Parker 1/8 Hp-s Hex Plug 1/8 Inch Mnptf 6000 Psi

Product Description

The PARKER 1/8 HP-S is a hex plug fitting designed to seal threaded pipe ports in hydraulic, pneumatic, and industrial fluid systems. It uses a male MNPTF (male national pipe thread fuel) connection to close off unused ports or end-of-line openings. Rated to 6,000 psi maximum working pressure, this plug is built from zinc-plated steel for corrosion resistance in demanding service environments. The 7/16-inch hex drive allows installation with standard hand tools. Licensed pipefitters, hydraulic technicians, and industrial maintenance mechanics typically install this type of fitting during system assembly or service.

This plug is suited for use in hydraulic manifolds, pneumatic distribution blocks, industrial piping systems, and fluid power circuits where a 1/8-inch NPT port needs to be capped or blanked. Its compact overall length of 9/16 inches makes it practical in tight manifold layouts. The zinc-plated finish provides moderate corrosion protection appropriate for indoor and sheltered industrial applications. It is sold individually but carries a minimum order quantity of 5 units.

Key Features

• 6,000 psi maximum working pressure rating for high-pressure hydraulic and pneumatic service
• MNPTF 1/8-inch male thread for secure, leak-resistant port sealing
• Zinc-plated steel construction for corrosion resistance
• 7/16-inch hex drive compatible with standard wrenches and sockets
• Compact 9/16-inch overall length suits tight manifold and block installations

Compatibility

Designed as an OEM-style replacement or service fitting for industrial piping and fluid power systems that use 1/8-inch MNPTF threaded ports.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. Depressurize and isolate the system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads per the system manufacturer and applicable plumbing or fluid power code requirements. Do not overtighten — use the hex drive and a calibrated torque approach appropriate to the port material to avoid thread damage.
