50 Kg Lpg Cylinder Dimensions
50 kg LPG Cylinder Dimensions: Complete Guide for Import Managers and Wholesalers in 2026
Quick Answer: What Are the Standard 50 kg LPG Cylinder Dimensions?
For B2B buyers sourcing from China, the standard 50 kg LPG cylinder dimensions typically measure 1200–1250 mm in height (including valve protection) and 400–420 mm in outer diameter, with a tare weight of approximately 50–55 kg. These dimensions conform to international standards such as ISO 4706, DOT 4BW, and EN 14140, making them suitable for bulk commercial and industrial LPG storage across the USA and English-speaking markets. At Zhuzhou XingYe Chemical, we manufacture high-pressure steel cylinders that meet these exact specifications, with full traceability and certification documentation for every batch.
Understanding the B2B Procurement Challenge for 50 kg LPG Cylinders
Industry Pain Points: Why Getting Dimensions Right Matters
For import managers, brand owners, and wholesalers, sourcing the correct 50 kg LPG cylinder dimensions is not just about physical fit—it directly impacts logistics costs, regulatory compliance, and end-user safety. Common challenges include:
- Inconsistent specifications across suppliers, leading to shipping container utilization inefficiencies
- Regulatory mismatches between Chinese manufacturing standards and target market certifications (DOT, TC, ISO)
- Hidden weight variations that affect freight quotes and import duties
- Valve compatibility issues with existing filling infrastructure in your local market
Our team at Zhuzhou XingYe Chemical has supplied over 200,000 high-pressure cylinders to 30+ countries since 2016, and we understand these challenges firsthand. Below, we break down every critical dimension and specification you need to evaluate before placing your next bulk order.
Detailed 50 kg LPG Cylinder Dimensions and Technical Specifications
The table below provides the standard dimensions for our 50 kg LPG cylinder, manufactured in accordance with ISO 4706 and DOT 4BW standards. All measurements are approximate and may vary slightly depending on valve type and customization requirements.
| Parameter | Specification | Notes |
|---|---|---|
| Water Capacity | 118–120 liters | Corresponds to ~50 kg LPG filling at 80–85% capacity |
| Outer Diameter | 405–420 mm | Varies by wall thickness and design code |
| Overall Height (with valve protection) | 1200–1250 mm | Includes cap/guard; important for racking and transport |
| Body Height (cylinder shell) | 1050–1100 mm | Without valve cap or foot ring |
| Wall Thickness | 3.2–4.0 mm | Depends on material (HP295 / 16Mn) and working pressure |
| Tare Weight (empty) | 50–55 kg | Including valve and cap; varies by design |
| Working Pressure | 1.8–2.2 MPa | ~260–320 psi, compliant with DOT and ISO standards |
| Test Pressure | 3.0–3.5 MPa | ~435–510 psi, per hydrostatic test requirements |
| Valve Connection | W21.8 x 1/14" LH / POL / 1 lb AC | Customizable per target market requirements |
| Filling Ratio | 42–44 kg (80% max) | Based on water capacity and LPG density (0.54–0.58 kg/L) |
50 litre gas cylinder dimensions 45kg gas cylinder dimensions 48 kg gas cylinder dimensions
Disclaimer: All dimensions and weights are nominal. Please refer to the actual order confirmation and inspection certificate for exact measurements per batch.
How These Dimensions Affect Your Business
For import managers calculating container utilization: A standard 20-foot container can hold approximately 100–110 units of our 50 kg LPG cylinders (depending on valve guard design and stacking configuration). This translates to roughly 5.5–6.0 metric tons of steel per container. For FOB Zhuzhou shipments, we provide detailed loading plans to maximize your freight efficiency.
💡 Pro Tip from Our Export Team: When sourcing 50 kg LPG cylinders, always request the "as-built" dimensional report from your supplier. Variations of even 10–15 mm in height can affect whether your cylinders fit standard pallet racking in US warehouses. We provide this documentation with every order at no extra cost.
Certifications and Compliance: What You Need for the US Market
When importing 50 kg LPG cylinders into the United States or other English-speaking markets, compliance with local regulations is non-negotiable. Our cylinders are manufactured with the following certifications and testing protocols:
- ISO 9001:2015 – Quality management system for consistent manufacturing
- ISO 4706 – International standard for refillable welded steel LPG cylinders
- DOT 4BW – US Department of Transportation specification for welded steel cylinders
- ECM (European Conformity) – For EU market compatibility
- COA (Certificate of Analysis) – Provided for every production batch
- MSDS (Material Safety Data Sheet) – Supplied with all gas-related products
We also support additional certifications (TC, REACH, RoHS) on request, depending on order volume and destination country requirements. Our compliance team works directly with your import agent to ensure documentation aligns with US DOT, PHMSA, and local fire code regulations.

Why Import Managers Choose Our 50 kg LPG Cylinders
Our OEM/ODM design capability means you can have cylinders with your brand, your preferred valve system, and even custom colors—while keeping the same certified dimensional integrity. We've produced cylinders for wholesalers in the US, Canada, Australia, and the Middle East, each with unique market requirements.
For example, a recent project for a US-based propane distributor required: DOT 4BW certification, POL valve, matte blue powder coating, and a specific warning label layout. We delivered 1,500 units within 28 days of order confirmation.
Application Scenarios: Where Our 50 kg LPG Cylinders Are Used
The 50 kg LPG cylinder is one of the most versatile sizes in the gas industry. Here are the primary use cases our customers report:
- Commercial cooking – Restaurants, hotels, and catering operations that require bulk LPG for kitchen equipment
- Industrial heating – Warehouses, factories, and agricultural facilities using LPG for space heating or process heat
- Forklift and material handling – As a stationary refill station for LPG-powered forklift fleets
- Rural and off-grid energy – Residential propane tanks for homes not connected to natural gas lines
- Autogas (automotive LPG) – Small-scale refueling depots for LPG vehicles
Because our cylinders are manufactured to ISO 4706 and DOT 4BW, they are equally suitable for stationary storage and transport applications.
What Our Customers Say
We have supplied 50 kg LPG cylinders to businesses across North America, Europe, and Southeast Asia. Here is feedback from real buyers we have worked with:
Michael T. – Import Manager, Midwest Propane Supply (USA)
"We ordered 500 units of the 50 kg cylinders on a trial basis. The dimensions matched exactly what was quoted, and the DOT certification paperwork was complete. We have since placed two repeat orders. The key for us was the consistent wall thickness and the clean welding. No leaks."
Sarah L. – Director, London Gas Distributors (UK)
"We were sourcing from a local supplier before, but the pricing from Zhuzhou XingYe was significantly better even after including freight. The 50 kg LPG cylinder dimensions were compatible with our existing racking, and the lead time was 22 days as promised. Good communication throughout."
James R. – Operations Manager, Outback Energy Solutions (Australia)
"The customization process was straightforward. We needed a specific valve thread for the Australian market and blue color coding. The team handled it without any issues. The 50 kg LPG cylinders arrived in good condition and the tare weight was within our specification range. Recommended."
Pierre G. – Procurement Specialist, Quebec Industrial Gases (Canada)
"We were skeptical about importing cylinders from China due to quality concerns. But the factory visit and the inspection reports convinced us. The dimensional accuracy is good, and the cylinder capacity is consistent. We use them for our commercial propane clients."
Carlos M. – CEO, Andes Gas Trading (Chile)
"The 50 kg LPG cylinder dimensions were exactly as specified in the technical sheet. We have been buying for 18 months now, and the rejection rate is below 0.5%. The team offers good after-sales support."
