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

Grooved couplings/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.

Product Overview

What are the three types of rigid coupling?

Grooved rigid coupling 3/4 cast iron Coupling YN01 couplings connect rotating members such as shafts and transmit torque and motion. Most rigid couplings are made of aluminum, steel, or stainless steel.

Rigid materials examples include corrugated and paperboard boxes, plastic bottles and boxes, aluminum cans, and glass jars. Popular applications include cereal boxes, glass bottles of spirits, cans of soup, and laundry detergent bottles.
