Fast and easy installation with a screwdriver, nut driver, or socket wrench. The Fernco XL Coupling is 7.75" long, creating a stronger, and more durable coupling than any other on the market. For sewer and drain, waste and vent piping.
Provides good flexible connection, as in my application, for connecting large volume(3,000 gal) above ground HDPE(plastic) water tank valve to underground PVC pipes. Slight drop & lift occurs as tank is filled and emptied. Plastic pipe connection would crack otherwise.
