Gruvlok FIG 7305 HDPE Couplings

The Gruvlok FIG 7305 HDPE Coupling is a grooved HDPE pipe joint that is cost-effective, easy to assemble, eliminates the need for costly fusion equipment. Gruvlok products designed for HDPE pipe specifically must be installed using Gruvlok Xtreme Temperature Lubricant.

7305 HDPE Couplings use four bolts to grip sharply machined teeth onto the outside of the HDPE pipe, providing a secure and rigid mechanical connection with pressure capabilities that exceed the pressure ratings of the HDPE pipe itself. The low-profile contoured housing has ramps along the outside diameter, allowing the coupling to slide over most obstacles when long lengths of the pipeline are relocated.
