimensions are quite consistent across the industry, it never hurts to confirm the exact measurements with your supplier if your setup has tight tolerances.

When you're working with 5 kg gas cylinders, understanding the Gasflasche 5 kg Maße (5 kg gas cylinder dimensions) is about more than just numbers on a spec sheet. It's about practical compatibility. The common standard dimensions—a height of roughly 47.5 cm and a diameter of 22.9 cm—aren't arbitrary.
These measurements ensure that a cylinder will slot correctly into a whole host of equipment. Think of everything from purpose-built transport racks and safety storage cabinets to the incredibly tight confines of a cryogenic freezer in a lab or biobank. A few millimetres of difference can be all it takes to make a cylinder unusable for its specific task.
It's important to remember, though, that manufacturing tolerances are a reality. While 22.9 cm is the industry-standard diameter, you can find slight variations between manufacturers and even different production runs. If you're planning an installation with zero room to spare, it's always best practice to measure the physical space yourself and then double-check the exact cylinder dimensions with your supplier before ordering.
The material a cylinder is made from introduces another variable, mainly impacting its weight but sometimes its dimensions in subtle ways.
The most noticeable difference you'll find is the tare weight. A lighter aluminium cylinder is simply easier to manage and helps reduce the overall payload weight during transport. This can be a critical benefit when operating under ADR regulations for the transport of dangerous goods.
This overview is a great illustration of the consistency you find across cylinder types and their components, which all share a standardised form.
The design consistency, from the protective valve cap down to the foot ring at the base, is what guarantees stability and allows for secure mounting. In the end, deciding between steel and aluminium comes down to balancing your need for durability and low cost against the benefits of portability.
When you're dealing with the dimensions of a 5 kg gas cylinder, or "Gasflasche 5 kg Maße," the physical measurements are just one piece of the puzzle. The standards and regulations behind that cylinder are what truly guarantee its safety and reliability, especially in demanding cryogenic or industrial settings.
These aren't just bureaucratic formalities. They are the essential framework ensuring that a cylinder from any manufacturer will be safe, robust, and compatible with your equipment.
The foundational standard for the cylinder's actual construction is DIN EN 13110. This regulation sets out the requirements for transportable, refillable welded steel cylinders. It’s why you can trust that the basic structure is sound and will fit into standardised mounting brackets or storage cabinets.
For anyone connecting these cylinders to equipment, the valve standards are absolutely critical. EN ISO 15995, for instance, specifies the design of cylinder valves. This ensures they can handle the necessary pressure and will mate correctly with standard pressure reducers, preventing dangerous mismatches when hooking up to sensitive equipment like a cryogenic freezer.
Beyond the physical design, the most important regulation is the Pressure Equipment Directive (PED 2014/68/EU). This is an EU-wide directive that dictates the safety requirements for all pressure equipment, gas cylinders included. It forces manufacturers to design and test cylinders to withstand pressures far greater than what they'll see in normal use.
A key part of this is the test pressure. A standard 5 kg steel cylinder is typically subjected to a 30-bar test pressure. This is much higher than the internal pressure of propane gas at normal temperatures. This intense testing, often certified by a notified body like TÜV, confirms the cylinder's structural integrity. It's your assurance that it can handle unexpected temperature spikes safely.
The 5 kg gas cylinder became widespread in Germany after the 1990s, with its design evolving to meet these stringent standards. Early steel bottles were updated to comply with DIN EN 13110 and the EU Pressure Equipment Directive 2014/68/EU, featuring nominal wall thicknesses of 3.21-3.61 mm and a 30 bar test pressure certified by TÜV-SÜD. You can find more on the history and safety evolution of these cylinders at gasflasche.de. This history really highlights how these regulations have created an incredibly reliable and safe product for critical applications.
Knowing the Gasflasche 5 kg Maße gets you halfway there, but true compatibility hinges on the valve and its connection. If you're working with a 5 kg propane cylinder in Germany, you'll almost certainly encounter the W 21.8 x 1/14 LH thread, which is standardised under EN 15202. This isn't just a random set of numbers; it's the key to correctly fitting everything from pressure reducers for industrial gas lines to specialised cryogenic systems.
The "LH" in that code is crucial—it stands for "left-hand thread." This is a fundamental safety design. By industry convention, combustible gases like propane use left-hand threads. Why? To make it physically impossible to accidentally screw on equipment meant for non-combustible gases (like nitrogen or oxygen), which use standard right-hand threads. It’s a simple, mechanical safeguard against a potentially dangerous mix-up.
A good way to remember this in the field is that for most things, it's "righty-tighty." But for flammable gases, you have to think backwards: it's "lefty-tighty." This counter-intuitive direction is a deliberate safety feature.
Attaching a pressure reducer seems like a basic task, but getting it right is non-negotiable for ensuring a leak-free seal and steady gas flow. I've seen cases where a connection seems to fit, like a German regulator on some French bottles, but the threads aren't identical and the connection will leak under pressure.
Always follow these steps for a secure connection:
This procedure is the same whether you're hooking up a barbecue or plumbing a supply line to sensitive lab equipment. Of course, the valve itself needs care when not in use. You can learn more about the important role of a protective cap for gas cylinders in our related article.
When you're handling a 5 kg gas cylinder, you'll notice a few terms stamped on its collar that can seem a bit confusing at first. Getting to grips with the difference between tare weight, full weight, and filling capacity is absolutely crucial, not just for safety but for practical day-to-day use. It's the only real way to know how much gas you've got left.
