Parker PS6905JM-6-6 Orb to Orfs Hydraulic Fitting 3/8 in

Product Description

The PARKER PS6905JM-6-6 is a steel hydraulic hose fitting that transitions from a Male O-Ring Boss (ORB) thread on one end to a Male O-Ring Face Seal (ORFS) connection on the other. Rated to 5,000 psi maximum working pressure, it is built for high-pressure hydraulic lines where leak-free performance at the connection point is critical. The overall length is 2.87 inches and the body diameter is 3/8 inch. Both thread and seal configurations use a 3/8-inch thread size. Licensed hydraulic technicians and industrial fluid-power mechanics install this fitting as part of hose assembly and plumbing in mobile and stationary hydraulic systems.

This fitting is suited for hydraulic circuits requiring a reliable ORB-to-ORFS transition at the 3/8-inch hose size. Typical applications include mobile equipment, agricultural machinery, construction equipment, and industrial hydraulic power units where mixed thread standards exist across components. The PS series design is intended for use with steel hydraulic tubing and hose assemblies operating at or below the 5,000 psi working pressure rating.

Key Features

• 5,000 psi maximum working pressure for high-pressure hydraulic service
• Male ORB (SAE O-Ring Straight Thread) inlet transitions to Male Seal-Lok ORFS outlet
• 3/8-inch body diameter and 3/8-inch thread size on both ends
• Steel construction for durability in demanding hydraulic environments
• Overall length of 2.87 inches for compact installation in tight plumbing layouts
• Threaded connection type for secure, tool-tightened assembly

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a 3/8-inch Male ORB to Male ORFS transition at up to 5,000 psi in the PARKER PS series.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect the O-ring sealing surfaces on both ends for damage before assembly, and apply clean hydraulic fluid to the O-ring before threading to achieve proper seal without over-torquing. Follow the equipment manufacturer's torque specifications and applicable hydraulic system standards for the fitting size.
