Parker 219P-2 Hollow Hex Plug 1/8 Inch Mnptf Brass

Product Description

The PARKER 219P-2 is a hollow hex plug designed for industrial pipe systems requiring a reliable threaded closure with controlled flow or venting capability. Constructed from brass and rated to 1000 psi maximum working pressure, this plug handles temperatures from -65 degrees F to 250 degrees F. The 1/8 inch MNPTF male thread allows direct installation into a female NPT port without additional adapters. Licensed plumbers, pipefitters, and HVAC technicians install this fitting in pneumatic, hydraulic, fuel, and general-purpose fluid systems where a compact, pressure-rated plug is required.

This plug is suited for residential and light commercial applications across plumbing, HVAC, refrigeration, and industrial fluid-handling systems. Its 1/8 inch thread size fits standard small-port connections common on manifolds, valve bodies, instrument taps, and distribution headers. The brass construction resists corrosion in water, air, and many hydraulic fluids, making it a dependable choice for service panels, test ports, and pressure-tap closures in both new installation and retrofit work.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Depressurize and isolate the system fully before removing or installing any threaded plug. Apply appropriate thread sealant or PTFE tape per the system fluid and applicable code requirements. Tighten with a properly sized hex wrench or open-end wrench; do not over-torque brass fittings to avoid thread damage.
