Parker 4-6 C5OLO-S Compression Tube Male Elbow 1/4 in Od

Product Description

The PARKER 4-6 C5OLO-S is a compression tube male elbow fitting designed for high-pressure hydraulic and fluid power applications. It connects a 1/4 inch outside diameter compression tube to a male O-Ring Face Seal port on one end and a male SAE O-Ring Boss port on the other. Constructed from zinc-plated steel, the fitting is rated to 6000 psi maximum working pressure, making it suitable for demanding industrial and mobile hydraulic circuits. Licensed plumbers, hydraulic technicians, and fluid power mechanics typically install this type of fitting during line fabrication or repair work on hydraulic systems.

This elbow fitting is used in applications where a 90-degree directional change is needed between a compression tube line and an ORFS or SAE-ORB port. It is commonly found in mobile equipment, industrial machinery, and hydraulic power units where zinc-plated steel hardware is specified for corrosion resistance in moderately harsh environments. The 9/16-18 UNF thread size is a standard inch-series dimension used across a wide range of OEM and aftermarket hydraulic components.

Key Features

• Dual-standard end connections: O-Ring Face Seal (ORFS) on the tube side and SAE O-Ring Boss (SAE-ORB) on the port side
• Rated to 6000 psi maximum working pressure for high-pressure hydraulic service
• Zinc-plated steel construction provides mechanical strength and moderate corrosion resistance
• 9/16-18 UNF thread size conforms to standard inch-series hydraulic fitting dimensions
• Accepts 1/4 inch outside diameter compression tube
• 90-degree male elbow configuration for directional routing in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic systems using 1/4 inch OD compression tube lines terminating at ORFS or SAE-ORB ported components.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. O-ring face seal fittings require a properly seated, undamaged O-ring to achieve a leak-free connection — inspect and replace the O-ring if there is any sign of damage or deformation. Tighten to the fitting manufacturer's standard recommendation for the thread size; do not over-tighten, as this can damage the O-ring or distort the sealing surfaces.
