Slip couplings are the most efficient way to repair a burst pipe or leak. A slip fitting does the job of two couplings and extra pipe. Only one end of the coupling has a stop, allowing the opposite end to slide freely over the end of a pipe. Simply insert the PVC Slip Coupling onto the pipe and, using a PVC Disconnect Clip & Depth Gauge, slip the fitting back onto the other end of pipe to complete the connection.
