KB3D S10/FM12/FMJ08 Side Valve

The KB3D Side Valve is a replacement unit designed for the side port of compatible gas masks, allowing you to customise both the function and appearance of your setup.

Built to fit the S10, FMJ08, and FM12, this component replaces the original side valve assembly with a clean, threaded unit that installs securely using the included locking nut.

By default, this valve operates as an inlet, utilising a rubber umbrella valve. This rubber umbrella valve can be removed for two-way valve or it can be placed on the inside for an outlet valve.

Compatible with:
S10, FMJ08, FM12 gas masks

Gas mask not included. This listing is for the Side Valve only. This includes the rubber umbrella valve.
