Eaton 203102-4-4S Steel Swivel Nut Run Tee 1/4 in Od

Product Description

The EATON 203102-4-4S is a steel flared tube swivel nut run tee designed for high-pressure hydraulic and fluid-power line connections. It features a 37-degree flare geometry with flare-by-swivel-by-flare end connections, allowing a branch takeoff from a run line while keeping one end free to swivel for easier installation and alignment. Rated to 4500 psi maximum working pressure, this fitting handles demanding service conditions across a wide temperature range of -65 degrees F to 400 degrees F. Licensed plumbers, hydraulic technicians, and fluid-power specialists install this type of fitting in tubing assemblies requiring secure, leak-resistant flared connections.

This tee fitting is suited for use in hydraulic systems, refrigeration lines, fuel systems, and other fluid-power applications where 1/4 inch OD tubing with a 7/16-20 SAE thread is specified. The run tee configuration allows a single tubing run to branch off at a tee point without requiring a full union or additional adapter. The swivel nut end simplifies assembly in confined or hard-to-reach areas by allowing the nut to rotate independently during torquing. Typical installations include mobile equipment hydraulics, industrial machinery, and HVAC-adjacent refrigeration plumbing.

Key Features

• 37-degree flare angle per SAE 070432 standard ensures consistent sealing geometry
• Swivel nut end rotates independently for easier assembly in tight spaces
• Rated to 4500 psi maximum working pressure for demanding hydraulic service
• Wide service temperature range from -65 degrees F to 400 degrees F
• Steel construction for durability in high-pressure fluid-power applications
• Compact overall length of 1.92 inches suits space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for fluid-power and hydraulic tubing assemblies using 1/4 inch OD tubing with a 7/16-20 SAE thread and 37-degree flare end connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with SAE flared tube fittings and applicable fluid-power standards. Depressurize and isolate the hydraulic or fluid system fully before removing or installing any fittings. Inspect the tubing flare for uniformity and confirm the 37-degree flare angle matches the fitting seats before assembly. Do not overtighten the swivel nut; follow the applicable SAE torque guidelines for the tubing material and size in use.
