If you are sourcing 8.5 kg gas bottles for LPG, propane, butane, or specialty gases like N₂O, knowing the exact 8.5 kg gas bottle dimensions is critical for logistics, storage, and end-user compatibility. A standard 8.5 kg LPG cylinder typically measures 300 mm (11.8 inches) in diameter by 460 mm (18.1 inches) in height, with a tare weight of approximately 7.5 kg. At Zhuzhou XingYe Chemical, we manufacture these high-pressure steel cylinders to rigorous international standards, ensuring dimensional consistency across every batch. Whether you are an import manager or a brand owner, this guide covers everything you need to know to make an informed procurement decision.
1. Standard 8.5 kg Gas Bottle Dimensions & Technical Specifications

The 8.5 kg cylinder is one of the most widely used sizes globally for residential, commercial, and industrial applications. Below are the standard parameters. Note: Exact specifications may vary slightly by manufacturer and gas service type. Zhuzhou XingYe provides certified drawings upon order confirmation.
| Parameter | Metric (mm / kg) | Imperial (inches / lbs) | Tolerance |
|---|---|---|---|
| Outer Diameter | 300 mm | 11.8 in | ± 2.0 mm |
| Overall Height | 460 mm | 18.1 in | ± 3.0 mm |
| Tare Weight | ~ 7.5 kg | ~ 16.5 lbs | ± 0.5 kg |
| Water Capacity | ~ 19.8 L | ~ 5.2 Gal | ± 0.2 L |
| Wall Thickness | 2.5 - 3.0 mm | 0.098 - 0.118 in | Per design spec |
| Working Pressure (LPG) | 1.8 MPa | 261 PSI | Standard |
2. Why Precise Dimensions Matter in B2B Sourcing
In B2B procurement, a few millimeters can make a significant difference in your bottom line. Here’s why the standard 8.5 kg gas bottle measurements are critical:
- Container Optimization: A standard 8.5 kg cylinder (300 mm diameter) fits efficiently in standard 20GP and 40HQ containers. For example, a standard pallet (1.2 m x 1.0 m) can hold exactly 9 cylinders per layer in a 3x3 configuration. This predictable loading reduces shipping costs per unit.
- Regulatory Compliance: Whether you need DOT (USA), TPED (EU), AS (Australia), or TC (Canada) certified cylinders, dimensional compliance is mandatory. Non-standard dimensions can lead to customs delays and fines. Zhuzhou XingYe Chemical manufactures to these exact global standards.
- End-User Compatibility: Most BBQ cabinets, forklift brackets, and gas heater compartments are designed around the standard 11.8-inch diameter and 18.1-inch height. Providing a perfectly dimensioned bottle ensures hassle-free adoption for your customers.
- Brand Consistency: For OEM/ODM buyers, cylinder dimensions directly impact packaging design, labeling placement, and overall brand presentation. Dimensional consistency reinforces product quality perception.
3. Application Scenarios for the 8.5 kg Cylinder
Understanding where these bottles are used helps align product specs with market demand. The 8.5 kg size is a versatile workhorse.
| Industry / Application | Gas Type | Specific Needs |
|---|---|---|
| Residential BBQ & Heating | LPG / Propane / Butane | Standard dimensions, rust-resistant paint, ergonomic handle, Clip-on / ACME valve. |
| Commercial Catering | LPG / Propane | Consistent tare weight for exchange programs, robust valve protection. |
| Industrial / Forklift | LPG / Propane | Heavy-duty base ring, fixed liquid level gauge, POL valve. |
| Specialty Gases (N₂O, CO₂, O₂) | Nitrous Oxide / Carbon Dioxide / Oxygen | High-purity internal treatment, specific valve connections (CGA, Pin-Index), higher working pressure options (up to 20 MPa). |
