Ipex 36451 Pvc Schedule 80 Nipple 1-1/2 in X 2 in Male Thread

Product Description

The IPEX 36451 is a Schedule 80 PVC nipple fitting designed for threaded pipe connections in potable water and general plumbing systems. Sized at 1-1/2 inches with a 2-inch overall length, it features male threaded ends on both sides for direct coupling to female-threaded fittings, valves, or equipment ports. The fitting is injection molded from gray PVC conforming to ASTM D1784, D1785, and D2467, delivering uniform wall thickness and consistent pressure-handling performance. Smooth interior walls reduce friction loss and support higher flow volume compared to conventional metal fittings. Rated to 140 degrees F, this nipple suits a range of pressurized water distribution applications handled by licensed plumbers and mechanical contractors.

This fitting is specified for potable water systems and is compliant with applicable NSF standards, making it appropriate for both residential and light commercial plumbing installations. The male-threaded-by-male-threaded configuration allows it to be used as a close or short extension nipple between two female connections. Typical install scenarios include service drops, valve isolation sections, pump discharge assemblies, and manifold connections where a short threaded extension is required between fittings or components.

Compatibility

Designed as an OEM-style Schedule 80 PVC threaded nipple for 1-1/2-inch pipe systems used in potable water distribution, irrigation, and general industrial plumbing assemblies.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Depressurize and drain the system before removing or installing any threaded fitting. Apply an NSF-approved thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus one to two turns using strap wrenches or smooth-jaw pliers — avoid pipe wrenches that can crack PVC. Do not over-torque; PVC threads are susceptible to stress fractures if over-driven.
