Slip PVC couplings are for making connections with PVC pipe. Our durable PVC pipe couplings are available in a variety of sizes. Slip PVC coupler fittings are ideal for sprinkler system installations, where long runs of PVC pipe are made using coupling fittings. PVC primer and glue (sold separately) are required for proper use of these couplings. Make installations fast, easy, and inexpensive with our reliable PVC slip couplings.
