Shur-Lock II is a plastic coupler designed for coupling HDPE & PVC conduit. Can also be used to couple dissimilar conduits such as HDPE to PVC, threaded or non-threaded metal conduit, or fiberglass (FRP) conduit. The coupler features stainless steel band clamps (hand tightened using a 5/16" nut driver) and locking ring. A pre-lubricated O-ring forms an air-tight seal to withstand 125 PSI on 1" - 3" sizes. Also a specialized coupler for use by electrical installers requiring ETL/UL listing. Spreader Tools are available for sizes 3", 4", and 6" to aid in the installation process.

Experience the same fast and easy installation of our Push-Lock couplers now with a new, clear body design. Simply push the duct ends into the coupler for a locked and air-sealed assembly. Slightly shorter than the original Push-Lock, the Clear-Lock is ideal for pull boxes, vaults or other limited access areas. The non-metallic construction provides excellent corrosion resistance in buried or encased applications and also has desirable dielectric properties.
