Parker 316P-4-2N Nylon Hex Nipple 1/4x1/8 Mpt

Product Description

The PARKER 316P-4-2N is a nylon hex nipple designed for connecting two female-threaded fittings or ports in low-pressure pipe assemblies. Constructed from white nylon, this fitting offers good chemical resistance and is well suited for applications where metal fittings would corrode or add unnecessary weight. The male pipe thread (MPT) end connections on both ends allow straightforward installation into standard female-threaded ports. At 0.0035 pounds, it is a lightweight component sized at 1/4 inch by 1/8 inch, making it appropriate for reducing or joining pipe runs in fluid handling or pneumatic systems.

This hex nipple is commonly used in residential and light commercial plumbing, fluid transfer lines, irrigation systems, and low-pressure pneumatic circuits where nylon plastic fittings are acceptable per local codes and system pressure requirements. The 1/4 x 1/8 inch sizing makes it a standard reducing hex nipple for transitioning between two common pipe sizes. It is typically installed by plumbers, HVAC technicians, and general maintenance trades working on water, air, or compatible fluid lines.

Key Features

• Nylon construction provides corrosion resistance and lightweight handling

Compatibility

Designed as an OEM-style replacement or add-on fitting for low-pressure pipe systems using standard NPT female-threaded connections in 1/4 inch and 1/8 inch pipe sizes.

Installation Notes

Installation should be performed by a qualified plumber or technician in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the system completely before removing or installing any fittings. Apply thread sealant tape or compound rated for plastic fittings to the male threads before assembly. Do not overtighten nylon fittings, as excess torque can crack the fitting body.
