Flexible Couplings have found wide acceptance among sewer and plumbing contractors and municipalities because of their quality and ease of installation. These 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. Made of tough elastomeric polyvinyl chloride (PVC), the flexible couplings are strong, resilient and unaffected by soil conditions. They are also resistant to chemicals, ultra-violet rays, fungus growth, and normal sewer gases due to the inert nature and physical properties of the PVC material. Flexible couplings are leak-proof, rot-proof and seal against infiltration and exfiltration, giving you confidence in your pipe connections.
