Eaton 210292-4S Steel Flared Tube Cap 1/4 in 37 Deg

Product Description

The EATON 210292-4S is a steel flared tube cap designed to terminate or seal a 1/4-inch OD flared tube end in hydraulic, pneumatic, and fluid-system lines. The cap seats on a 37-degree flare and threads onto a 7/16-20 SAE fitting, providing a secure, leak-resistant closure. It is rated for working pressures up to 4500 psi and handles temperatures from -40 degrees F to 250 degrees F, making it suitable for demanding service environments. Plumbers, hydraulic technicians, and mechanical contractors install this fitting as a dead-end cap during system assembly, testing, or line isolation.

This cap fits standard SAE 37-degree flare tube connections with a 7/16-20 thread and a 1/4-inch tube OD. It is commonly used in hydraulic systems, refrigeration lines, fuel systems, and industrial fluid circuits where a temporary or permanent cap is needed on an open flare fitting. The steel construction holds up under high-pressure cycling and wide temperature swings typical of mobile equipment and stationary industrial systems.

Key Features

• Steel construction for high-strength, high-pressure service up to 4500 psi
• 37-degree SAE flare seat matches standard JIC and AN flare fittings
• 7/16-20 SAE thread for positive, leak-resistant engagement
• Wide temperature range: -40 degrees F to 250 degrees F
• Compact profile at 0.59 inches overall length for tight installation spaces
• Meets SAE 070112 standards

Compatibility

Designed for use with SAE 37-degree flare tube connections using a 1/4-inch tube OD and 7/16-20 thread, conforming to SAE 070112 standard fitment requirements.

Installation Notes

Installation is typically performed by a licensed plumber, hydraulic technician, or mechanical contractor. Depressurize and isolate the line completely before removing any existing fitting or installing this cap. Thread the cap onto the flare fitting by hand first to confirm proper thread engagement, then tighten with an appropriate open-end wrench. Do not overtighten, as steel-on-steel flare seats can be damaged by excessive torque.
