Product Description

Grooved pipe fittings are a type of mechanical pipe joining system commonly used in industrial piping applications. Rather than welding or threading pipes together, grooved fittings connect pipe via interlocking steel grooves cut circumferentially into the pipe ends.

A flexible coupling houses rubber gaskets that compress to form a pressure-tight seal between the grooves. These couplings can be installed without heat and are suitable for joining different pipe materials like steel, ductile iron.

Compared to other joining methods, grooved fittings offer several advantages. They can be installed faster without specialized skills or equipment like welders. The grooved connection is very secure and will not leak or come loose over time. Disassembly and replacement of sections is also simpler if needed.
