The EATON 2021-8-10S is a steel flared tube connector designed to join tubing to male NPT pipe threads in hydraulic, pneumatic, and fluid-transfer applications. It features a 37-degree flare angle on the tube end and a male NPT thread on the pipe end, forming a leak-resistant mechanical connection without welding or soldering. The connector is rated for service from -40 degrees F to 250 degrees F, making it suitable for a broad range of industrial and mechanical system environments. Overall length is 1.89 inches. Licensed HVAC technicians, pipefitters, and plumbers install this fitting in refrigerant line, hydraulic line, and general fluid-system assemblies.
This connector is used in applications that require a reliable transition from flared tubing to a threaded port or component. Common install scenarios include equipment hookups in commercial HVAC systems, hydraulic power units, fuel lines, and compressed-air distribution where a 5/8-inch tube OD and 1/2-inch NPT thread are specified. The 37-degree flare geometry conforms to SAE standard 070102, ensuring compatibility with fittings and components built to the same specification.
Designed as an OEM-style replacement or new-installation fitting for systems requiring a 5/8-inch tube OD flare connection to a 1/2-inch male NPT port, conforming to SAE 070102.
Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Depressurize and isolate the line before removing any existing fitting. Inspect the tube end for proper 37-degree flare formation using a calibrated flaring tool before making up the connection. Apply thread sealant compatible with the system fluid on the NPT threads only, keeping sealant away from the flare seating surface.
