Parker 20-16 F5OX-S Steel Flared Tube Connector 1-1/4 in

Product Description

The PARKER 20-16 F5OX-S is a steel straight thread connector designed to join 37-degree flared tubing to SAE O-ring boss (ORB) ports. It accepts a 1-1/4 inch tube OD on the flare end and connects to a 1-5/16 inch UNF straight thread on the SAE-ORB end. Rated to 4000 psi maximum working pressure, this fitting is built for high-pressure hydraulic and fluid power lines where a leak-free metal-to-metal or O-ring seal is required. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of connector in industrial equipment, mobile machinery, and fluid conveyance assemblies.

This connector is suited for hydraulic systems, fluid power circuits, and high-pressure tubing runs in both stationary and mobile applications. The 37-degree flare end conforms to SAE J514 flare standards, and the SAE-ORB straight thread end seals against a boss port O-ring per SAE J1926. It is commonly used wherever a rigid steel tube must transition to a manifold, valve body, pump, or cylinder port with a straight thread boss. Residential and light commercial use is limited; this fitting is primarily specified in industrial and heavy equipment environments.

Key Features

• 37-degree flare end conforms to SAE J514 for secure tube engagement
• SAE O-ring boss (ORB) straight thread end provides positive O-ring face seal at the port
• 4000 psi maximum working pressure rating for demanding hydraulic service
• Steel construction delivers strength and durability in high-pressure fluid lines
• UNF thread standard on the straight thread end ensures broad port compatibility
• Compact body dimensions support installations in tight plumbing runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems utilizing 1-1/4 inch OD 37-degree flared tubing and SAE O-ring boss straight thread ports per SAE J514 and SAE J1926 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and drain the hydraulic circuit fully before removing or installing any fittings. Inspect the flare seat and O-ring boss port for nicks or contamination before assembly, and always replace the SAE-ORB O-ring if reusing an existing port. Do not exceed the rated working pressure of 4000 psi, and torque the straight thread end to the fitting and tubing manufacturer specifications only.
