Fuseal 25/50™ PVDF piping systems are engineered to solve many of the problems associated with return air plenum piping or handling aggressive chemicals at elevated temperatures.

PVDF provides a very broad range of chemical resistance, thermal stability as well as a low flame spread and smoke density when tested in accordance to the ASTM E84.


Size Range:

  • 1½" - 6"

Pressure Rating:

  • -30 foot (15 PSI) maximum head pressure test for DWV applications
  • -Up to 50 PSI for pressure waste applications (subject to manufacturers review of design)

Operating Temperature:

  • -4°F - 284°F (-20°C - 140°C) 


  • Polyvinylidene Fluoride (PVDF)
High Temperature Service

Fuseal 25/50 PVDF handles corrosive drainage fluids up to 284°F (140°C).

Low Installation Costs

The system is quick and easy to install with GF’s electrofusion technology offering the simplest of installation procedures.

Material options

Fuseal 25/50 PVDF system uses Polyvinylidene Fluoride (PVDF) material, which is considered non-combustible as defined in UL 723. This material provides a very broad range of chemical resistance as well as a low flame spread and smoke density.

Broad Range of Fittings

The system has one of the largest fitting offerings in the industry and features numerous transition possibilities to metal, glass and other piping system materials.
