• Dive Box 1st Stage OPV

Dive Box 1st Stage OPV releases pressure in the event of over pressurisation of the 1st stage. Commonly used on argon cylinders, due to no second stage being present.

 

Some technical divers install the Dive Box 1st Stage OPV to prevent over pressurisation to their second stages, that causes free flowing at depth. It fits all 3/8” port of any 1st stage regulator.


Made of chromed brass, with a stainless steel internal spring.
