Parker 4 C5OX-S Steel 90 Deg Flared Tube Elbow 1/4 in Od

Product Description

The PARKER 4 C5OX-S is a 90-degree straight thread elbow fitting designed for flared tube hydraulic and fluid systems. It connects 1/4-inch OD flared tubing to SAE O-Ring Boss (ORB) ports using a 37-degree flare angle on the tube end and UNF straight threads on the port end. Constructed from steel, it is rated for a maximum working pressure of 6,000 psi and a maximum working temperature of 500 degrees F (260 degrees C). Licensed plumbers, hydraulic technicians, and fluid-power mechanics install this fitting in high-pressure line assemblies where a 90-degree directional change is required.

This fitting is suited for use in hydraulic systems, mobile equipment, and industrial fluid-power circuits where 1/4-inch OD flared tubing must terminate at an SAE-ORB port. The 37-degree flare conforms to SAE J514 and ISO 8434-2 standards, making it a standard choice for OEM and field-service applications in both mobile and stationary hydraulic systems. Typical install scenarios include pump outlet connections, valve block ports, and cylinder line routing where a compact 90-degree elbow reduces bend stress on the tubing.

Key Features

• 90-degree straight thread elbow configuration for directional routing of 1/4-inch OD flared tubing
• 37-degree flare angle per SAE J514 and ISO 8434-2 for leak-resistant tube sealing
• SAE O-Ring Boss (ORB) port end provides positive sealing at the threaded connection
• Steel construction rated to 6,000 psi maximum dynamic working pressure
• Temperature range up to 500 degrees F (260 degrees C) for high-heat service environments
• UNF thread standard with 7/16-inch thread size for common SAE port fitment

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid-power systems using 1/4-inch OD flared tubing with SAE-ORB ported components conforming to SAE J514 and ISO 8434-2 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed mechanic. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect the flare seat and ORB port for damage or contamination before assembly. Follow SAE J514 assembly guidelines for proper flare nut engagement and SAE-ORB O-ring seating to prevent leakage under pressure.
