Schedule 40 compression couplings are used for fast, reliable, and leakproof pipe repairs or modifications, look no further than our. The fittings are engineered for simplicity and strength to provide a secure connection without the need for threading or solvent welding. These are ideal for professional contractors tackling a complex job or DIYers making a quick fix. They are designed to make your work easier and more efficient.

Our compression couplings are USA made from professional grade PVC and are built to last. They feature an innovative dual seal design that uses compressive force from the threaded cap to apply concentrated pressure at each connection point. The coupling combines this with gaskets, held in place in recessed grooves, to create a powerful, watertight seal that prevents fluid from ever reaching the cap’s threads. The result is a dependable, leakproof connection you can trust.

Compression couplings are ideal for a variety of applications, from repairing a broken line to adding a new branch or test connection. The wide gripping area provides a strong, uniform hold on the pipe, resisting pull-out and establishing lasting stability. Simply slide the coupling into place between two butted pipe ends, center it, and hand tighten the nuts for a secure fit.

Key Features:

  • Durable PVC Construction: Meets or exceeds ASTM D-2466 Schedule 40 wall thickness requirements for reliable strength and longevity.
  • Leakproof Duplex Seal: A heavy duty O-ring gasket and dual pressure point design ensures reliable, watertight connections.
  • Secure Gripping Power: The wide gripping surface provides a strong hold to prevent potential pull-out.
  • Easy to Install: No special tools, glues, or threading required, perfect for quick repairs and system modifications.
  • Sizing Standard: Designed for IPS sized pipe, suitable for both galvanized and plastic pipelines.
  • Fitting Sizes: Available sizes range from 1/2 inch to 6 inches.
  • Certified: NSF approved for potable water use.
  • Pressure Rated: Full service pressure ratings can range from 150 PSI, 200 PSI, or 235 PSI at 73°F depending on size and model.

Perfect for a range of applications—including irrigation, plumbing, and pool and spa applications, as well as emergency pipe repairs, adding test connections, creating temporary lines, and replacing damaged fittings—our Schedule 40 compression couplings are reusable and removable for maximum convenience and long term value. Fix pipe problems with confidence and get your system back up and running in minutes. Choose the smart solution for your next repair and add these essential fittings to your toolkit today.
