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

Product Description

The PARKER 316P-8-4N is a nylon hex nipple designed for threaded pipe connections in low-pressure fluid and pneumatic systems. Constructed from white nylon, this fitting accepts male pipe thread (MPT) end connections on both ends, transitioning from a 1/2 inch to a 1/4 inch pipe thread size. Its hex body allows for secure wrench engagement during installation, reducing the risk of cross-threading or over-torquing. At just 0.0102 pounds, the part is lightweight and well-suited for applications where corrosion resistance and non-metallic construction are required. Plumbers, HVAC technicians, and industrial maintenance professionals regularly use this type of fitting in low-pressure, non-critical line connections.

This hex nipple is used in residential and light commercial plumbing, pneumatic distribution lines, and fluid handling systems where a reducing threaded connection between 1/2 inch and 1/4 inch MPT ports is needed. Nylon construction makes it appropriate for systems handling water, certain chemicals, and compressed air where metal fittings are not required or are undesirable. It is commonly installed in manifolds, equipment ports, and panel assemblies across HVAC, plumbing, and light industrial environments.

Key Features

• Nylon construction provides corrosion resistance and lightweight performance
• Hex body allows standard wrench engagement for controlled installation
• 1/2 inch to 1/4 inch MPT reducing connection in a single fitting
• White color for easy visual identification in multi-line installations
• Weighs 0.0102 pounds, minimizing load on threaded ports

Compatibility

Designed as a standard MPT threaded reducing hex nipple for use in 1/2 inch to 1/4 inch male pipe thread applications in plumbing, pneumatic, and fluid handling systems.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC or industrial technician. Shut off system pressure and depressurize the line before removing or installing any threaded fittings. Apply appropriate thread sealant tape or compound to the MPT threads before engagement. Hand-tighten first, then use a wrench on the hex body to complete the connection without over-stressing the nylon threads.
