Parker 1/4 Hp-s Pipe Hex Plug 6000 Psi Mnptf

Product Description

The PARKER 1/4 HP-S is a pipe hex plug designed to seal open male-threaded ports in hydraulic, pneumatic, and industrial piping systems. Rated to 6,000 psi maximum working pressure, it is manufactured from zinc-plated steel for corrosion resistance in demanding service environments. The 1/4 inch MNPTF male thread provides a pressure-tight, tapered connection that seals on the thread form itself. With an overall length of 0.75 inches and a 9/16 inch hex drive, this plug installs with standard tools and is suited for maintenance, repair, and new construction work across a wide range of fluid power and plumbing applications.

This hex plug is commonly used to cap unused ports on hydraulic manifolds, valve bodies, cylinder ports, and industrial piping assemblies. It fits any female NPTF-threaded port calling for a 1/4 inch male plug. Typical installers include hydraulic system technicians, pipefitters, and industrial maintenance personnel working on fluid power circuits, compressed air systems, and general process piping.

Installation Notes

Installation is performed by pipefitters, hydraulic technicians, or industrial mechanics. Depressurize and isolate the system completely before removing or installing any pipe plug. Apply an appropriate thread sealant compatible with the system fluid when required by the application. Torque to the fitting manufacturer and system design specifications using a properly sized wrench on the hex flats — do not use pliers or pipe wrenches on the hex body.
