Threaded PVC couplings are for making threaded connections with PVC pipe. Our durable Schedule 40 threaded couplers are available in standard white PVC or UV resistant gray PVC. These PVC threaded coupler fittings are ideal for sprinkler system installations, where long runs of PVC pipe are made using coupling fittings. Pipe tape or PVC primer and glue (sold separately) are required for proper use of these couplings. Make installations fast, easy, and inexpensive with our reliable threaded PVC couplings.
