Parker 12-8 C5OLO-S Compression Tube Male Elbow Orfs Sae-orb

Product Description

The PARKER 12-8 C5OLO-S is a compression tube male elbow fitting designed to connect a 1/2 inch OD tube to a male O-Ring Face Seal port terminating in a 3/4-16 UNF SAE-ORB thread. Constructed from zinc-plated steel, this fitting provides a rated working pressure of 6000 psi, making it suited for high-pressure hydraulic lines and fluid power circuits. The ORFS end delivers a leak-free metal-to-metal seal with an O-ring seated in the face, while the SAE-ORB male thread connects to a standard boss port. Hydraulic system technicians and fluid power specialists are the primary installers of this fitting in industrial and mobile equipment applications.

This fitting is used wherever a 90-degree direction change is required between a compression-style tube run and a hydraulic manifold, valve, pump, or cylinder port with a 3/4-16 SAE straight-thread O-ring boss port. Typical applications include mobile hydraulic machinery, industrial fluid power systems, and heavy equipment plumbing where high-cycle pressure loads demand a reliable, vibration-resistant connection. The compression tube end eliminates the need for flaring and is compatible with 1/2 inch OD hydraulic tubing.

Key Features

• 6000 psi maximum working pressure rating for demanding hydraulic service
• ORFS (O-Ring Face Seal) end connection provides a leak-free seal resistant to vibration and pressure spikes
• SAE-ORB 3/4-16 UNF male thread seats directly into standard boss ports
• Zinc-plated steel construction resists corrosion in industrial environments
• 90-degree male elbow geometry allows routing changes without additional fittings
• Compression tube end accepts 1/2 inch OD tubing without flaring

Compatibility

Designed for use with 1/2 inch OD compression tube and 3/4-16 UNF SAE straight-thread O-ring boss ports in hydraulic and fluid power systems. Suitable as an OEM-style replacement or new-installation fitting wherever ORFS x SAE-ORB male elbow connections are specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect the O-ring and seating face for damage before assembly, and apply clean hydraulic fluid to the O-ring prior to torquing. Follow SAE J1926 torque specifications for the 3/4-16 thread boss port connection and verify no leaks under system pressure before returning equipment to service.
