Bottle Air Vent 3/8" is rated 4.6 out of 5 by 8.
Rated 5 out of 5 by from Very convenient replacement Comes with a 3/8 threaded male/female coupler with a spring loaded cutoff valve so if the air vent ever needs a quick service it can be removed and reinstalled without having to drain the system down. It’s well designed, robustly made and has a good positive vent cutoff mechanism to prevent weeping leaks. Very pleased.

Rated 5 out of 5 by from Bottle Air Vent Bought this to replace the one supplied with the water tank which failed under pressure. Easy to fit, the one way valve made it possible to fit even with the tank virtually full as I could swap it quickly
