This fitting can be used equally well as either a normal pipe coupling or a slip coupling.Slip couplings are ideal for use when repairing damaged pipes, or in areas where space is tight as they can be slipped back and forth along the pipe and manoevred into the final position when the pipes are in place.If you are using this fitting to join a pipe that has been cut to length, you should ensure that the pipe has been chamfered and that you have lubricated the seal using SG100 lubricant - this will ensure the best possible seal.Please watch our overview video below
