Orange ductile iron Clamp-T with FNPT branch 8 by 2.5 inches

Gruvlok

Gruvlok Clamp-T w/FNPT Branch 8x2.5" Iron 500psi Orange equipment

SKU CH-DEJR-WHE5T

A ductile-iron grooved clamp with a 2.5 in FNPT branch rated to 500 psi from -40 to 230 °F and compliant with ASME B 31.1, B 31.9, ASTM A536 and NFPA 80

  • Grooved connection enables fast installation without welding
  • FNPT branch provides direct threaded outlet for 2.5 in pipe
  • Ductile iron body rated to 500 psi for high-pressure service
  • Complies with ASME B31.1, B31.9, ASTM A536 and NFPA 80
  • Operating range from -40 to 230 degrees F for broad environments

Industrial Grooved Fitting for Fire Protection

The Gruvlok Clamp-T provides a grooved mechanical joint with a female NPT branch outlet for ductile iron piping. It is engineered for fire protection, HVAC and industrial piping installations that require a rigid 8 in by 2-1/2 in transition. The orange coating identifies the fitting on site and the ductile iron body meets ASTM A536 for structural integrity.

Pressure Rating and Temperature Range Define

The fitting carries a maximum working pressure of 500 psi and operates continuously from -40 to 230 degrees F. These two figures determine whether the component matches the design conditions of the sprinkler or hydronic system. Exceeding either limit voids compliance with the listed standards.

Bolt Kit and Standards Compliance Simplify

Each unit includes 3/4 x 4-1/2 in bolts sized for the 8 in housing, eliminating separate fastener sourcing. The fitting conforms to ASME B31.1, ASME B31.9 and NFPA 80, so inspectors can verify code acceptance without additional documentation. Compliance code 32 is marked on the body for quick field reference.

Questions about this item

What does the 500 psi rating mean for a grooved pipe system?

The 500 psi rating is the maximum working pressure the fitting can handle in service, so the grooved system it joins must operate at or below that limit.

Which standards govern this grooved Clamp-T and what do they cap?

It meets ASME B31.1, B31.9, ASTM A536 and NFPA 80, which together cover power piping, building services piping, ductile iron material quality and fire protection system requirements.

What bolt size is required to mount this 8 x 2.5 in Clamp-T?

The fitting uses a 3/4 x 4-1/2 in bolt for the grooved coupling assembly.
