STF Series Fiberglass Split Test Fittings

PCI STF Series Split Test Fittings provide a solution for testing secondary piping in new construction and repair applications. They can also replace damaged or deteriorated rubber test fittings.
Built from 100% fiberglass and compatible with double wall containment systems, the STF Series can remain installed after testing while leaving the secondary piping open.
Double Wall Compatible
STF Series fittings are compatible with double wall containment systems.
Secondary Piping Testing
The STF Series supports testing of secondary piping in both new installations and existing systems, with models available for RTIIA and LCX piping.
Leave-in-Place Design
