40mm Gost Threaded Gas Mask Hoses
Tax included.
The Soviet Unions and subsequent Warsaw Pac countries shared a lot of designs and production of gas masks. Especially their filter threads. These 40mm gas mask hoses are GOST thread and useful for connect many cold war era gas masks with their subsequent filters. While these filters are not made with asbestos they may have been used with filter that were. We highly recommend cleaning these and using them mainly for display.
