    Grooved Quick Release Couplers, Series Q, 300 PSI

    Victaulic®-style Grooved Fittings are designed for commercial/industrial construction, water transfer, and fire protection plumbing applications. These grooved quick-release couplers offer a fast, easy way to create quick connections or disconnections at a pipe joint. Grooved quick release couplings are constructed of ductile iron with rust-inhibiting paint (some sizes only available with zinc plating). An included stainless-steel locking pin through the handle prevents accidental opening of the coupling. 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 is 300 PSI at 70° F. Other sizes are available to those shown.

    Note: These grooved ductile iron quick release couplers are comparable to Victaulic® #78 grooved fittings and Grinnell #7003 grooved fittings.
