The robust buttress-type threads are designed to handle high pulling loads, meeting or surpassing the Bellcore tensile standard of 1000 lbs. These couplers are precision-machined with a one-degree taper and feature a long chamfered lead-in for easy and straight installation. They also incorporate a wide eight-pitch thread angle, significantly reducing the number of turns needed to secure the connection. Versatile in use, these couplers are suitable for applications in manholes, direct burial, aerial installations, and more, except where an air- or water-tight seal is required. The couplers feature a smooth outer diameter (OD) for streamlined performance.
Aluminum Reverse Threaded Coupler (1.900/1-1/2")
Aluminum couplers should not be used under these conditions:
- In environments with high moisture or when submerged in water.
- In areas with strong acids or alkalis, outside the pH range of 4 to 8.
- In proximity to saltwater or exposed to runoff from road salt.
- When embedded in concrete or cement-stabilized sand.
Always consult your project engineer.
