Dura Plastic PVC40COUPFIPFIP1 Schedule 40 Pvc Coupling

Product Description

The DURA PLASTIC PVC40COUPFIPFIP1 is a Schedule 40 PVC coupling with female iron pipe (FIP) threads on both ends, sized for 1-inch pipe connections. This fitting joins two threaded pipe sections in a straight run without reducing flow path diameter. It is used in pressure-rated water distribution, irrigation, and general plumbing systems. Plumbers and pipefitters install this coupling when making threaded unions in PVC piping runs. The FIPxFIP configuration accepts male-threaded pipe or fittings on both ends, making it a standard component in residential and light commercial plumbing assemblies.

This coupling is suited for residential and light commercial plumbing, irrigation, and water service applications where Schedule 40 PVC pressure ratings are required. It is installed in cold and ambient-temperature water lines, pool and spa plumbing, and irrigation distribution systems. The 1-inch size fits standard 1-inch NPT male-threaded pipe ends. No compatible model numbers or superseded part numbers were provided in the product data.

Key Features

• Schedule 40 PVC construction rated for standard pressure service
• FIPxFIP (female iron pipe both ends) accepts 1-inch NPT male threads on each side
• Straight coupling design maintains full 1-inch nominal flow path
• Suitable for cold water, irrigation, and general plumbing service

Compatibility

Designed as an OEM-style replacement or standard-stock fitting compatible with Schedule 40 PVC threaded piping systems using 1-inch NPT connections.

Installation Notes

Installation is typically performed by a licensed plumber following IPC or local plumbing code requirements. Shut off water supply and depressurize the line before removing or installing any threaded fitting. Apply PTFE tape or approved thread sealant to the male threads before threading into the FIP ends. Hand-tighten first, then use strap wrenches to finish — avoid over-tightening PVC threads, as this can crack the fitting.
