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.
PLEASE NOTE: The RB17 is not included with a replacement First Stage and needs to be purchased separately.

Great PRV, delivered with great care (too much care)
Review by Simon H. on 29 Mar 2021 review stating Great PRV, delivered with great care (too much care)
Very pleased with the two little RB17 pressure release valves, much more solid and better quality than the two previous (non-AP) ones they replaced. But over £10 postage for something that fits in a tiny envelope and isn't that much of a high-value item? Wow, that bit really blew me away. Still, these will look great on my ISC Pathfinder :-)
