Nut & Bolt Clamp Coupling
Reliable Connections for Pipe Repairs
Built for Strength. Designed for Versatility.
Shielded, high-performance repair couplings designed to connect both same and different pipe materials and sizes. Featuring a durable stainless steel shield and nut & bolt clamps, these couplings are built to handle the job underground. They're designed to withstand substantial earth pressure, resist shear forces, and maintain proper pipe alignment — even in shifting or unstable soil conditions. Ideal for non-pressure, gravity flow applications such as sewer and storm drain systems, they’re easy to install and available in a full range of sizes.
Available Sizes:
For 4 inches (100 mm) to 27 inches (685 mm). Custom sizes available upon request.
Built Tough. Backed by Design.
- Robust Construction: Equipped with a 0.012" stainless steel shield, these strongback couplings offer enhanced structural integrity.
- Precision Fit: The integrated molded bushing ensures a secure and accurate connection between pipes.
- Flexible: Couplings connect pipe of different sizes and materials from 1.5” to 96” diameter. Custom
- Withstand Compression and Tension: Unlike other manufactures’ PVC thermoplastic couplings, we combine synthetic rubbers which allow for increased flexibility and distortion without altering essential physical of chemical resistance.
- Resists Corrosion: Rust-proof stainless steel clamping bands (304 & 316 Series Steel).
- Durable and Impervious: Leak proof, root proof, and resistant to ultra violet rays, fungus growth, chemicals, and normal sewer gases.
- Tight Fitting: Stainless steel (300 and 316 series) worm drive glamping bands hold pipe ends securely in place.
For a leak-proof, root-resistant seals on virtually any mainline sewer pipe.
Provides a positive seal against infiltration and exfiltration when resistance to heavy earth loads, shear forces and precise alignment are required.
Stainless Steel Shear Ring: Substantially thicker than many competitive products.
Corrosion Resistant: Stainless steel clamps (available in 304 & 316) form a leak-proof seal, delivering the greatest corrosion resistance possible.
Sealing Ridges: Molded into each coupling to prevent pipe from shifting or slipping. Creates the tightest seal possible.
Nut and Bolt Clamp Design: More durable than traditional worm drive design. (Worm gear clamps available)

Coupler Gasket: One-piece, precisions molded, EPDM elastomeric gasket.
Seal: The connector shall be in accordance with ASTM C923/C923M so that a positive sael is made between the Tap-N-Tee to the mainline pipe or conveyance system and between the Tap-N-Tee and lateral pipe. The sealing between the Tap-N-Tee and mainline pipe or conveyance system will be made through mechanical means that compression cast the Tap-N-Tee, with an expansion wedge, integrally with the wall of mainline pipe or conveyance system. The seal between the lateral pipe and the Tap-N-Tee is made through mecahanial means where rubber on outside of the lateral pipe is clenched by metal straps.
