Eaton 202702-12-8S Flared Tube Straight Thread Connector

Product Description

The EATON 202702-12-8S is a steel flared tube straight thread connector designed for hydraulic and fluid system plumbing where a flared tube end meets a male SAE O-ring port. The fitting accepts a 1/2 inch tube OD with a 37-degree flare angle and connects to a 3/4 inch ORB (O-ring boss) male thread. Built from steel, this connector is rated for demanding service conditions up to 9000 psi maximum working pressure across a temperature range of -40 degrees F to 250 degrees F. It is installed by hydraulic technicians, plumbers, and fluid power specialists in equipment requiring leak-free, high-pressure tube-to-port connections.

This connector is suited for industrial hydraulic systems, mobile equipment, and fluid power circuits where tube lines terminate at SAE O-ring boss ports. The 37-degree flare end conforms to SAE standard 070120, making it appropriate for use in original equipment and aftermarket hydraulic plumbing applications across both stationary and mobile machinery platforms. It ships individually and is available in single-piece quantities for maintenance and service use.

Installation Notes

Installation should be performed by a qualified hydraulic technician or plumber familiar with SAE flared tube fittings and O-ring boss port connections. Depressurize and drain the hydraulic circuit fully before removing or installing any fittings. Inspect the flare seat and O-ring sealing surface for damage before assembly, and ensure the SAE O-ring is properly seated to achieve a leak-free connection. Follow applicable equipment OEM service procedures and industry safety guidelines when working on pressurized hydraulic systems.
