Parker 3/4 Shp-s Square Head Pipe Plug 3/4 Inch Mnptf

Product Description

The PARKER 3/4 SHP-S is a square head pipe plug designed to seal threaded pipe openings in high-pressure hydraulic and pneumatic systems. Machined from steel, this plug accepts a 3/4 inch male MNPTF (Dryseal National Pipe Taper Fuel) thread and is rated for a maximum working pressure of 6,000 psi. The square head drive allows installation and removal with a standard wrench or socket. Licensed plumbers, pipefitters, and hydraulic system technicians use this plug to cap off ports, tee outlets, or unused branch connections during service or system modification.

This plug is suited for use in industrial piping systems, hydraulic power units, pneumatic manifolds, and fluid distribution assemblies where a reliable threaded seal is required. Its steel construction handles the mechanical demands of high-pressure service environments. The MNPTF thread form provides a pressure-tight seal without the need for a separate sealing washer, relying instead on thread engagement and the application of compatible thread sealant tape or compound.

Key Features

• Maximum working pressure of 6,000 psi for high-pressure system compatibility
• 3/4 inch male MNPTF thread for a dryseal, pressure-tight connection
• Steel construction for durability in demanding industrial environments
• Square head drive accepts standard wrenches and sockets for easy installation
• Compact dimensions suitable for tight-clearance port locations

Compatibility

Designed as an OEM-style replacement plug for industrial piping, hydraulic, and pneumatic systems using 3/4 inch MNPTF threaded ports rated at or below 6,000 psi.

Installation Notes

Installation is typically performed by licensed pipefitters, hydraulic technicians, or plumbers. Before installing this plug, depressurize and bleed down the system completely to zero psi and ensure all fluid has been cleared from the line. Apply a compatible thread sealant compound or PTFE tape to the male threads before seating the plug. Torque using a properly sized wrench on the square head; do not use pliers or pipe wrenches on the head faces, as this may damage the drive surfaces.
