2 kg Gas Bottle Dimensions: Complete Guide for B2B Buyers (USA & Global)
What are the exact 2 kg gas bottle dimensions? A standard 2 kg N₂O (nitrous oxide) gas bottle typically measures 310 mm height × 115 mm diameter (with valve height up to 340 mm). However, dimensions may vary slightly between manufacturers due to neck finish and valve design. This guide provides verified measurements, certification requirements, and sourcing insights for import managers, brand owners, wholesalers, and sourcing agents looking to buy 2 kg gas bottle dimensions that meet US DOT / TC / UN standards.
Why Accurate Sizing Matters for Your Business
Many buyers face three core pain points when procuring small gas cylinders:
- Incompatibility with filling stations or dispensers – different valve threads (CGA-326 vs. 5/8″ UNF) cause delays.
- Shipping cost surprises – volume and weight inconsistencies lead to higher freight charges.
- Regulatory non-compliance – local import requirements (DOT 3AL, TC, UN ISO 9809) are often overlooked.
We address each point with verifiable data and custom options.
Standard 2 kg Gas Bottle Dimensions (N₂O / CO₂ / Food Grade)
Below are the typical physical specifications for a 2 kg nitrous oxide (N₂O) cylinder used in whipped cream dispensers, medical gases, and beverage carbonation. Always confirm with actual order – slight variations exist per lot.
