Orange ductile iron grooved concentric reducer 8 by 4 inches

Gruvlok

Gruvlok Concentric Reducer 8" x 4" Ductile Iron 800 psi Orange

SKU CH-TQB1-QW6K5

Connects 8-inch and 4-inch grooved pipe with ductile iron rated to 800 psi and compliant with ASME B 31.1, B 31.9, ASTM A536 and NFPA 90

  • Grooved connection speeds pipe assembly
  • Ductile iron handles 800 psi service pressure
  • Concentric design keeps flow centred through reduction
  • Meets ASME B31.1, B31.9 and ASTM A536 standards
  • Bright orange finish aids on-site identification

8" x 4" Concentric Reducer for Grooved Piping

This ductile iron concentric reducer connects 8 inch and 4 inch grooved pipe ends in a straight line. It is built for pressure piping systems that require a smooth bore transition. The orange coating identifies the fitting on site.

Verify Grooved Ends and Pressure Rating

Confirm that both pipe sections use grooved mechanical couplings before ordering. The reducer is rated for 800 psi maximum working pressure and meets ASME B31.1, B31.9, ASTM A536 and NFPA 90 standards. Compliance number 39 applies.

Ductile Iron Body with Orange Finish

The ductile iron construction resists cracking under shock and vibration better than grey iron. Grooved connections allow fast assembly without welding or threading tools. The orange paint protects the surface during handling and helps visual inspection.

Questions about this item

What comes in the box and what must I supply separately?

The box contains the 8" x 4" concentric reducer made of ductile iron with grooved ends. You must provide compatible grooved couplings, gaskets and pipe sections to complete the joint.

How do I decide which size reducer to select?

Choose this model when you need to transition from an 8 in nominal grooved pipe to a 4 in nominal grooved pipe in a system rated for 800 psi.

What does the 800 psi rating mean once the fitting is installed?

It indicates the maximum working pressure the ductile iron reducer can withstand when assembled with listed grooved couplings per ASME B 31.1 and B 31.9.
