This item replaces the side valve of S10/FM12 gas mask. This allows you to customise the colours on your mask.

This component replaces the original side valve unit on the S10.

This unit simply screwed tight with the included nut.


This item by standard is a two way valve - great for rebreathing. If you would like it to be a oneway valve you will need to use the rubber flap/valve which comes with the standard gasmask valve. The rubber flap does not make a 100% airtight seal.
