Green Leaf CPLG150 Pipe Coupling 1-1/2 in Fipt Polypropylene

Product Description

The GREEN LEAF CPLG150 is a 1-1/2 inch polypropylene pipe coupling designed for joining same-size pipe sections in plumbing and fluid-handling systems. It features female iron pipe thread (FIPT) connections on both ends, allowing it to thread onto male-threaded pipe without additional adapters. Made from black polypropylene, this coupling resists corrosion and chemical exposure common in both potable water and industrial piping applications. It carries NSF 61 and NSF 372 certifications, confirming it meets standards for contact with drinking water and low lead content. Licensed plumbers and pipefitters install this fitting in residential, commercial, and light industrial systems.

This coupling is suited for use in water distribution, irrigation, and chemical-resistant piping systems where a durable, lightweight thermoplastic fitting is preferred over metal. FIPT x FIPT end connections make it compatible with standard MNPT-threaded pipe in 1-1/2 inch size. It is a practical choice in environments where metal fittings would face corrosion from water treatment chemicals, fertilizers, or mild acids. Typical applications include pool and spa plumbing, water treatment lines, and general-purpose fluid transfer.

Key Features

• 1-1/2 inch fitting size with FIPT x FIPT end connections for straightforward threaded assembly
• Polypropylene construction resists corrosion, chemicals, and scale buildup
• NSF 61 certified for contact with potable water systems
• NSF 372 certified for low lead content compliance
• Black color provides UV resistance for above-ground or exposed installations
• Lightweight design at 0.1345 pounds reduces handling fatigue during high-volume installs

Compatibility

Designed as an OEM-style replacement or new-installation coupling for 1-1/2 inch MNPT-threaded pipe in residential and commercial plumbing and fluid-handling systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before hand-tightening, then snug with a pipe wrench — avoid overtightening polypropylene threads, as excessive torque can crack the fitting. Pressure-test the completed assembly before returning the system to service.
