Gruvlok FIG 7307 HDPE Transition Couplings

Gruvlok FIG 7307 HDPE Transition Couplings are mechanical, HDPE pipe joints that connects HDPE pipe to Gruvlok standard weight roll or cut grooved steel pipe, lightweight roll grooved pipe, or Gruvlok grooved-end fittings and valves. These pipe fittings are cost-effective and easy to assemble, eliminating the need for costly fusion equipment. Gruvlok products designed for HDPE pipe specifically must be installed using Gruvlok Xtreme Temperature Lubricant.

7307 HDPE Couplings use four bolts to grip sharply machined teeth onto the outside of the HDPE pipe, providing a secure, rigid, and grooved connection with pressure and temperature capabilities that exceed the highest pressure and temperature ratings of the HDPE pipe. The low-profile contoured housing allows the coupling to slide over most obstacles when long lengths of the pipeline are relocated.
