Green Leaf M 1140 P Polypropylene Hex Nipple 1-1/4 in

Product Description

The GREEN LEAF M 1140 P is a 1-1/4 inch polypropylene hex nipple designed for threaded pipe assemblies in plumbing and fluid-handling systems. Constructed from black polypropylene, this fitting features male iron pipe thread (MIPT) connections on both ends and a hex body for secure wrench engagement during installation. It carries NSF61 and NSF372 certifications, making it suitable for potable water applications where lead-free compliance is required. Plumbers and pipefitters use this type of fitting to create rigid threaded connections between pipe runs, valves, and equipment in residential and light commercial systems.

This hex nipple is used in residential and commercial plumbing systems where a short threaded extension or transition between fittings is needed. The polypropylene construction offers resistance to corrosion and many common chemicals, making it a practical choice for water distribution lines, irrigation manifolds, and filtration system assemblies. The black color is standard for polypropylene pipe fittings in these applications. Installation is straightforward for any licensed plumber working on threaded plastic pipe 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 beginning any threaded fitting work. Use PTFE thread tape or an approved thread sealant rated for plastic fittings — do not overtighten, as polypropylene threads can crack under excessive torque. Avoid using pipe wrenches with aggressive jaw serrations directly on the hex body without protective padding.
