Parker 318P-2N Nylon Pipe Plug 1/8 Inch Mpt

Product Description

The PARKER 318P-2N is a nylon plastic pipe plug designed to seal 1/8-inch male pipe thread (MPT) ports in fluid and gas systems. Made from white nylon, this plug provides a lightweight, corrosion-resistant closure for open pipe ends, unused tee or cross ports, and test ports across plumbing, HVAC, and food-service equipment applications. It meets FDA and NSF-51 standards, making it suitable for systems that contact potable water or food-grade media. Plumbers, pipefitters, and HVAC technicians install this type of fitting during system commissioning, maintenance, and pressure testing where a threaded port needs to be capped off without a metal plug.

This plug is appropriate for residential and light commercial plumbing, food-service equipment, and HVAC applications where a non-metallic, corrosion-resistant plug is required at a 1/8-inch NPT port. Its FDA and NSF-51 compliance makes it well suited for potable water lines, beverage equipment, and food-processing environments where metal plugs may not be acceptable. The MPT end connection threads directly into any standard 1/8-inch female NPT fitting, valve body, manifold, or equipment port.

Key Features

• Nylon construction resists corrosion, chemicals, and moisture without adding weight
• 1/8-inch MPT end connection fits standard female NPT ports
• FDA and NSF-51 compliant for use in potable water and food-contact systems
• White color provides easy visual identification in multi-port manifolds and panels
• Lightweight design at approximately 0.026 pounds per plug

Compatibility

Designed as an OEM-style replacement or new-installation fitting for any system with a standard 1/8-inch female NPT threaded port requiring a non-metallic plug.

Installation Notes

A licensed plumber or qualified HVAC technician should depressurize and isolate the system before installing or removing any pipe plug. Apply thread sealant tape or a compatible pipe thread compound to the MPT threads before installation to ensure a leak-free seal. Do not overtighten nylon fittings, as excessive torque can crack the fitting body. Installation should comply with applicable local plumbing codes and IFGC requirements.
