Aluminum Threaded

Reverse-threaded aluminum coupler. Tapered threads accommodate a wide range of conduit OD's within a given conduit size. Also available in a Riser/Plenum rated version.

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.

Split-Lock +

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.
A low-cost push-on coupler with a molded rubber gripping insert. Can be used on HDPE, PVC, Fiberglass (FRE), and metal conduit. Transition couplers are used to join ducts with different outside diameters.

E-LOC
