Eaton 702X3 Brass Inverted Union Tee 3/16 in Flare

Product Description

The EATON 702X3 is a brass inverted union tee fitting designed for flared tube connections in hydraulic, pneumatic, and fluid transfer lines. It features a 45-degree flare angle with Flare x Flare x Flare end connections and accepts 3/16 inch tube OD with a 3/8-24 SAE thread. Rated to 2000 psi maximum working pressure and 250 degrees F, this fitting is built for demanding service conditions where a leak-free inverted flare junction is required. Licensed plumbers, hydraulic technicians, and fluid system installers specify this type of union tee when branching a single line into two paths without sacrificing pressure integrity.

The 702X3 is suited for residential and commercial fluid system applications including brake lines, fuel lines, refrigeration tubing, and hydraulic control circuits. Its compact overall length of 1.09 inches makes it practical in tight installations where space is limited. The all-brass construction resists corrosion in wet or chemically active environments, and the SAE inverted flare standard ensures dimensional consistency across compatible tubing and fittings from multiple manufacturers.

Key Features

• 45-degree inverted flare angle meets SAE, ASME, ASA, and MS standards for dimensional reliability
• Rated to 2000 psi maximum working pressure for high-pressure fluid circuit use
• Maximum working temperature of 250 degrees F (121 degrees C) suits a broad range of service fluids
• Flare x Flare x Flare end configuration allows a straight tee junction with no reducers required
• Compact overall length of 1.09 inches simplifies installation in confined spaces
• All-brass construction provides corrosion resistance in hydraulic, fuel, and refrigeration service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/16 inch OD flared tubing systems using 3/8-24 SAE inverted flare thread connections.

Installation Notes

Installation should be performed by a licensed plumber, hydraulic technician, or qualified mechanic familiar with SAE inverted flare fitting procedures. Always depressurize and drain the line before removing or installing any flare fitting. Proper tube preparation and a correctly seated flare are critical to achieving a leak-free joint — do not over-torque the fitting nut, as brass threads can be damaged. Verify all connections with an appropriate pressure test before returning the system to service.
