Parker 316P-12-8N Nylon Hex Nipple 3/4 X 1/2 Inch Mpt

Product Description

The PARKER 316P-12-8N is a nylon hex nipple designed for low-pressure pipe connections in plumbing, irrigation, and light industrial fluid systems. Constructed from white nylon plastic, this fitting provides a lightweight, corrosion-resistant alternative to metal nipples in applications where chemical compatibility and weight are concerns. The hex body profile allows for standard wrench installation and removal. The fitting connects 3/4-inch male pipe thread on one end to 1/2-inch male pipe thread on the other, making it a practical reducing nipple for transitioning between common pipe sizes.

This hex nipple is suited for residential and light commercial plumbing applications, irrigation system assemblies, and fluid handling setups where nylon fittings are specified. It is typically installed by plumbers and irrigation technicians working with threaded plastic or compatible metal pipe systems. The MPT end connections on both ends allow direct threading into female-threaded fittings, valves, or pipe ports without adapters.

Key Features

• Reducing configuration: 3/4 inch to 1/2 inch MPT end connections

• Hex body profile accepts standard wrenches for controlled installation torque
• Lightweight at 0.0197 pounds per unit

Compatibility

Designed as an OEM-style replacement or standard component for threaded pipe systems using 3/4-inch and 1/2-inch female NPT ports in residential and light commercial plumbing or fluid handling assemblies.

Installation Notes

Installation is performed by licensed plumbers or qualified technicians working with threaded plastic pipe systems. Shut off the water supply and relieve system pressure before replacing any threaded fitting. Apply thread sealant tape compatible with nylon fittings and hand-tighten before using a wrench for final snugging. Avoid over-tightening nylon fittings, as excessive torque can crack the hex body or strip the threads.