Let's start with the easiest one: the filling capacity. This is simply the net weight of the gas that the cylinder is certified to hold safely. For a standard 5 kg gas bottle, this is exactly 5 kg of propane or a similar liquefied gas. It’s important to realise this refers to the weight of the gas, not its volume, which can fluctuate quite a bit with changes in temperature and pressure.
Next up is the tare weight, which you'll often see stamped as "TARA" on the cylinder's collar. This is the weight of the empty bottle itself, including the valve but not the plastic protective cap. A typical steel 5 kg gas bottle has a tare weight of around 5.8 kg, though you'll find this can vary a little from one manufacturer to another based on slight differences in construction.
You must always check the specific tare weight stamped on the individual cylinder you are using. Relying on an average figure can lead to inaccurate measurements and serious safety risks, like overfilling or misjudging your remaining supply.
The full weight, also known as the gross weight, is just the sum of the tare weight and the filling capacity.
This simple bit of maths is vital for checking you've received a full cylinder from your supplier and for any transport logistics. For instance, if you're planning any ADR-compliant transport, you'll need the total gross weight of all cylinders to calculate your payload correctly. The same principle applies to lighter aluminium cylinders; they just have a lower tare weight, which in turn reduces the full weight and makes them a great choice for mobile applications like cryo-logistics where every kilogram matters.
Moving gas cylinders, even the smaller 5 kg models, isn't something you can take lightly. The whole process is governed by a strict set of international rules known as the Accord Dangereux Routier (ADR). These regulations cover the road transport of dangerous goods across borders, making sure everything from industrial gases to critical materials for biobanks are handled safely.
This is where the standardised Gasflasche 5 kg Maße become so important. Their consistent dimensions are what allow for the design and use of certified transport pallets and racks. These systems ensure cylinders are kept upright and completely secure during transit, which is absolutely non-negotiable. An unsecured cylinder can easily turn into a dangerous projectile in the event of an accident.
On top of that, the ADR lays out very specific labelling rules. Every cylinder must be clearly marked according to CLP regulations (Classification, Labelling and Packaging), complete with hazard pictograms and information on its contents. This labelling is vital for emergency services, as it allows them to immediately identify the risks involved if an incident occurs.
Properly securing your cylinders is the absolute bedrock of ADR compliance. It’s not as simple as just putting them in the back of a vehicle. They must be fastened down in a way that prevents any and all movement, tipping, or impact for the entire journey.
For places like universities, hospitals, and pharmaceutical firms, the most straightforward solution is often to work with an ADR-licensed logistics provider. They already have the certified equipment and deep expertise to guarantee full compliance. If you're tackling this yourself, you can find more detailed guidance in our article on the safe transport of gas cylinders.
Expert Insight: In our experience, the single most common ADR violation we see with smaller operations is improper securing. A simple ratchet strap just won’t cut it. Regulators expect to see purpose-built solutions that perfectly match the cylinder’s dimensions and weight, leaving absolutely no chance for movement.
When you're dealing with gas cylinders, especially where a precise fit and absolute safety are required, questions are bound to come up. We've gathered the most common queries about Gasflasche 5 kg Maße (5 kg gas cylinder dimensions) and other practical details to give you clear, straightforward answers.
This information is designed to help you choose the right cylinder, whether it's for a cryogenic system, a lab setup, or a portable BBQ. Getting these details right from the start is the key to ensuring both compatibility and safety.
No, definitely not. While the physical Maße (dimensions) of 5 kg cylinders are quite standard among manufacturers, compatibility involves much more than just size. The most important things to check are the gas type, the valve connection, and the cylinder’s pressure rating. For instance, a propane cylinder in Germany has a left-hand thread (W 21.8 x 1/14 LH) for a reason—it physically stops you from connecting it to equipment meant for non-flammable gases like oxygen.
Hooking up a cylinder with the wrong gas or an incorrect valve can cause dangerous leaks, damage your equipment, or simply not work at all. Always double-check your equipment's manual and confirm with your gas supplier that the cylinder's specs are a perfect match for your system.
Practical Example: You might find that a German propane cylinder seems to connect to certain French equipment because the threads feel similar. They are not identical. That connection will almost certainly leak under pressure, creating a major safety risk. Always use the proper, region-specific adaptors if you have to mix and match.
In Germany, the colour of a 5 kg propane cylinder isn't about the gas inside or its dimensions—their Maße are identical. Instead, the colour tells you about the ownership model.
The choice really comes down to cost and convenience. If you use gas often and have easy access to different filling stations, a grey property bottle usually works out to be more economical over time. For more sporadic use, the red deposit system can be a lot simpler.
Because propane is stored as a liquid, a pressure gauge won't give you an accurate reading. The pressure stays fairly constant right up until the point the cylinder is almost empty. The only reliable way to know how much gas you have left is to weigh the cylinder.
First, find the tare weight, which is the weight of the empty cylinder. This is usually stamped on the collar or shoulder, often marked as "TARA" or "TW". Then, put your current cylinder on a bathroom or luggage scale to get its total weight.
To calculate the remaining gas, just subtract the tare weight from the total weight you just measured.
Generally, yes. The external physical dimensions (Maße) of the 5 kg steel cylinder shell itself are standardised, so the height and diameter will be the same whether it's filled with propane, nitrogen, or argon.
However, that's where the similarities end. Everything else—the valve type, the pressure rating, and especially the colour-coding and safety labels—will be completely different depending on the gas inside. Never, under any circumstance, attempt to use a cylinder for a gas it wasn't designed and certified for. Doing so is incredibly dangerous and also illegal.
