Rainmaid's Poly-stretch coupling is a molded plastic fitting designed for use in repairing polyethylene sprinkler pipe. It extends so that you do not have to manipulate the sprinkler line while repairing, risking buckling and damaging the sprinkler line further. Instead, the fitting itself grows, creating a water-tight seal in any position and making for a clean and easy repair for leaking pipes.
