LUBADUK® keeps pull tensions low; up to 74% less friction and 50% less pulling tension than with other lubricants. The effectiveness of LUBADUK® has been proven in the field and with extensive testing. Reduced cable tension (as much as 50%) greatly reduces the wear on cable pulling equipment and improves safety. A unique shear-sensitive carrying agent holds a dispersion of silicone oil and microspheres in suspension. LUBADUK® microspheres are tiny ball bearings, with diameters between 0.010” and 0.020.” Pulling cable with LUBADUK® means cable actually rolls on a layer of microspheres, which keep friction between cable and conduit extremely low. Any change in the cable contact point provides a fresh layer of microspheres, keeping friction low.

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.

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.
