Ductile Iron Pipe Fittings

Gruvlok standard coupling is a flexible coupling with grooved-end pipe joints. It reduces noise and vibration transmissions and is used in plumbing, process piping, mining, oil field piping and construction applications. This ASME, ASTM and NFPA compliant coupling is used to separate pipe ends and guide the pipe into position as the bolts are tightened. It has a ductile iron body with an EPDM gasket and a grooved connection. These Gruvlok couplings can operate at temperatures ranging from -40 degrees Fahrenheit to 230 degrees Fahrenheit and are available in a variety of bolt sizes to fit pipes with different outer diameters.

The concentric reducer by Gruvlok is widely used for connecting pipe or tube sections on the same axis. It offers minimum pressure drop and uniform strength and is generally required in case of a shift in diameter between pipes. This UL-listed and FM-approved Gruvlok fitting is manufactured using ductile iron and has a maximum operating pressure of 750 psi. Choose from a wide range of Gruvlok concentric reducers in different nominal sizes on Raptor Supplies.
