  • UL Listed for safety compliance
  • Grooved connection fits 4 inch pipe size

4" Grooved Coupling Class 150

The Anvil 4 inch grooved coupling is a pipe fitting designed for joining grooved-end pipes in fire protection, HVAC, and general piping systems. It suits mechanical contractors, maintenance engineers, and installers who need a reliable rigid joint for 4 inch nominal pipe size.

Ductile iron construction with UL Listing

The coupling body meets ASTM A536 and ASTM A47 standards, providing ductile iron strength for a maximum working pressure of 450 psi. Two-bolt housing with 3/4 inch hex bolts allows fast installation using standard hand tools. The grooved connection type eliminates threading or welding, reducing on-site labour. Operating temperature range spans -40 to 250 degrees F, covering chilled water and heating circuits alike.

Verify pipe OD and groove dimensions before ordering

Confirm the existing pipe has an outside diameter of 4 1/2 inches and standard cut-groove profile compatible with Class 150 housings. Ensure system design pressure does not exceed the 450 psi rating and that the temperature range matches service conditions. Check that two-bolt rigid coupling suits the required joint rigidity; flexible couplings may be needed for vibration or movement accommodation.
