Parker 218P-2 Hex Plug 1/8 Inch Mnptf Brass

Product Description

The PARKER 218P-2 is a brass hex plug designed to seal off open ports in industrial piping and fluid system assemblies. It features a 1/8 inch male MNPTF (male national pipe thread fuel) connection and is rated for working pressures up to 1000 psi. The plug is manufactured from brass, offering reliable corrosion resistance in a wide range of fluid and gas service applications. Plumbers, pipefitters, and industrial maintenance technicians install this fitting to cap unused ports on manifolds, valves, pumps, and other threaded pipe components. Its hex-head profile accepts a standard wrench for consistent installation torque.

This hex plug is suited for use in residential, commercial, and light industrial piping systems where an MNPTF-threaded port requires a pressure-rated seal. Typical applications include capping ports on hydraulic assemblies, pneumatic systems, fuel lines, and general fluid handling equipment. The brass construction makes it compatible with water, air, oil, and many fuel service environments within its rated pressure and temperature range.

Key Features

• 1/8 inch MNPTF male thread for direct port sealing on standard NPT fittings
• 1000 psi maximum working pressure rating
• Operating temperature range from -65 degrees F to 250 degrees F
• Brass construction provides corrosion resistance in fluid and gas service
• Hex-head design allows installation with a standard open-end or box wrench
• Meets SAE J530 and SAE J531 standards

Compatibility

Designed as an OEM-style replacement or service fitting for any piping assembly using standard 1/8 inch MNPTF-threaded ports rated to 1000 psi or below.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or industrial maintenance technician. Always depressurize and drain the system before removing or installing pipe plugs. Apply an appropriate thread sealant or PTFE tape to the male threads per the system fluid and applicable piping codes, such as the IPC or IFGC. Do not overtighten brass fittings, as the material is softer than steel and thread damage can occur.
