    Grooved Rigid Couplers, Galvanized Ductile Iron, Series R, 175 PSI

    Victaulic®-style Grooved Fittings are designed for commercial/industrial construction, water transfer, and fire protection plumbing applications. These lightweight grooved rigid couplers connect other grooved end fittings while providing a rigid, nonflexible pipe connection—maintaining minimum pressure drop and joint strength. Grooved rigid couplers are constructed of galvanized ductile iron. Buna gaskets are standard unless noted (EPDM & Viton® also available on most fittings). All mechanical grooved fittings are UL and FM approved. Maximum operating pressure at 70° F is 175 PSI. Other sizes are available to those shown.

    Note: These grooved ductile iron lightweight rigid couplers are comparable to Victaulic® grooved fittings and Grinnell grooved fittings.
