Fernco flexible couplings have found wide acceptance among sewer and plumbing contractors and municipalities because of their quality and ease of installation. Fernco couplings are used for all types of in-house and sewer connections: drain waste, vent piping, house-to-main, repairs, cutins, conductor and roof drains and increasers reducers. Made of tough elastomeric polyvinyl chloride, they 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 material. And they're leakproof, rootproof and seal against infiltration and exfiltration. All couplings are clearly marked with part number, size, and pipe materials that the coupling will connect

Features

• Strong back RC couplings offer a 0.012 inch stainless steel shield and a molded in bushing
• Designed for resistance to heavy earth loads and shear forces and provides improved pipe alignment
• Add extra strength to just about any size fernco coupling
