Shur-Lock II Coupler | HDPE & PVC Conduit | ETL Listed

Shur-Lock II HDPE & PVC Conduit Coupler

The Shur-Lock II Coupler is a durable plastic coupler designed for joining HDPE and PVC conduit. It can also connect dissimilar conduit types, including HDPE to PVC, threaded or non-threaded metal conduit, and fiberglass (FRP) conduit.

Featuring stainless steel band clamps and a locking ring, the Shur-Lock II provides a secure connection and can be installed by one person using a 5/16" nut driver. A pre-lubricated O-ring creates an air-tight and water-tight seal, with 1"–3" sizes rated to withstand up to 125 PSI.

The re-enterable design requires no special tools and maintains the conduit’s full inside diameter without reduction. With excellent pull-out strength on HDPE, PVC, FRP, and steel, plus UV-resistant construction, the Shur-Lock II is built for reliable performance in demanding utility and electrical applications.
