This innovative coupling design combines the advantages of low cost, reliability, and a fast time saving method of installation. Each of the barbed rings functions as a separate full circumference seal providing double protection against air passing through the connection.

This series of aluminum air tight couplings incorporates the same reliable, full circumference seal used in our barbed ring compression couplings. But unlike other one piece plastic or aluminum compression couplings that have to be installed with some type of coupling press, Cabletec's reverse threaded barbed ring couplings can be installed like any ordinary reverse thread coupling. Instead of a coupling press, a special wide pitch, fast traveling thread is used to force the innerduct over the barbed ring seal.

The right hand/left hand reverse thread aluminum couplings are our most economical and versatile coupling for polyethylene innerduct. The couplings work equally well for smooth wall, corrugated, or ribbed type innerduct, and are made in all sizes of SDR and SIDR rated innerducts from 3/4" to 6". Thread-on couplings can be installed by hand or with one of Cabletec's manual or hydraulic powered coupling presses.

Cabletec's Universal Coupling can used as a general purpose coupling, but they have particular applications in situations where the conduit system is constructed with a variety of different types or sizes of innerduct. The couplings are made like our standard reverse thread couplings except the amount of taper is increased. For a given size our universal couplings are about 1" longer than standard couplings.

Cabletec's PE-PVC Transition couplings were designed as a simple, economical solution to the problem of connecting polyethylene duct to standard IPS metal or PVC pipe or fittings. The couplings are air tight to 180 lbs. psi, have high pullout strength and easily handle the leverage stresses exerted from connecting large radius sweeps and full-length pipe sections.
