Gruvlock® Lightweight Flexible Couplers, Series L, 300 - 500 PSI

Victaulic®-style Grooved Fittings are designed for commercial/industrial construction, water transfer, and fire protection plumbing applications. These grooved lightweight flexible couplers connect other grooved end fittings while providing minimum pressure drop and maintaining uniform strength. Grooved lightweight couplers are constructed of ductile iron with rust-inhibiting paint. 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 500 PSI for 1-1/2" & 2"; 300 PSI for 2-1/2" – 12". Other sizes are available to those shown.

Note: These grooved ductile iron flexible couplers are comparable to Victaulic® #75 grooved fittings and Grinnell #7000 grooved fittings.
