Features

  • Wide tolerance to fit most conduits
  • Easy to install
  • Not air-tight or water-tight
  • Threads may reduce conduit ID
  • Self-threading, which draws each end of the conduit into the center of the coupler
  • The Riser/Plenum versions are approved for use in both Riser and Plenum applications – Riser UL 1666 & Plenum UL 2024

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.

The Split-Lock + is a split coupler produced from a glass fiber reinforced nylon resin. The coupler is heat and UV stabilized, and offers excellent impact strength. It’s reusable and is ideal for temporarily coupling conduits, particularly at slack-loop locations, and also for air-assisted jetting applications. The coupler is easily assembled using a 7/16” nut driver.

The Arctic-Lock™ Coupler is designed to withstand colder temperatures than the Clear-Lock Coupler. Arctic-Locks are designed with increased impact strength that greatly reduces the risk of cracking or shattering under installation force. The Arctic-Lock Coupler can withstand at least 35% higher impact than standard Clear-Lock Couplers (or 4.7 Jauls impact at -18C). The non-metallic construction provides excellent corrosion resistance in buried or encased applications and also has desirable dielectric properties.
