Orange ductile iron grooved concentric reducer 3 in by 2-1/2 in

Gruvlok

Gruvlok Concentric Reducer 3 in x 2-1/2 in 1000 psi Orange

SKU CH-REGG-QZ8C2

Connects 3-inch and 2-1/2-inch grooved pipe at 1000 psi with ductile iron construction meeting ASME B31.1 and B31.9 standards

  • Reduces pipe size smoothly with concentric 3 in x 2-1/2 in design
  • Handles demanding systems at 1000 psi maximum pressure rating
  • Ductile iron construction meets ASTM A536 for reliable strength
  • Complies with ASME B31.1, B31.9 and NFPA 83 standards
  • Bright orange finish provides clear visual identification on site

Gruvlok Concentric Reducer 3 in x 2-1/2 in

This ductile iron concentric reducer joins grooved piping systems with a 3 in by 2-1/2 in nominal size transition. It meets ASME B 31.1, B 31.9, ASTM A536 and NFPA 83 standards for pressure piping applications. The orange finish provides visible identification in mechanical rooms and industrial settings. Suitable for installers requiring a rated fitting for water, oil or gas services up to 1000 psi.

Thermals noise and power draw

As a passive pipe fitting this component generates no heat, noise or electrical draw during operation. System pressure and fluid temperature are governed by the piping design rather than the reducer itself. The ductile iron body maintains structural integrity across the rated pressure range without active cooling. Installers should verify that the surrounding insulation and support strategy matches the service conditions.

Bundled accessories and software

No accessories, gaskets, lubricant or software are included with this fitting. The orange coating is the only applied finish and serves as a visual marker rather than a protective layer. Compliance marking 40 is stamped on the body for traceability. Buyers needing grooved couplings, gaskets or installation tools must source those separately.

Questions about this item

How is the grooved concentric reducer installed and what step is often missed?

The ductile-iron fitting joins grooved pipe ends with a compatible coupling; the step often missed is verifying the groove dimensions match the coupling before tightening.

What maintenance or replacement will the fitting need later?

Inspect the orange coating and groove seats periodically for corrosion or mechanical damage; replace the fitting if the ductile-iron body shows cracks or the grooves are deformed.

What limit appears first under sustained 1000 psi service?

The 1000 psi pressure rating is the primary limit; sustained operation at that pressure can accelerate fatigue in the ductile-iron material and groove interface.
