Parker 316P-6PP 3/8 in Polypropylene Hex Nipple Mpt

Product Description

The PARKER 316P-6PP is a 3/8-inch polypropylene hex nipple designed for use in plastic pipe systems requiring male pipe thread (MPT) end connections. This fitting provides a threaded connection point between pipe segments or inline components and is manufactured from black polypropylene for resistance to a range of common chemicals and fluids. The hex profile allows a wrench to be applied for controlled tightening without marring the fitting body. Plumbers and pipefitters working on low-pressure fluid handling, irrigation, or chemical transfer systems install this type of fitting where a compact, corrosion-resistant threaded connection is needed.

This hex nipple is suited for residential and light commercial piping applications where polypropylene is the specified material. Typical installations include water treatment systems, chemical feed lines, irrigation manifolds, and process plumbing where metal fittings are not suitable due to corrosion or chemical compatibility concerns. The 3/8-inch size fits standard pipe runs in smaller-diameter distribution or supply lines. It ships individually but is subject to a minimum order quantity of 5 units.

Key Features

• 3/8-inch fitting size with MPT end connections on both ends
• Polypropylene construction provides chemical and corrosion resistance
• Hex body profile allows wrench engagement for controlled installation torque
• Black color polypropylene for UV and chemical exposure environments
• Compact design suits tight-clearance inline pipe connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 3/8-inch MPT polypropylene pipe systems in plumbing, irrigation, and fluid handling applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC guidelines. Shut off fluid supply and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to MPT threads before assembly. Do not overtighten polypropylene fittings, as the material can crack under excessive wrench load.
