Nibco ca03900 Pvc Schedule 80 Threaded Coupling 4 Inches Female X Female Dark Grey

Product Description

The NIBCO CA03900 is a PVC Schedule 80 threaded coupling designed for reliable pipe connections in industrial, commercial, and plumbing applications. This 4-inch fitting features female pipe thread connections on both ends, making it suitable for joining threaded PVC pipe lengths in high-pressure and chemically demanding environments. The dark grey color is standard for Schedule 80 PVC fittings, helping technicians and installers quickly identify the pressure rating on the job site. PVC Schedule 80 carries the highest long-term hydrostatic strength of any major thermoplastic piping material, making it a dependable choice for systems that handle aggressive chemicals, corrosive fluids, and elevated pressures. The female-by-female thread configuration allows this coupling to connect two male-threaded pipe ends with ease, creating a tight, leak-free joint when properly sealed. Threaded PVC fittings like the CA03900 are widely used in water treatment facilities, chemical processing plants, irrigation systems, pool and spa plumbing, and industrial piping networks. NIBCO PVC Schedule 80 fittings meet industry standards for dimensional accuracy and pressure performance, giving installers confidence in long-term system integrity. The coupling weighs 2.130 pounds and is manufactured from virgin PVC compound for consistent material properties throughout. When installing, use a compatible thread sealant or PTFE tape to ensure a leak-free connection. This fitting is part of the broader Chemtrol PVC Schedule 80 line, which is engineered to work alongside solvent-cement, threaded, and flanged system configurations. Whether you are building new piping runs or replacing worn couplings in an existing system, the CA03900 delivers the dimensional consistency and material strength that trade professionals depend on.

• PVC Schedule 80 construction provides maximum pressure ratings and long-term hydrostatic strength for demanding applications
• Female x female pipe thread connections on both ends allow quick assembly with male-threaded pipe without solvent cement
• Dark grey Schedule 80 color coding helps installers quickly verify pressure class during installation and inspection
