Parker 8-6 F5OLO-S Straight Thread Connector Orfs Sae-orb

Product Description

The PARKER 8-6 F5OLO-S is a compression tube straight thread connector designed to join hydraulic or fluid-system tubing at an O-Ring Face Seal (ORFS) end to a straight thread SAE O-Ring Boss (SAE-ORB) port. Constructed from steel, this connector is rated for a maximum working pressure of 9,200 psi, making it suitable for demanding high-pressure hydraulic circuits. The fitting uses a 9/16-18 UNF thread and accepts tubing with a 1/2-inch outside diameter. Licensed plumbers, hydraulic system technicians, and industrial maintenance professionals install this type of connector during line fabrication, equipment repair, and system assembly.

This connector is appropriate for use in hydraulic power units, mobile equipment, industrial machinery, and other fluid-power systems where a reliable, leak-resistant transition between an ORFS tube end and a SAE-ORB port is required. The O-ring face seal design on one end provides a metal-to-metal compression fitting with an elastomeric seal that resists vibration-induced loosening, while the SAE-ORB end threads directly into standard boss ports on valves, manifolds, cylinders, and pumps.

Key Features

• Maximum working pressure of 9,200 psi for high-pressure hydraulic service
• ORFS x SAE-ORB end connections for reliable port-to-tube transitions
• 9/16-18 UNF straight thread for precise, leak-resistant engagement
• Accepts 1/2-inch outside diameter tubing
• Steel construction for durability in demanding fluid-power environments
• Single-unit packaging suitable for service and repair applications

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems requiring a straight thread connector with ORFS tube end and SAE-ORB port connection in 9/16-18 UNF thread size.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid-power systems. Depressurize and fully isolate the hydraulic circuit before removing or installing any fittings. Inspect the O-ring and sealing surfaces for damage before assembly, and lubricate the O-ring with clean system fluid prior to tightening. Follow the equipment manufacturer and applicable industry standards for assembly procedures in high-pressure hydraulic applications.
