Eaton 2021-6-8S Steel Flared Tube Connector 1/2 in Od

Product Description

The EATON 2021-6-8S is a steel flared tube connector designed for high-pressure hydraulic and fluid transfer applications. It features a 37-degree flare seat on the tube side and a male NPT thread on the fitting end, providing a reliable Flare x MNPT connection. Built from steel, this connector handles working pressures up to 6000 psi and operates across a temperature range of -40 to 250 degrees F. At 1.53 inches overall length and weighing 0.12 pounds, it is a compact, durable fitting suited for installation by licensed plumbers, hydraulic technicians, and fluid system mechanics.

This connector is intended for use in hydraulic lines, pneumatic systems, and fluid transfer assemblies where a 1/2 inch OD flared tube must transition to a 3/8 inch male NPT port. The 37-degree flare angle conforms to SAE 070102 standards, making it compatible with standard SAE flare fittings commonly found in industrial, commercial, and mobile equipment fluid systems. It is appropriate for both shop fabrication and field service repair of hydraulic circuits and pressurized fluid lines.

Key Features

• 37-degree flare seat meets SAE 070102 standard for consistent sealing
• Maximum working pressure of 6000 psi for demanding hydraulic applications
• Operating temperature range of -40 to 250 degrees F
• Flare x MNPT end configuration transitions tube to NPT port connections
• Steel construction provides strength and durability in high-pressure service
• Compact at 1.53 inches overall length for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid transfer systems requiring a 1/2 inch OD flared tube connection to a 3/8 inch NPT male port, conforming to SAE 070102 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with SAE flare fittings and NPT thread connections. Depressurize and isolate the hydraulic or fluid system completely before removing or installing any fittings. Inspect the flare seat and NPT threads for damage before assembly, and ensure the mating tube flare is formed correctly to the 37-degree angle to achieve a proper seal. Follow applicable industry and equipment manufacturer guidelines for thread sealant use on NPT connections in the specific fluid service.
