Nibco CD03870 Pvdf Pipe Nipple Sch 80 1 in X 4 in Mnpt

Product Description

The NIBCO CD03870 is a Schedule 80 PVDF threaded pipe nipple designed for demanding fluid-handling applications where chemical resistance and elevated temperatures are a concern. Measuring 1 inch in pipe size and 4 inches in length with male NPT (MNPT) threads on both ends, this nipple handles maximum working pressures up to 1360 psi and temperatures up to 280 degrees F. PVDF (polyvinylidene fluoride) construction makes it suitable for aggressive chemical service, ultrapure water systems, and corrosive fluid transfer lines. The red color coding aids in quick visual identification during installation and inspection. Plumbers and industrial piping contractors are the primary installers of this fitting.

This pipe nipple is used in chemical processing, industrial fluid systems, laboratory plumbing, and commercial or industrial piping runs where standard thermoplastic or metal fittings would be vulnerable to chemical attack or high-temperature degradation. Its Schedule 80 wall thickness provides the pressure ratings required for pressurized service lines. The MNPT thread pattern makes it compatible with standard threaded fittings, valves, and equipment in 1-inch pipe size systems. Applications include acid lines, solvent transfer, ultrapure water distribution, and semiconductor facility piping where PVDF is a specified material.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch Schedule 80 PVDF threaded piping systems using MNPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified piping technician familiar with thermoplastic threaded fittings. Shut down and depressurize the system fully before removing or installing any threaded nipple. Use PTFE thread tape or a thread sealant compatible with PVDF and the conveyed fluid — do not overtighten, as PVDF threads can crack under excessive torque. Follow applicable plumbing codes, including IPC or local authority requirements, for plastic pipe use in chemical or high-temperature service.
