Parker 1/8 Hhp-s Hollow Hex Plug Mnptf 6000 Psi

Product Description

The PARKER 1/8 HHP-S is a hollow hex plug designed for industrial pipe and fluid system applications requiring a reliable threaded closure. Machined from zinc-plated steel, this plug accepts a 1/8 inch male MNPTF thread and carries a maximum working pressure of 6000 psi. The hex drive measures 3/16 inches across flats and the overall installed length is 5/16 inches, making it well-suited for tight or confined plumbing assemblies. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of fitting when capping or plugging a live port in a pressurized line or manifold.

This plug is used in industrial hydraulic, pneumatic, and fluid power systems where a threaded port must be sealed against high-pressure flow. The MNPTF connection provides a dry-seal thread form that creates a pressure-tight joint without requiring additional thread sealant, though sealant practice should follow system specifications. Typical installation scenarios include plugging unused ports on manifolds, cylinders, valves, and distribution blocks in both stationary and mobile equipment.

Key Features

• Maximum working pressure of 6000 psi for high-pressure hydraulic and fluid power service
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• MNPTF dry-seal thread eliminates the need for tape or compound when a metal-to-metal seal is required
• Compact 5/16 inch overall length fits restricted port areas
• 3/16 inch hex size allows installation with standard hex key or socket tooling

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pipe and hydraulic systems using 1/8 inch MNPTF threaded ports rated to 6000 psi.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or hydraulic technicians. Always depressurize and isolate the system before removing or installing any threaded plug. Apply thread sealant per system design requirements and torque with a properly sized hex key to avoid stripping the fitting. Follow applicable fluid power and piping codes when servicing pressurized hydraulic or pneumatic assemblies.
