High-performance PVC compression coupling designed to join two 1-1/4 in. IPS pipes quickly and securely. The CPC-1250 coupling provides a leak-resistant, corrosion-free connection for irrigation, pool/spa, and general plumbing use.

  • Nominal size: 1-1/4 in. IPS (fits 1-1/4 in. iron pipe size).
  • Material: Durable Type I PVC construction for long-term outdoor and potable-water service.
  • Gasket: Santoprene compression gasket on each end for reliable sealing and pull-out resistance.
  • Pressure rating: Rated to 150 PSI at 72°F for standard irrigation and plumbing conditions.
  • Length & fit: Coupling length approximately 6.1 in.; adjustable compression nuts allow final fit and alignment.
  • Certifications: NSF/ANSI 61/372 and UPC listed for potable-water compatibility where required.
  • Applications: Ideal for repair, retrofit, and new installations in irrigation, pool/spa, residential plumbing, and industrial water systems.

Easy to install with two removable compression ends and hand-tightenable nuts; no solvent welding required for compression connections. Manufactured to industry standards with a one-year limited warranty on manufacturing defects (check local codes and product documentation for full details). For best results, confirm pipe type (IPS) and follow tightening torque guidance from the manufacturer; not intended for compressed gases or applications outside published pressure/temperature ranges.
