Manual Push-Pull valve allows air-tight closure of air system. In full pull possition is valve closed (air can not flow through valve button. When is valve button pushed, air flow thought valve button in/out system. Valve can be pushed easily but not oppened by air pressure. It gives enough air to breath through when oppened and than it is ideal to be a first part of the brething system (closest to a gasmask).
Threads are optional. Two designs of valve are possbile:
T shape - push button is on side of go-through tube. End A and B are optional (side screws)
L shape - valve is blind end of branch, if closed. Just end A is optional (end B is not used.)
End A and B can have NATO or anesthetic cone (22mm) conections.
F - inner NATO40 thread (usualy on gas masks)
M - outer NATO40 thread (usualy on filters)
anF - anesthetic cone (aperture, 22mm aprox.)
anM - anesthetic cone (tube, 22mm aprox.)
F threads are freely rotable which helps to screw fitting to device/accessory.
Colour of threads is optionable, body is made from gray plastics. Made from durable plastic.
Basic thread for most of common gas masks and accesories is based on NATO40 standard thread. We designed special thread compatible with "west" (NATO gasmask system, like polupar british S10 gas mask) and "east" (e.g. soviet GP-5 gas masks).
