Grooved Coupling – Rigid Coupling XGQT01
Available Sizes: 1–12 inch (DN25–DN300)
Working Pressure: 300 PSI | FM Approved / UL Certified
Coating Options: Red Painted / Galvanized / Epoxy Blue / Grey
Gasket Materials: EPDM / NITRILE / SILICON
Product Overview
Koxy XGQT01 grooved rigid coupling is engineered for pipeline systems demanding structural rigidity and stable load transfer, ideal for industrial, commercial and municipal applications. With UL/FM certification and 300PSI (2.07MPa) working pressure up to 363PSI (2.5MPa), it meets international quality standards for high-pressure performance. Crafted with an integral tooth mechanism, it creates a non-yielding, leak-proof connection that eliminates angular deflection and axial displacement. Available in 1–12 inch (DN25–DN300) with multiple coating and gasket options, this rigid coupling combines the installation efficiency of grooved connections with the strength of traditional welded/flanged joints, reducing labor time while ensuring long-term reliability.

Product Features
Our tongue-and-groove rigid couplings are engineered for applications requiring structural rigidity. While grooved coupling systems are widely recognized for streamlined installation, our design stands apart:
Integral Tooth Mechanism: Built-in teeth securely grip pipe ends, eliminating unwanted flexing and ensuring reliable load transfer.
Installation Efficiency: The grooved connection system reduces installation time compared to traditional methods, ideal for tight schedules.
Certification Compliance: Specific product listings and technical data are available on FM (Factory Mutual) and UL (Underwriters Laboratories) official websites for compliance verification.
Key benefits include:
Zero Angular Deflection: Eliminates rotational or lateral movement post-installation, ensuring precise alignment in long pipeline runs.
Axial Stability: Prevents unwanted axial displacement, ideal for high-pressure applications or systems subject to mechanical stress.
Installation Simplicity: Streamlines setup in rigid pipe networks, reducing labor time while maintaining leak-proof integrity.
Ideal for industrial, commercial, and municipal applications where rigidity and reliability are critical, these couplings combine the ease of grooved connections with the strength of permanent joints.
