Rigid Coupling for Grooved Pipe Systems – Reliable, Secure, and Easy Installation

Grooved pipe connection technology, also known as clamp connection, has become the preferred method for liquid and gas pipeline installations due to its efficiency, reliability, and ease of use. Widely used in automatic sprinkler systems and other fire protection piping systems, grooved connectors simplify the installation process and improve project timelines.

Our rigid couplings are designed to provide a strong and rigid connection between grooved pipes, ensuring precise alignment with minimal deflection. Made from high-strength ductile iron and finished with a durable epoxy coating or hot-dip galvanization, our rigid couplings are corrosion-resistant and built for long-term performance.

Key Features of Rigid Couplings:

Designed for zero flex and movement, ensuring system stability.
Quick and easy installation with standard tools—no welding or flanging required.
Suitable for fire protection, HVAC, industrial, and plumbing systems.
Available in sizes from 1" to 12", compliant with international standards (FM/UL certified).
Compatible with all standard grooved-end steel pipes.

By replacing traditional flange or welded joints, rigid couplings help reduce labor costs and improve safety on site. As grooved connection technology continues to gain traction globally, rigid couplings are becoming an essential component of modern pipeline systems.
