Under normal operational circumstances the Overpressure Valve is maintenance free.

If catalyst / hardener leaks constantly from the 4mm hole in the s/s bottom Body (1032),
then O-rings (3316) must be replaced.

Important Note: It is essential that the internal spring tension is not disturbed in
the event of servicing this unit.

To renew front O-rings:

1. Disconnect red signal pipe. Unscrew whole assembly from catalyst pump using a

19 AF spanner on the forward stainless steel Body taking care of any small
residual pressurized catalyst as thread seal is broken. DO NOT disturb the spring
tension End Cap (0671).


2. Hold brass Body (1035) and unscrew stainless steel Body (1032). Pull Shaft

(1034), and Collar (1033) from body, replace O-rings (0750) and reassemble.
Ensure shaft is re-inserted with rounded end into the body.
