Rigidlok Coupling for 2-1/2 in Piping
The Gruvlok Rigidlok Coupling joins 2-1/2 inch grooved pipe in straight configurations. It is built from ductile iron with a painted finish and rated for Class 150 service on Schedule 40 pipe. Mechanical contractors and maintenance teams use it to create rigid, leak-tight connections in commercial and industrial piping systems.
Pressure Rating and Temperature Limit
The coupling handles a maximum operating pressure of 750 psi at 150 degrees Fahrenheit. Ductile iron construction provides the structural strength needed for high-pressure fluid transfer without deformation. The painted coating adds a layer of corrosion resistance for typical indoor and protected outdoor installations.
Grooved Ends Simplify Assembly
Each end features a grooved profile that accepts standard roll-grooved or cut-grooved pipe, removing the need for threading or welding on site. This reduces installation time and allows for easier alignment adjustments during fit-up. No additional lubricants, coolants or software are bundled with the coupling.

Questions about this item
How do you install the Gruvlok Rigidlok coupling on Schedule 40 pipe and what step is often missed?
Cut a groove in the 2-1/2 in Schedule 40 pipe, seat the gasket, place the ductile iron housing over it, insert bolts and tighten nuts evenly; the step often missed is verifying the groove dimensions match the coupling before tightening.
What maintenance or replacement will the Gruvlok Rigidlok coupling need after installation?
The painted ductile iron housing and gasket should be inspected periodically for corrosion, cracking or leakage; replace the gasket if it hardens or shows wear, and repaint any scratched areas to maintain protection.
What is the first limit reached when the Gruvlok Rigidlok coupling runs at its 750 psi rating continuously?
The maximum operating pressure of 750 psi at 150 degrees F is the primary limit; sustained use at that pressure and temperature combination will reach the coupling's rated ceiling before other factors.
