M1 NBC Canteen Cap

US Military M1 NBC (Nuclear, Biological, Chemical) Canteen Caps are made to military standard MIL-C-51278D, and have been used by the military on 1 and 2 quart canteens for decades. They feature a valved drinking cap that permits use of the tubed drinking apparatus on military gas masks for hydration when masks are donned. The NBC mask adapter has a pressure valve fitting gasket, cover, and a coupling with a self sealing valve. The M1 accepts the drinking hose from any NATO standard military gas mask like the MSA Millennium, M-40 and MCU-2P. Fits standard military 1 Quart and 2 Quart canteens, NATO standard 28mm military canteens, and the Nalgene Canteen.

Warning: Watch out for knock-off M1 Canteen Caps, which are typically brighter in color and tend to leak.
