  • Class 150 rating handles 300 psi service pressure
  • Grooved connection enables fast pipe assembly
  • FM Approved and UL Listed for code compliance
  • ASTM A536 ductile iron resists -40 °F to 230 °F
  • Eight-hole bolt pattern fits standard 5 in flanges

5-inch Grooved Flange Coupling

This Anvil Class 150 grooved flange connects 5-inch pipe using a grooved joint method. It is intended for mechanical piping systems in commercial, industrial or fire-protection installations where a flanged connection is required.

Class 150 Pressure and Temperature Limits

The fitting carries a maximum pressure rating of 300 psi and an operating temperature range from -40 to 230 degrees F. These limits define the practical envelope for water, steam or compatible fluid service under the ASTM A536 standard.

Installation Notes and Common Issues

The flange has eight bolt holes sized for 3/4-inch hex hardware and an outside diameter of 5 9/16 inches. Installers must align the grooved pipe ends precisely and torque bolts evenly; misalignment or uneven tightening are the usual causes of joint leakage.

Questions about this item

Should I select the 5-inch grooved flange for my 5-inch pipe system?

Yes, the 5-inch pipe size matches the 5 9/16 inch outside diameter and eight-hole pattern for Class 150 flanges.

What does the 300 psi rating mean when the coupling is installed on a fire-protection line?

It indicates the maximum working pressure the grooved flange can handle continuously from -40 to 230 degrees Fahrenheit.

How does the grooved connection with 3/4-inch hex bolts limit the pressure I can apply?

The grooved joint and 3/4-inch hex hardware are rated to the same 300 psi limit under ASTM A536 with FM and UL approval.
