Grooved couplings are used to join pipes and fittings in various piping systems, including fire protection, plumbing, and industrial applications.
Mechanism:
They provide a rigid joint by firmly gripping the full circumference of grooved pipe ends, offering an economical alternative to welding, threading, or using flanges.
Components:
The coupling typically consists of two housing segments, a gasket (often rubber, visible in the image), and bolts and nuts to secure the segments around the pipe ends.
