Parker PP-00323 Male Seal-lok Hydraulic Hose Fitting

Product Description

The PARKER PP-00323 is a male Seal-Lok hydraulic hose end fitting manufactured from steel. It is designed for use in hydraulic fluid power systems where a leak-free, face-seal connection is required at the hose assembly. The Seal-Lok interface uses an O-ring face seal to eliminate thread-based leakage paths, making it well suited for high-pressure hydraulic circuits. This fitting accommodates a 3/8 inch hose and is sold in a package quantity of four. Installation is performed by licensed hydraulic technicians and fluid power specialists during hose assembly fabrication or field repair.

This fitting is used in mobile hydraulic equipment, industrial machinery, and fluid power systems requiring reliable face-seal terminations. The 3/8 inch hose size is common in mid-range hydraulic circuits found in construction equipment, agricultural machinery, and manufacturing systems. It is appropriate for both new hose assembly builds and replacement of worn or damaged fittings during scheduled maintenance.

Key Features

• Male Seal-Lok (O-ring face seal) interface eliminates thread-leak paths common to NPT or JIC connections
• Steel construction provides durability in high-pressure hydraulic service
• Fits 3/8 inch hydraulic hose diameter
• Sold in a package of four fittings per order
• Compact form factor suitable for tight routing in equipment hydraulic circuits

Compatibility

Designed as an OEM-style replacement or new-build fitting for 3/8 inch hydraulic hose assemblies using the Seal-Lok O-ring face seal standard.

Installation Notes

Hydraulic hose fittings of this type are installed by qualified fluid power technicians or hydraulic hose fabricators. Always depressurize and fully relieve hydraulic system pressure before disconnecting or replacing any hose end fitting. Inspect the O-ring sealing surface for nicks or contamination before assembly, as face-seal integrity depends on surface condition. Follow the applicable system design standards and equipment manufacturer torque guidelines during final assembly.
