Parker 10 Otx-s Steel Female Branch Tee 5/8 in Od

Product Description

The PARKER 10 OTX-S is a steel female branch tee fitting designed for flared tube connections in high-pressure fluid and pneumatic systems. It features a 37-degree flare angle with flare by female NPTF (FNPTF) end connections and a 5/8-inch tube outside diameter. Rated to 3000 psi maximum dynamic working pressure and up to 500 degrees F, this fitting is built for demanding industrial and hydraulic applications. Plumbers, pipefitters, and hydraulic system technicians install this type of fitting when a branch connection is needed off a main flared tube run while transitioning to a threaded port.

This fitting is suited for use in hydraulic lines, refrigeration tubing, and fluid power systems where a 37-degree SAE flare connection branches off a main line and terminates into a female NPTF threaded port. It conforms to ISO 8434-2 and SAE J514 standards, making it appropriate for applications requiring certified dimensional and performance compliance. The compact 3.28-inch overall length suits tight installation spaces in equipment, machinery, and mechanical rooms.

Key Features

• 3000 psi maximum dynamic working pressure for high-pressure system use
• Rated to 500 degrees F continuous working temperature
• Flare x FNPTF end connections allow transition from flared tube to threaded port
• Steel construction provides durability in hydraulic and fluid power environments
• 3.28-inch overall length suits compact installation scenarios

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic, fluid power, and refrigeration tube assemblies requiring a 37-degree flare female branch tee with a 5/8-inch tube OD and NPTF thread standard.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Depressurize and drain the system completely before removing or installing any fittings. Ensure mating flare and thread surfaces are clean and free of burrs or damage before assembly. Observe applicable standards such as SAE J514 and relevant local codes for torque procedures and system testing after installation.
