Flexible Couplings and Adapters

Fernco Flexible Couplings have found wide acceptance among sewer and plumbing contractors and municipalities because of their quality and ease of installation. Fernco pipe couplings and adapters are used for all types of in-house and sewer connections: drain, waste, vent piping, house-to-main, repairs, cut- ins, conductor, roof drains and increasers-reducers. Manufacturing thousands of different flexible coupling types, Fernco has the right solution for most applications.

Made of tough elastomeric polyvinyl chloride (PVC), the flexible couplings are strong, resilient and unaffected by soil conditions. They are also resistant to chemicals, ultraviolet rays, fungus growth, and normal sewer gases due to the inert nature and physical properties of the PVC material. Fernco flexible couplings are leak-proof, rot-proof and seal against infiltration and exfiltration, giving you confidence in your pipe connections.

Stock Couplings

Fernco's standard flexible couplings are leak-proof, rot-proof and seal against infiltration and exfiltration. Sizes 3/4” and larger.

Eccentric Series

Eccentric flexible couplings maintain a continuous flow-line in critical grade conditions by aligning the pipes inside walls.

Corrugated Pipe Series

Flexible couplings for corrugated pipe connect drainage or irrigation system tubing to PVC sewer piping quickly and securely.

Ultra-Rib Sewer Pipe Series

Ideal for sewer pipe connections, the ultra-rib flexible coupling connects ETI to AC or DI and ETI to SDR-35.

Large Diameter Series

For repair, alterations or rehabilitation of large diameter sewer pipe. Large diameter flexible couplings are ideal for non-standard or special size applications.

Plastic Socket Couplings

Plastic socket couplings create socket-to-pipe and socket-to-socket connections easily and reliable. Compatible with plastic traps.

Pipe Sleeve Seals

Seals pipe sleeves and carrier pipes for above and below ground applications.

Expansion Joint Coupling

Expansion joints allow the thermal expansion and contraction of vertical pipes. Ideal as an alternative for DWV offsets and drain, waste, vent staks and interior rain water conductor systems.

Qwik Tees & Ells

Flexible Tees and Elbows create up to 90˚ connections of all common household drain, waste and vent pipes. Ideal replacement for fittings at the joint.

Series 300 Stainless Steel Clamps

Their interlocking housing and band design strengthens under tension to ensure a positive seal.

Ratchet Torque Wrenches

5/16” reversing torque wrench makes quick and accurate work of clamp tightening.

Flexible Tap Saddles

The faster & less costly way to make sewer main connections. Ensures a soil-tight seal.
