CO2 On/Off Valve for 20oz 16oz 9oz Tanks – 5/8-18UNF Thread Replacement Valve for Paintball, Airsoft & Sodastream Systems

High-Quality CO2 On/Off Replacement Valve – For 20oz, 16oz & 9oz Tanks

This durable CO2 on/off valve is designed as a direct replacement for standard 20oz, 16oz, and 9oz CO2 cylinders. Featuring a 5/8-18UNF thread, it fits most common CO2 tanks used in paintball, airsoft, beverage carbonation, and DIY pneumatic projects.

Instead of constantly unscrewing the entire CO2 cartridge, simply install this valve to control gas flow with a twist – turn “on” to release gas, turn “off” to stop – extending tank life and improving safety.
