Grooved Rigid Coupling 3/4 Cast Iron Coupling YN01

Product Description Grooved rigid coupling 3/4 cast iron Coupling YN01UL/FM APPROVED Rigid Coupling: Ductile Iron, 4 in x 4 in Fitting Pipe Size, Grooved, Class 150 China grooved pipe fittings are a proven faster, easier, and safer method of joining pipe and are an economical alternative to welding, threading, or using flanges. There are two basic grooved coupling styles: Flexible grooved couplings/fittings and Rigid grooved couplings/fittings. Flexible grooved couplings/fittings allow a limited amount of angular movement. Rigid grooved couplings/fittings do not allow movement and can be used wherever immobility in the pipe joint is needed, like a flanged or welded joint.
