Tank Fitting for CPVC Systems

This bulkhead tank fitting connects 1 1/4 in CPVC pipe through curved or flat tank walls. It uses a female socket connection on both the inside and outside faces and relies on an EPDM gasket for a watertight seal. The part is suited for installers who need a straight-through bulkhead penetration without flanged bolt holes.

Pressure and Temperature Limits

The fitting is rated for a maximum operating pressure of 150 psi and a maximum operating temperature of 190 Degrees F. The minimum operating temperature is 40 Degrees F, so the assembly remains functional in cool-water applications. CPVC material and the EPDM gasket together handle these thermal and pressure conditions without additional reinforcement.

CPVC and EPDM Material Combination

The CPVC body provides chemical resistance for aggressive water treatment environments while the EPDM gasket seals against the tank surface. No bolt holes are present, so the fitting installs by tightening against the tank wall alone. This combination serves systems where both the piping material and the seal material must withstand elevated temperatures and pressure.

Questions about this item

How do I install the 1 1/4 in CPVC socket bulkhead fitting on a curved tank, and what step is most often missed?

Cut the tank opening to the correct diameter, insert the fitting through the wall, and hand-tighten the flange; the step most often missed is verifying the EPDM gasket seats evenly before final tightening.

What maintenance or replacement will the EPDM gasket need over time?

Inspect the EPDM gasket annually for hardening or cracks; replace it if leakage appears or after prolonged exposure near the 190 Degrees F limit.

At what pressure limit does the fitting reach its maximum rating during sustained use?

The maximum operating pressure is 150 psi; sustained operation at or above this value is the first limit encountered.
