Rigidlok Coupling for Schedule 40 Pipe
The Gruvlok Rigidlok Coupling is a straight ductile-iron fitting painted for corrosion resistance and designed to join 2-inch grooved pipe. It suits installers building or maintaining rigid piping systems that require a secure mechanical connection. The coupling meets Class 150 specifications for standard industrial and commercial applications.
Pressure Limit at Elevated Temperature
The coupling carries a maximum operating pressure of 750 psi when the system fluid reaches 150 degrees Fahrenheit. At lower temperatures the same pressure rating applies, but designers must verify that the connected pipe and gaskets also meet the required class for the intended service conditions.
Headroom for Schedule 40 Systems
With a 750 psi rating the fitting provides ample headroom for typical Schedule 40 piping networks operating well below that threshold. It is not intended for systems that exceed the Class 150 pressure envelope or for pipe schedules with thinner walls that would reduce the allowable working pressure.

Questions about this item
Which schedule rating matches my piping system?
This coupling is rated for Schedule 40 pipe, so select it when your system uses that wall thickness.
What does the 750 psi rating mean once the coupling is installed?
It indicates a maximum operating pressure of 750 psi at 150 degrees Fahrenheit in service.
How does the grooved connection standard affect pressure limits?
The grooved ends conform to Class 150, which caps the pressure rating at 750 psi for this size.
