Eaton 2021-12-8S Steel Flared Tube Connector 1/2 in Od

Product Description

The EATON 2021-12-8S is a steel flared tube connector designed for high-pressure hydraulic and fluid system applications. It features a 37-degree flare seat on one end and a male NPT (MNPT) thread on the other, providing a secure, leak-resistant connection between flared tubing and threaded ports. With a maximum working pressure of 6000 psi and a rated temperature range of -40 to 250 degrees F, this fitting is suited for demanding industrial and mobile equipment environments. The connector conforms to SAE 070102 standards and is machined from steel for durability under cyclic pressure loads.

This connector is used wherever a flared tube line must transition to a male NPT port on a valve, manifold, pump, or cylinder. Typical applications include hydraulic power units, mobile machinery, industrial fluid circuits, and compressed-fluid systems requiring a 1/2 inch OD tube connection to a 3/4 NPT threaded port. It is installed by hydraulic technicians, millwrights, and plumbers working with medium- to high-pressure steel tubing systems.

Key Features

• 37-degree flare seat conforms to SAE 070102 standard for reliable metal-to-metal sealing
• Maximum working pressure of 6000 psi for high-pressure hydraulic and fluid service
• Operating temperature range of -40 to 250 degrees F
• Flare x MNPT end configuration connects 1/2 inch OD flared tubing to 3/4 NPT threaded ports
• Steel construction provides strength under cyclic pressure and vibration loads
• Overall length of 1.85 inches keeps installations compact

Compatibility

Designed as an OEM-style replacement or service fitting for steel flared tube assemblies requiring a 1/2 inch OD, 37-degree flare inlet with a 3/4 NPT male outlet, conforming to SAE 070102 specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed tradesperson familiar with flared tube fittings and NPT thread assembly. Depressurize and isolate the fluid circuit completely before disconnecting or installing any fitting. Hand-tighten the flare nut onto the seat before applying wrench torque, and apply appropriate thread sealant to the NPT threads in accordance with the system fluid compatibility requirements. Inspect the flare seat and tube flare for defects before assembly to prevent leaks under pressure.
