Parker 46F-2-2 Brass Flared Tube Connector 1/8 in Od

Product Description

The PARKER 46F-2-2 is a brass flared tube connector designed for use in fluid and refrigerant line assemblies where a leak-free mechanical connection is required. It features a 45-degree flare seat on one end and a female NPTF (FNPTF) threaded port on the other, allowing a flared tube to transition directly to a pipe-threaded fitting or component. Rated to 2800 psi maximum working pressure and suitable for temperatures up to 250 degrees F, this connector is built for demanding service in HVAC, refrigeration, hydraulic, and pneumatic applications. The all-brass construction resists corrosion and is compatible with a wide range of media.

This fitting is commonly installed in residential and light commercial HVAC systems, refrigeration equipment, pneumatic control lines, and hydraulic tubing assemblies. It suits any application requiring a straight flare-to-female-pipe-thread connection in a compact form factor. The 0.91-inch overall length makes it practical in tight installation spaces. Licensed HVAC technicians, refrigeration mechanics, and plumbers regularly install this type of fitting during line-set fabrication, equipment hookups, and service repairs where a 1/8-inch OD flared tube meets a 1/8-27 NPTF ported component.

Key Features

• 45-degree flare seat conforms to SAE J512 and SAE J513 standards for reliable metal-to-metal sealing
• FNPTF end provides a dry-seal pipe thread connection, reducing reliance on thread sealants
• 2800 psi maximum working pressure rating suitable for high-pressure refrigerant and hydraulic service
• Rated to 250 degrees F maximum working temperature for use in hot-gas and process lines
• All-brass construction offers corrosion resistance across a broad range of compatible media
• UL Listed fitting meeting SAE J512, SAE J513, and UL Listing standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/8-inch OD flared tubing with a 1/8-27 NPTF female threaded port.

Installation Notes

This fitting is installed by licensed HVAC technicians, refrigeration mechanics, or plumbers. Always depressurize and recover any refrigerant or fluid from the line before removing or installing fittings, following applicable safety codes. Ensure the tube end is properly flared to a 45-degree angle using a calibrated flaring tool before seating the fitting. Verify thread engagement on the FNPTF port is adequate and inspect both seating surfaces for burrs or damage before torquing to connection.
