Eaton 900605-12S Steel Flared Tube Sleeve 3/4 in Od 37-degree

Product Description

The EATON 900605-12S is a 3-piece steel flared tube sleeve designed for use in hydraulic and fluid-transfer tube assemblies requiring a 37-degree flare connection. The sleeve seats over the tube OD and, together with a nut and insert, creates a leak-resistant flare joint at the fitting interface. It is manufactured from steel to withstand the mechanical stress of tube flaring and the pressure demands of hydraulic lines. With a tube OD of 3/4 inch and an overall length of 0.69 inch, this sleeve meets SAE 070115 dimensional standards. It is installed by hydraulic technicians, plumbers, and fluid-power mechanics on hard-line tube runs.

This sleeve is suited for use in hydraulic systems, refrigeration hard-line assemblies, fuel lines, and other fluid-transfer circuits where a 37-degree JIC-style flare end connection is specified. Typical applications include industrial equipment, mobile hydraulic machinery, and commercial plumbing installations where steel tube lines terminate at flare fittings. The 3-piece sleeve design allows the nut and insert to be assembled separately, giving the installer flexibility when routing lines before final make-up.

Key Features

• 37-degree flare angle meets SAE 070115 standards for JIC-style flare connections
• 3/4 inch tube OD sizing fits standard hard-line tube stock
• Steel construction provides strength for high-pressure hydraulic and fluid-transfer service
• Compact 0.69 inch overall length minimizes space requirements at the fitting junction
• Flare end connection type for secure, leak-resistant tube termination
• 3-piece sleeve configuration allows independent assembly of nut, sleeve, and insert

Compatibility

Designed as an OEM-style replacement or service sleeve for steel tube assemblies with 3/4 inch OD tubing and 37-degree flare end connections conforming to SAE 070115.

Installation Notes

Installation is performed by hydraulic technicians or qualified fluid-power mechanics. Depressurize and drain the hydraulic or fluid circuit completely before disassembling any tube fitting. Use a calibrated tube flaring tool to produce a proper 37-degree flare on the tube end before seating the sleeve; an improper flare will result in a leaking joint. Inspect the sleeve seating surface for burrs or damage before final assembly and torque the fitting nut to the value specified by the system OEM or applicable SAE standard.
