M2/M3-Series Bradleys… New NBC Hose DisconnectPosted: 2015/13/10
Crewmen, if your Bradley is still equipped with the NBC quick disconnect for the M42 protective mask, you’ll need to get it ready for the newly-fielded M51 protective mask.
That means replacing the NBC heater hose’s current quick connect adapter, NSN 4240-01-486-7210, with a new style quick disconnect coupling half, NSN 4730-00-935-1643. You’ll also need to install a new hose clamp, NSN 4730-00-541-8297.
You’ll find information on removing the old parts and installing the new ones in TM 9-2350-408-13&P in IETM EM 0356 (Apr 15).
Be sure to order enough parts for the vehicle commander, gunner and driver positions. The dismount stations will get a retrofit at a later date.
Get the parts at no charge by contacting Brianne Woodell with the Armored Brigade Combat Team at
