  • Class 150 rating supports 600 psi working pressure
  • Grooved connection enables fast, tool-free pipe joining
  • Ductile iron construction meets ASTM A47 and A536 standards
  • UL Listed for code-compliant fire protection installations
  • Operates reliably from -40 to 250 degrees Fahrenheit

3 inch grooved coupling class 150

This Anvil coupling connects 3 inch grooved pipe in fire protection and general piping systems. It carries a Class 150 rating and meets ASTM A47 and ASTM A536 standards with UL listing for code compliance.

Sustained pressure and temperature performance

The ductile iron body handles continuous working pressure up to 600 psi across a temperature range of -40 to 250 degrees F. ASTM A536 material maintains structural integrity under long-term thermal cycling without the degradation seen in lower-grade castings.

Installation practicalities

Two-bolt design with 3/4 inch hex fasteners allows standard wrench tightening on the 3 1/2 inch outside diameter housing. Misaligned pipe grooves or uneven bolt torque are the common causes of leak paths at the gasket seat.

Questions about this item

Does the coupling generate any heat or noise when the system runs continuously at 600 psi?

No, the grooved coupling is a passive mechanical joint with no moving parts, so it produces no noise, vibration or heat during continuous operation at the rated 600 psi.

What pipe and gasket must I already have to install this 3 inch Class 150 grooved coupling?

You need 3 inch grooved-end pipe or fittings and a compatible grooved-coupling gasket rated for the same Class 150 service.

Will this coupling seal reliably on older ASTM A536 ductile-iron pipe that has been in service for years?

Yes, it meets ASTM A536 and is UL Listed, so it will seal on existing grooved ductile-iron pipe within the -40 °F to 250 °F temperature range and up to 600 psi.
