Eaton 202702-12-12S Flared Tube Connector 3/4 in

Product Description

The EATON 202702-12-12S is a steel straight thread connector designed to join a 3/4 inch OD flared tube to a male SAE O-ring (ORB) port. It uses a 37-degree flare angle on the tube end and an O-ring boss thread on the male end to create a leak-resistant hydraulic connection. The body is steel construction rated to 6000 psi maximum working pressure, with a temperature range of -40 degrees F to 250 degrees F. This fitting is commonly specified in hydraulic lines, fluid power systems, and high-pressure fluid transfer applications where a reliable flare-to-ORB transition is required.

This connector is suited for use in industrial hydraulic systems, mobile equipment, and fluid power plumbing where a 3/4 inch OD flared tube must terminate at a male SAE O-ring boss port. The straight configuration keeps the connection in-line without angular offset, simplifying routing in tight installations. It meets SAE standard 070120 and is packaged individually, making it appropriate for both single-fitting repairs and new assembly work. Licensed hydraulic and fluid power technicians, as well as experienced industrial mechanics, are the primary installers.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/4 inch OD flared tubing with a male SAE O-ring boss port connection conforming to SAE 070120.

Installation Notes

Installation should be performed by a qualified hydraulic or fluid power technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring for damage before assembly and apply a compatible hydraulic fluid or lubricant to the O-ring prior to threading. Tighten to the fitting and port manufacturer specifications using appropriate flare fitting wrenches; do not over-torque, as steel fittings can gall or distort the flare seat.
