RB17 - 14 Bar First Stage Pressure Relief Valve (Oxygen Clean)

The RB17 is an over-pressure valve that screws into a spare low pressure port on your first stage.

If the high pressure seat fails on your first stage, the RB17 will vent when the interstage pressure reaches 14 bar and so prevents high pressure gas delivery to your second stage.
