Aluminum Tapered Universal Couplers
US Coupler's Tapered Universal Couplings 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.
The couplings work equally well with corrugated, ribbed, or smooth-wall conduit. US Coupler's Tapered Universal Couplings are widely used in repair work and are a practical, inexpensive way of reducing inventory costs.
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 stabalized sand.
