Reverse Thread Couplings | Smooth Wall | Aluminum

US Coupler Aluminum Reverse Threaded Couplers offer a reliable and efficient solution for SDR ducts with smooth walls. Engineered for strength, durability, and ease of installation, these couplers feature sharp buttress type threads that deliver high pulling load capacities, meeting or exceeding the Bellcore tensile standard of 1000 lbs. Originally developed by Cabletec, now part of US Coupler, these couplings are perfect for demanding applications in manholes, direct burial, and aerial installations.

Key Features:

• High Pulling Load Capacity: Sharp buttress threads are designed to withstand significant pulling forces, ensuring robust performance and meeting Bellcore tensile standards.
• Ease of Installation: The wide, eight-pitch thread angle reduces the number of revolutions needed for installation, saving time and effort. A long chamfered lead-in ensures straight, easy starts during installation.
• Versatile Application: Ideal for smooth wall SDR ducts in manholes, direct burial, aerial, and other applications where an air or watertight connection is not required.

Important Usage Information:

These Aluminum Reverse Threaded Couplers should NOT be installed in the following conditions:

• Wet environments or where the coupling may be submerged in water.
• Environments with strong acidic or alkaline conditions outside the pH range of 4 to 8.
• Near saltwater or where there is direct exposure to road salt runoff.
• Embedded in concrete or cement-stabilized sand.

Applications: Designed for SDR duct systems with smooth walls in various installation environments requiring high tensile strength and quick installation.
