The SharkBite? PVC x PVC slip coupling is a repair coupling that allows you to make a quick and easy repair on PVC pipe (SCH 40, 80 and 120.) The slip coupling allows up to 2 in of damaged pipe to be removed and repaired. Insert the slip coupling onto the PVC pipe and use the PVC depth gauge and disconnect clip to slip the fitting back onto the other end of the pipe, completing the connection.
