Parker 10 P5ON-S Hex Plug 7/8-14 Msto-ring 6000 Psi

Product Description

The PARKER 10 P5ON-S is a male straight thread O-ring hex plug designed to seal and cap hydraulic and industrial fluid power lines. It uses a 7/8-14 male straight thread O-ring connection, which creates a positive, leak-resistant seal at the thread face rather than relying on a tapered pipe thread. Rated to 6,000 psi maximum working pressure, this plug is built for demanding high-pressure applications in hydraulic systems, mobile equipment, and industrial machinery. Installation is handled by licensed mechanics, hydraulic specialists, or industrial maintenance technicians.

This hex plug is suited for use in hydraulic manifolds, valve bodies, cylinder ports, and fluid power circuit blocks where an unused port must be sealed under high-pressure conditions. It is appropriate for both stationary industrial hydraulic systems and mobile hydraulic equipment. The 1-inch hex drive allows easy installation and removal with standard hand tools. The plug ships individually and is typically used as a service replacement or system build-out component.

Key Features

• 7/8-14 male straight thread O-ring connection for a leak-resistant face seal
• Rated to 6,000 psi maximum working pressure
• 1-inch hex size for standard wrench installation
• 15/16-inch overall length for compact port sealing

Compatibility

Designed as an OEM-style replacement or service component for hydraulic systems and fluid power circuits using 7/8-14 male straight thread O-ring ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any port plug. Verify the O-ring is seated properly and undamaged before torquing the plug into the port. Follow the equipment manufacturer's port plug torque specifications and applicable fluid power standards for straight thread O-ring fittings.
