18 kg Gas Bottle Dimensions: Complete Specifications for B2B Buyers (2026 Guide)
Meta Description: Get the exact 18 kg gas bottle dimensions including height, diameter, tare weight, valve type, and filling specs. Trusted factory-direct supplier with ISO 9001, CE, and COA. OEM/ODM available. FOB China.
If you are sourcing 18 kg gas bottle dimensions for your next bulk order, here are the industry-standard specifications you need: a typical 18 kg LPG or N₂O cylinder measures approximately 820–870 mm in height (without valve), 240–260 mm in outer diameter, with a tare weight of 16.5–19.0 kg depending on the steel grade and valve configuration. At Zhuzhou XingYe Chemical, we manufacture and supply high-pressure steel cylinders that precisely meet these dimensional standards, compliant with DOT, ISO 9809, and EC directives. Whether you are a brand owner or sourcing agent, understanding these exact measurements is critical for packaging, freight optimization, and end-user safety.
The Real Challenge When Sourcing 18 kg Gas Cylinders
Import managers and wholesalers frequently encounter three pain points:
- Inconsistent dimensions – Cylinders from different factories vary in height and diameter, causing container loading inefficiency and logistics disputes.
- Certification gaps – Many suppliers lack third-party compliance for the US market (DOT-SP, TC, ISO 9809), leading to customs holds.
- Unreliable lead times – Without in-house production control, delays of 30–60 days are common.
Our solution: As a 10+ year factory with ISO 9001, CE, and ECM certification, we deliver cylinders with guaranteed dimensional consistency, full compliance documentation (COA, MSDS, Food-Grade certificates), and 15–25 day lead time for standard 18 kg bottles. Every batch is tested to 250 bar hydrostatic pressure before dispatch.

⭐ What Our Global Buyers Say
Beverage Equipment Distributor, Florida, USA
"We have purchased over 3,000 units of the 18 kg CO₂ bottles from XingYe across six shipments. The dimensions are perfectly consistent – every cylinder fits our filling manifold without adapters. The COA documentation is always in order for our FDA audits. Lead times have been reliable at 18–22 days."
N₂O Cream Charger Brand, Melbourne, Australia
"We needed a custom orange RAL 2011 finish with our private label on 18 kg N₂O bottles. The OEM team at XingYe matched the color perfectly on the first sample. The 18 kg dimensions (845 mm height, 245 mm diameter) fit our pallet design exactly. High-quality steel and valve – zero leaks in 12 months."
Gas Equipment Procurement, Dubai, UAE
"I sourced 18 kg gas bottles from three different Chinese factories. XingYe was the only one that delivered the exact tare weight (±0.3 kg) as stated on the specification sheet. The other suppliers had 1–2 kg variation. This matters for our freight calculation and end-customer billing. Highly recommended for accuracy."
Industrial Gas Distributor, Texas, USA
"We run a multi-gas distribution center. The 18 kg argon/CO₂ mix cylinders from XingYe are our best-selling SKU. The consistent dimensions (910 mm with valve) stack perfectly in our warehouse racks. Hydro test certification and DOT-SP paperwork were all in order. Will continue to reorder."
