ABR Press On Barbed – Aluminum Couplers

This innovative coupler design combines the advantages of low cost, reliability, and a fast time saving method of installation.  Each of the barbed rings function as a separate full circumference seal providing double protection against air passing through the connection as the sharp precision cut barbs bite into the body of the duct creating a connection having both high internal and external sealing capability with exceptional pull out strength.  Sealing and tensile efficiency of the coupler actually improves as internal air pressure in the duct increases during the cable placement operation.
Being a compression type fitting, the coupler must be pushed onto the conduit under a compression load sufficient to cause the barbs to bite into the duct which requires the use of one of our hydraulic coupler presses.  A mechanically assisted installation procedure insures each coupler is installed properly, thereby increasing the overall reliability of every connection.

Aluminum couplers should NOT be installed under the following conditions:
* In wet environments or submerged in water.
* In strong acidic or alkaline environments outside the PH range of 4 to 8.
* Near salt water or direct exposure to road salt run off.
* In concrete or cement stabilized sand.
