Eaton 202702-6-4S Flared Tube Straight Thread Connector

Product Description

The EATON 202702-6-4S is a steel straight thread connector designed to join 1/4 inch OD flared tubing to a 3/8 inch male SAE O-Ring Boss (ORB) port. The 37-degree flare seating surface provides a reliable metal-to-metal seal at the tube end, while the SAE O-Ring end ensures a leak-resistant connection at the port. Rated for working pressures up to 9000 psi and a temperature range of -40 degrees F to 250 degrees F, this fitting is built for demanding hydraulic and fluid system applications. Licensed HVAC technicians, plumbers, and hydraulic system technicians install this type of connector in both new construction and repair applications.

This connector is suited for use in hydraulic lines, refrigeration systems, and high-pressure fluid transfer assemblies where a flared tube must transition to an ORB-threaded port. Typical installations include mobile hydraulic equipment, industrial machinery fluid circuits, and high-pressure tubing runs that require a straight inline connection. The steel construction handles the mechanical stress of high-pressure environments. Package quantity is one piece per order.

Key Features

• 37-degree flare end mates with standard SAE flared tubing for a secure metal-to-metal seal
• Male SAE O-Ring Boss (ORB) thread end reduces the risk of port leakage
• Rated to 9000 psi maximum working pressure for demanding hydraulic service
• Operating temperature range of -40 degrees F to 250 degrees F
• Steel construction provides durability in high-pressure fluid system environments
• Conforms to SAE 070120 standard

Compatibility

Designed as an OEM-style replacement or new-installation straight thread connector for hydraulic and fluid systems using 1/4 inch OD flared tubing and 3/8 inch male SAE O-Ring Boss ports per SAE 070120.

Installation Notes

A licensed technician or qualified mechanic should depressurize and isolate the hydraulic or fluid circuit completely before removing or installing this fitting. Inspect the flare seat and O-Ring sealing surface for damage before assembly. Use the appropriate flare nut wrench or crowfoot to avoid rounding the fitting, and ensure the SAE O-Ring is properly seated before tightening the ORB end. Follow applicable SAE and system manufacturer guidelines for assembly procedures.
