Gruvlok 3" Coupling (Reducing) - Copper - GR x GR (EN)

Gruvlok 617-300-EN is a 3" copper reducing coupling, grooved x grooved, EN gasket.

It is part of the Gruvlok grooved copper line, used to join and route 3" copper tube in HVAC, plumbing and mechanical systems without brazing or soldering on the grooved ends. Grooved copper components are designed for copper tube sizes, so pair them with Gruvlok copper couplings and grooved copper tube rather than steel pipe components. The coupling joins two grooved ends and houses the gasket that seals the joint.

Before ordering, confirm the nominal size, the end connections, the gasket grade for the fluid and temperature, and the material or finish required for the application. Follow Gruvlok installation instructions and lubricate gaskets during assembly.
