3 Bar Pressure Relief Safety Valve 3/4" BSP Female x Female

3 bar 3/4 inch BSP female x female pressure relief valve.

This size is quite unusual, normally these are found in 1/2 inch size.

Colour of plastic top may vary from picture (makes no difference to operation of valve).

The outlet from a pressure relief safety valve should be positioned in a way so as to not scald people or animals with escaping hot water or steam.
