Rated 5 out of 5 by from Good value, useful features This is a good value product. I particularly like the automatic shut off valve feature that allows the vent to be easily removed for servicing or replacement without draining/depressurising the system

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.
