Eaton 203102-8-8S Steel Swivel Nut Run Tee 1/2 in Od

Product Description

The EATON 203102-8-8S is a steel flared tube swivel nut run tee designed for use in hydraulic and fluid power line assemblies. It connects three lines in a run tee configuration with flare x swivel x flare end connections and a 37-degree flare angle conforming to SAE standards. The fitting accepts a 1/2-inch tube OD and uses a 3/4-16 SAE thread. It is rated for a maximum working pressure of 4000 psi and handles temperatures from -65 degrees F to 400 degrees F, making it suitable for demanding industrial and mobile hydraulic applications. Licensed plumbers, hydraulic system technicians, and fluid power specialists are the typical installers.

This fitting is used in hydraulic plumbing runs where a branch connection is required without changing the direction of the main line flow. The run tee orientation keeps both main-line ports in-line, reducing pressure drop across the fitting. It is suited for both stationary industrial hydraulic systems and mobile equipment hydraulic circuits. The 37-degree flare end connections are compatible with SAE J514 flare fittings, a common standard in industrial and mobile hydraulic assemblies. Sold individually, it is well-suited for single-point repairs or new installations.

Key Features

• 37-degree SAE flare angle with flare x swivel x flare end connections for leak-resistant line joints
• Rated to 4000 psi maximum working pressure for high-pressure hydraulic service
• Wide temperature range of -65 degrees F to 400 degrees F suits both cold-start and high-heat environments
• Steel construction provides strength and durability in demanding fluid power circuits
• 3/4-16 SAE thread size is a widely used standard for easy system integration
• Run tee configuration keeps main-line ports in-line, minimizing flow restriction

Compatibility

Designed for use with SAE J514 37-degree flare hydraulic fittings and tubing assemblies requiring a 1/2-inch OD tube connection with 3/4-16 SAE thread, conforming to SAE 070432 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with SAE flare fitting assembly procedures. Always depressurize and bleed the hydraulic system fully before removing or installing any fitting. Inspect flare seats on both the fitting and tubing for nicks or deformation before assembly, as damage to the seating surface is a common cause of leaks. Follow SAE J514 torque and assembly guidelines for 37-degree flare connections.
