Grinnell® 61730ENP Transition Coupling With Grade "EN" EPDM Gasket, 3 in, Grooved, Ductile Iron, Copper Acrylic Enamel

Grinnell® Transition Coupling, Series: 617, Coupling Fitting/Connector Type, 3 in Nominal Size, Grooved, 1.89 in Thickness, 300 psi, Ductile Iron, Copper Acrylic Enamel, Industry Standards: ASTM A536, 4.57 in H x 6.65 in W

The GRINNELL Figure 617 Transition Coupling provides for a direct connection between grooved end IPS steel pipe, fittings or valves, and grooved end CTS copper tubing eliminating the need for a dielectric waterway transition fitting and couplings. The coupling is comprised of two ductile iron housings, a specially designed pressure responsive rubber transition gasket, and track bolts and nuts. The rubber gasket isolates the fluid from the coupling housings and the epoxy coated housings help to eliminate galvanic local cell and stray current problems.
