Transition Built in Bushing

Calder Repair Coupling (CRC) for leak-proof, root-resistant seals on virtually any main line 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.

Sealing Ridges: Molded into each coupling to prevent pipe from shifting or slipping. Create the tightest seal possible.

Corrosion Resistant: Stainless steel clamps (available in 304 and 316) form a leak-proof seal, delivering the greatest corrosion resistance possible.

Nut and Bolt Clamp Design: More durable than traditional worm drive design. (Worm gear clamps available).
