Eaton GG108-NP04-12 Steel Flared Tube Adapter 1/4 in

Product Description

The EATON GG108-NP04-12 is a steel flared tube adapter designed to connect 1/4 inch OD tubing to M12 male ISO 9974 threaded ports using a 37-degree flare seat. Manufactured from steel, this adapter provides a leak-resistant mechanical connection suited for hydraulic and fluid power lines in industrial and mobile equipment applications. The flare-end design creates a metal-to-metal seal at the tube connection, reducing the need for additional sealing compounds at that interface. At 1.3 inches overall length and weighing 0.01 pounds, it is a compact fitting used by hydraulic technicians and fluid power specialists during line assembly, repair, or system modification work.

This adapter is used in hydraulic plumbing circuits where a 1/4 inch OD flared tube must transition to an ISO 9974 male threaded port. Typical applications include mobile hydraulic systems, industrial machinery, and fluid power assemblies operating within a temperature range of -40 degrees F to 250 degrees F. It is well suited for both OEM assembly and field service repairs on equipment using metric ISO port connections.

Key Features

• 37-degree flare end connection provides a reliable metal-to-metal seal at the tube interface
• M12 male ISO 9974 thread standard for compatibility with metric hydraulic port connections
• Steel construction for durability in hydraulic fluid environments
• Rated from -40 degrees F to 250 degrees F for use across a wide service temperature range
• Compact at 1.3 inches overall length for use in tight plumbing configurations
• Conforms to ISO 9974 standards for thread form and fitment

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems using 1/4 inch OD flared tubing and M12 male ISO 9974 threaded port connections conforming to ISO 9974 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before disconnecting or installing any fittings. Inspect the flare seat and mating tube flare for damage or burrs before assembly, as surface defects will compromise the metal-to-metal seal. Torque to the equipment manufacturer's specifications for M12 ISO 9974 fittings; do not overtighten, as this can deform the flare seat.
