Eaton 210292-8S Steel Flared Tube Cap 1/2 in Od 37 Degree

Product Description

The EATON 210292-8S is a steel flared tube cap designed to seal hydraulic and fluid system lines with a 1/2-inch tube outside diameter and a 3/4-16 SAE thread. The cap seats against a 37-degree flare end connection, providing a leak-resistant metal-to-metal seal. It carries a maximum working pressure of 4000 psi and handles temperatures from -40 degrees F to 250 degrees F, making it suitable for demanding fluid power and hydraulic plumbing applications. Licensed trades including hydraulic system technicians and industrial plumbers install these caps to terminate or protect open flare fittings during service, testing, or system modification.

This flared tube cap is used in hydraulic lines, fluid power systems, and high-pressure plumbing circuits where a 37-degree SAE flare end connection is present. It is well suited for both residential and commercial equipment maintenance tasks, including capping off unused ports, protecting open lines during repairs, and isolating sections of a hydraulic or refrigeration-adjacent fluid circuit. The 3/4-16 SAE thread standard makes it compatible with standard JIC and SAE 37-degree flare fittings commonly found in mobile equipment, industrial machinery, and HVAC-adjacent fluid systems.

Key Features

• 37-degree flare end connection for a metal-to-metal leak-resistant seal
• Maximum working pressure of 4000 psi for demanding hydraulic applications
• Operating temperature range of -40 degrees F to 250 degrees F
• 3/4-16 SAE thread standard for broad compatibility with JIC and SAE flare fittings
• Steel construction for durability in high-pressure fluid power environments
• Compact overall length of 0.75 inches keeps installation clearance requirements low

Compatibility

Designed as an OEM-style cap for hydraulic and fluid power lines using 37-degree SAE flare end connections with a 1/2-inch tube outside diameter and 3/4-16 SAE thread. Conforms to SAE standard 070112.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Always depressurize and bleed the system before removing or installing any fitting or cap. Hand-tighten the cap onto the flare seat first, then use a flare nut wrench to achieve a snug, leak-free connection without over-torquing the soft metal seating surface. Inspect the flare seat for damage or contamination before installation to ensure a proper seal.
