Product Description
Aluminum Barbed Coupler
This line of couplers is best suited for applications which require couplers to be air tight. Each of the three precision machined barbs penetrate the outer surface of the innerduct providing an air tight seal. Not only do these barbs provide excellent sealing capability, but also provide excellent pull-out strength. This line of couplers come in sizes from 3/4" to 2". For proper installation, a hydraulic coupler press should be used.
Our couplers are air tight sufficient for blowing. They are not water tight.
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.
