Eaton 202702-4-4S 1/4 in Flared Tube Straight Thread Connector

Product Description

The EATON 202702-4-4S is a steel flared tube straight thread connector designed to join 1/4 inch OD flared tubing to a male SAE O-ring port. It uses a 37-degree flare angle and an O-ring boss (ORB) thread standard to create a reliable, leak-resistant connection in hydraulic and fluid system lines. The connector handles working pressures up to 9000 psi and operating temperatures from -40 degrees F to 250 degrees F. Hydraulic technicians and fluid power specialists install this fitting in systems where a flared tube end must mate to a straight-thread O-ring port without the need for a flare nut or separate seal.

This connector suits residential and commercial hydraulic circuits, pneumatic lines, and fluid transfer assemblies where compact, high-pressure fittings are required. It is appropriate for use in mobile equipment, industrial hydraulic systems, and any application governed by SAE standard 070120. The 0.17 inch inside diameter and 1.23 inch overall length make it well suited for tight routing in manifold or component plumbing where space is limited.

Key Features

• 37-degree flare angle meets SAE 070120 standard for flared tube connections
• Male SAE O-ring (ORB) end provides a positive, leak-resistant seal without pipe thread compound
• Rated to 9000 psi maximum working pressure for high-demand hydraulic service
• Operating temperature range of -40 degrees F to 250 degrees F covers most fluid power environments
• Steel construction for durability in hydraulic and industrial fluid system applications
• Compact 1.23 inch overall length supports installation in restricted-space plumbing layouts

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 1/4 inch OD flared tubing and SAE O-ring boss straight thread ports per SAE standard 070120.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the flare and O-ring seating surface for nicks or damage before assembly; a compromised seating surface can cause leaks under pressure. Follow SAE torque guidelines for ORB straight thread fittings and do not use thread sealant on the O-ring boss end.
