This gas mask hose has a standard NATO40 thread, which will fit the S10 or Russian Gas Masks. It features a male thread at one end and a female thread at the other and is ideal for breath play.

It is ideal for use with my sniff boxes and air restrictors. These hoses allow you to create very imaginative kink sessions and they are a lot of fun.

Each is 50-55cm long and comes with a corrugated rubber hose. I only have a limited stock of these, and they are sure to be popular.
