A 5KG LPG cylinder is designed to hold approximately 5 kilograms of liquefied petroleum gas when filled according to the applicable filling requirements. In common commercial designs, its body diameter is often around 300–320 mm, while its overall height may be approximately 400–500 mm, depending on the valve, collar, foot ring, and handle arrangement. The empty cylinder commonly weighs about 5–7 kg, so the filled operating weight may be approximately 10–12 kg. These figures are practical reference ranges rather than universal specifications, because dimensions and tare weight vary by country, cylinder standard, material, and manufacturer.

When I describe a cylinder as a 5KG LPG cylinder, I am referring to its nominal LPG filling capacity. This means the cylinder is intended to contain approximately 5 kg of LPG under the filling conditions permitted by the relevant local rules. It does not mean that the complete cylinder, including the steel body and valve, weighs only 5 kg.
The complete filled weight consists of three main elements: the empty cylinder, the LPG inside, and the valve or other attached components. For example, an empty cylinder with a 6 kg tare weight would weigh approximately 11 kg when filled with 5 kg of LPG. The actual result may be slightly different because of manufacturing tolerances, valve configuration, residual gas, and filling practice.
The dimensions of a 5KG LPG cylinder are not identical across all markets. A standard steel cylinder may have a body diameter of approximately 300–320 mm and an overall height of around 400–500 mm. However, the total height can change when the design includes a protective collar, integrated handle, larger foot ring, or a different valve guard.
For logistics planning, I suggest treating these figures as preliminary space requirements rather than final packaging data. A buyer should request the supplier’s approved dimensional drawing before designing a rack, cabinet, pallet, vehicle compartment, or retail package. The drawing should distinguish body height from total height and should identify the maximum diameter at the widest point.
The empty weight of a 5KG steel LPG cylinder is commonly around 5–7 kg, although the range can be wider depending on the steel thickness, design pressure, accessories, and applicable manufacturing standard. The precise empty weight is known as the tare weight, and it is normally marked on the cylinder or recorded in the production documentation. I recommend using the marked tare weight instead of estimating the shipping weight.
When the cylinder contains 5 kg of LPG, the filled weight is generally the tare weight plus the gas weight. Therefore, a cylinder with a 5.5 kg tare weight would have an approximate filled weight of 10.5 kg before accounting for small variations. This calculation is useful for manual handling, delivery planning, pallet loading, and transport cost estimates.
For commercial orders, I encourage buyers to separate three weight questions: the nominal LPG capacity, the average tare weight, and the maximum gross weight. These figures serve different purposes and should not be combined in a single product description. If the cylinder will be handled frequently by consumers, a lower tare weight may improve portability, but it must still meet the required safety and mechanical specifications.
The nominal LPG capacity of this product is approximately 5 kg. A cylinder also has a water capacity, which is the internal volume measured using water and is used as a design reference. Water capacity is not the same as the mass of LPG that the cylinder can safely contain.
Liquefied petroleum gas expands as temperature increases, so LPG cylinders are not normally filled completely to the internal volume. A commonly used filling limit is approximately 80% of the cylinder’s water volume, but the exact requirement depends on the gas type, local regulation, cylinder standard, and filling procedure. For this reason, I do not recommend calculating the approved LPG fill weight from dimensions alone.
A buyer may see a water capacity listed in litres and mistakenly assume that it represents the LPG quantity in kilograms. The two measurements use different concepts: water capacity describes internal volume, while LPG capacity describes the permitted mass of gas. The supplier should provide the nominal LPG capacity, water capacity where required, tare weight, test information, and marking details as separate technical items.

| Specification | Typical Reference for a 5KG Cylinder | Buyer Note |
|---|---|---|
| Nominal LPG capacity | Approximately 5 kg | Confirm the permitted filling mass for the target market. |
| Body diameter | Approximately 300–320 mm | Confirm the maximum external diameter with accessories. |
| Overall height | Approximately 400–500 mm | Measure from the base to the highest protective component. |
| Empty tare weight | Approximately 5–7 kg | Use the marked or documented production value. |
| Filled operating weight | Approximately 10–12 kg | Calculate using actual tare weight plus LPG weight. |
A 5KG LPG cylinder is often selected where users need a compact gas supply for cooking, small food-service operations, outdoor activities, temporary work areas, or household backup use. Its smaller format can be easier to move than a larger cylinder, although the filled weight still requires safe lifting and stable placement. The best application depends on local gas consumption, refill availability, regulator compatibility, and storage requirements.
For a restaurant or commercial kitchen, I recommend calculating expected daily consumption before choosing the cylinder size. A smaller cylinder may be convenient for limited or intermittent use but could require more frequent replacement in a high-consumption environment. For distributors, the decision should also include pallet efficiency, return logistics, retail handling, and the availability of compatible valves in the destination market.
Most conventional 5KG LPG cylinders are made from steel because steel provides a familiar balance of strength, availability, and cost. Steel designs can be supplied with different surface treatments, including painted or coated finishes, subject to the customer’s market and technical requirements. The appropriate finish should be selected for the storage environment, handling conditions, appearance, and maintenance expectations.
Some markets also use lightweight or composite cylinder concepts. These options may reduce handling weight, but their purchase cost, approval requirements, valve design, supply chain, and service procedures can differ substantially from standard steel products. I recommend comparing the complete lifecycle requirements rather than selecting a cylinder only by empty weight.
First, I identify the destination country, intended gas type, applicable cylinder standard, marking language, and required valve connection. A cylinder that fits physically may still be unsuitable if its valve, markings, test requirements, or documentation do not match the destination market. These details should be agreed before production rather than after shipment.
Next, I compare the approved drawing with the customer’s available space and handling equipment. The technical file should clearly state dimensions, tolerance, tare weight, nominal capacity, material, wall thickness where applicable, valve specification, and surface treatment. If the product will be stacked or palletized, I also confirm the package dimensions and gross shipping weight.
A 5KG cylinder should remain stable during storage, transport, and use. Buyers should consider the foot ring, protective collar, handle design, valve protection, label position, and compatibility with the intended regulator. For manual handling, I also recommend checking whether the filled weight is appropriate for the users and delivery process.
At Shuofang, I approach a 5KG LPG cylinder project as a specification-matching exercise rather than a one-size-fits-all product sale. We can discuss the target market, required capacity, valve configuration, dimensions, tare-weight expectations, finish, markings, packaging, and export documentation before confirming an order. This helps reduce the risk of receiving cylinders that do not fit your filling, distribution, or end-use system.
For an accurate quotation, I recommend sending the destination market, estimated order quantity, preferred valve, required color or marking, packaging method, and any existing technical drawing. If you do not yet have a finalized specification, we can help organize the main parameters for review. Final dimensions, weight, and capacity should always be confirmed in the approved product documentation before mass production.
A typical 5KG LPG cylinder holds approximately 5 kg of LPG, has an overall height of about 400–500 mm, a body diameter of around 300–320 mm, and an empty tare weight of approximately 5–7 kg. Its filled operating weight is commonly about 10–12 kg, but the exact figures depend on the design, valve, protective components, and applicable standard. These ranges are suitable for early planning, not for replacing a manufacturer’s approved specification.
My recommended next step is to request a technical drawing and product data sheet that clearly separates nominal LPG capacity, water capacity, tare weight, gross filled weight, and external dimensions. Then verify valve compatibility, local requirements, packaging, and handling conditions before placing the order. If you are sourcing a 5KG LPG cylinder for distribution, household use, food service, or export, Shuofang can review your requirements and prepare a specification-based quotation for your project.
