Orange ductile iron Clamp-T fitting with FNPT branch, grooved connection, 3 by 2 inch nominal size

Gruvlok

Gruvlok Clamp-T FNPT Branch 3x2" Iron 500psi Orange

SKU CH-F6DB-FPJWB

Ductile-iron grooved clamp with FNPT branch, 3×2 in, rated 500 psi from −40 to 230 °F, meeting ASME B31.1, B31.9, ASTM A536 and NFPA 74

  • Rated for 500 psi service pressure
  • Meets ASME B31.1 and B31.9 standards
  • Ductile iron construction resists corrosion
  • Operates from -40 to 230 degrees F
  • Grooved connection with FNPT branch outlet

3 in x 2 in Gruvlok Clamp-T

This ductile-iron Gruvlok Clamp-T provides a grooved-to-FNPT branch connection for 3 in x 2 in nominal pipe sizes. It is suited for installers who need a listed fitting that meets ASME B 31.1, B 31.9, ASTM A536 and NFPA 74 requirements. The orange finish identifies the fitting on site. It is not for systems that require a different nominal size or a non-grooved connection method.

Sustained pressure and temperature performance

The fitting carries a 500 psi maximum pressure rating across a temperature range of -40 to 230 degrees F. Bolt size is 1/2 x 2-3/4 in, giving a consistent clamp force during long-term service. Compliance reference 28 confirms the listing for the stated standards. It is not for applications that exceed the 500 psi limit or operate outside the published temperature window.

Installation practicalities

The grooved ends accept standard roll-groove or cut-groove pipe preparation, and the FNPT branch threads directly to female NPT components. Correct bolt torque on the 1/2 in hardware is essential to maintain the 500 psi seal. It is not for use with unprepared plain-end pipe or with thread sealants that are incompatible with ductile iron.

Questions about this item

How does the ductile iron construction handle heat when the system runs at 230 degrees Fahrenheit all day?

The ductile iron body is rated for continuous operation up to 230 degrees Fahrenheit, with a minimum temperature tolerance of -40 degrees Fahrenheit.

What grooved pipe and thread sealant do I need to connect this 3 by 2 inch Clamp-T to my existing piping?

You need grooved-end pipe in 3 inch and 2 inch nominal sizes, plus thread sealant compatible with the 1/2 by 2-3/4 inch bolts and FNPT branch connection.

Will this fitting meet the same ASME B 31.1 and B 31.9 standards as the older grooved couplings already in my building?

Yes, it complies with ASME B 31.1, B 31.9, ASTM A536 and NFPA 74, matching the standards referenced for existing grooved piping systems.
