60 to 40 Gas Mask Adapter

Don't throw that old gas mask away because you can't find reasonably priced 60mm filters! We offer new, 60mm to 40mm gas mask adapters. NATO currently issues 40mm gas mask filters for a variety of masks, but 60mm filters are somewhat hard to come by. This adapter solves the problem by allowing 60mm masks to use commonly available, and modern 40mm filters. Simply thread the adapter into your 60mm mask, then screw your 40mm filter into the adapter. The adapter adds almost no additional weight or thickness to the mask and can be easily removed and reinstalled if the need arises to change between 60mm and 40mm filters.Comes with a rubber gasket on the 40mm side to make sure of a tight seal.
