Parker KP80051 Hydraulic Hose Pipe Plug Fitting 6000 Psi

Product Description

The PARKER KP80051 is a hydraulic hose pipe plug fitting designed to terminate or cap hydraulic hose ends in high-pressure fluid power systems. Built from steel and rated to 6,000 psi maximum working pressure, this fitting uses the Seal-Lok face-seal design to deliver leak-free performance under demanding conditions. It is compatible with 5/8 inch (0.625 inch OD, 10 mm nominal size) hydraulic hose and measures 1.02 inches in overall length. The PNLO series designation identifies it within the Parker Seal-Lok fitting family. Installation is typically performed by hydraulic system technicians, maintenance mechanics, and fluid power specialists working on mobile or industrial hydraulic circuits.

This fitting is suited for use in mobile equipment, industrial machinery, and stationary hydraulic power units where a hose end must be capped or plugged during service, storage, or system modification. It is appropriate for residential, commercial, and industrial applications wherever steel, high-pressure pipe plug fittings are required on 5/8 inch OD hydraulic hose. The Seal-Lok face-seal interface minimizes the risk of leakage at connection points in high-cycle or high-vibration environments.

Key Features

• Steel construction for durability in demanding hydraulic environments
• Fits 5/8 inch (0.625 inch OD) hydraulic hose, 10 mm nominal size
• Compact overall length of 1.02 inches for space-constrained installations
• Meets SAE 520109 standards for hydraulic fittings

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using 5/8 inch OD (10 mm) hose in Parker PNLO Seal-Lok series applications rated to 6,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Before servicing any hydraulic connection, depressurize the entire hydraulic circuit and confirm system pressure is at zero. Follow applicable industry and equipment manufacturer torque and assembly guidelines for Seal-Lok face-seal fittings. Inspect the sealing face for nicks or contamination before assembly, as face-seal integrity is critical to leak-free performance.
