High-Performance Grooved Couplings and Fittings

Grooved couplings and fittings provide a fast and efficient mechanical pipe connection solution, featuring high-strength ductile iron housings and precision gaskets to create a secure, leak-tight joint. The grooved design allows quick installation and easy disassembly using standard tools, significantly reducing labor time and installation costs compared to traditional pipe joining methods.

Engineered for durability and performance, grooved pipe couplings and fittings offer excellent sealing reliability, vibration resistance, and flexibility to accommodate system movement. Their robust structure and low-maintenance design help improve overall piping efficiency while ensuring long-term, dependable operation.

Grooved Couplings and Fittings for Superior Pipe Connections

Fast, reliable grooved couplings and fittings — connect stronger, install smarter!
Grooved Coupling Rigid Coupling

Grooved Coupling Rigid Coupling

Grooved rigid couplings use pre-formed or machined pipe grooves, ductile iron housings, and high-strength bolts to create a rigid, secure pipe connection with minimal deflection and movement. Available in sizes from 1" to 12", rated up to 300 PSI, FM Approved and UL Certified, with multiple surface finishes for corrosion protection and long-term durability.


Threaded Pipe Reducing Tee

Threaded Pipe Reducing Tee

The Threaded Grooved Reducing Tee is a compact grooved fitting designed to create a reduced threaded branch from a grooved main pipeline, combining fast grooved installation with threaded connection compatibility. As part of grooved couplings and fittings systems, it eliminates welding or cutting, reduces installation time, and ensures reliable sealing, stable pressure performance, and easy identification through clear cast markings.

45 Degree Pipe Fitting

45 Degree Pipe Fitting

The 45° grooved elbow is designed to change pipe direction at a smaller angle, providing smooth and efficient flow transition. Compared with a 90° elbow, it reduces flow resistance, improves fluid performance, and allows flexible pipe layout in limited space, with easy installation and reliable performance.
