Eaton 210292-6S Steel Flared Tube Cap 3/8 in Od Sae

Product Description

The EATON 210292-6S is a steel flared tube cap designed to seal hydraulic and fluid system lines with a 3/8 inch outside diameter and a 37-degree flare end connection. It uses a 9/16-18 SAE thread standard and is rated for working pressures up to 4000 psi, making it suitable for demanding hydraulic line applications. The cap measures 0.62 inches in overall length and weighs 0.05 pounds. It is installed by hydraulic system technicians, plumbers, and fluid power mechanics to cap off open flare fittings during service, system modification, or long-term storage.

This tube cap is used in hydraulic systems, fluid power lines, and plumbing assemblies where a 37-degree SAE flare end connection is present. It is appropriate for both residential and light commercial fluid system work. The operating temperature range of -40 degrees F to 250 degrees F makes it suitable for a wide range of environmental conditions. It is typically installed in situations where an open line must be temporarily or permanently sealed to prevent contamination or fluid loss.

Key Features

• Steel construction provides durability in high-pressure hydraulic environments
• Rated to 4000 psi maximum working pressure
• 37-degree SAE flare end connection per SAE 070112 standard
• Wide temperature range: -40 degrees F to 250 degrees F
• Compact at 0.62 inches overall length for tight-clearance installations
• 9/16-18 SAE thread for secure, leak-resistant sealing

Compatibility

Designed as a standard SAE 37-degree flare cap fitting for hydraulic and fluid power lines with a 3/8 inch tube outside diameter and 9/16-18 thread, conforming to SAE 070112.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Before installing or removing any tube cap, depressurize the system fully and relieve all stored fluid pressure. Use appropriate flare fitting tools and follow SAE fitting torque and assembly guidelines. Do not overtighten, as this can damage the flare seat and compromise the seal.
