Parker 46F-4-2 Brass Flared Tube Connector 1/4 in Od

Product Description

The PARKER 46F-4-2 is a brass flared tube connector designed for use in refrigeration, HVAC, and fluid-handling systems where a reliable 45-degree flare connection is required. It features a Flare x FNPTF end configuration, connecting a 1/4-inch OD flared tube to a 1/8-27 NPTF female threaded port. Rated to 1400 psi maximum working pressure and 250 degrees F maximum working temperature, this fitting is suited for high-pressure lines carrying refrigerants, fuel, oil, or hydraulic fluids. Licensed HVAC technicians, plumbers, and mechanical contractors install this type of fitting in both new construction and service applications.

This connector is commonly used in residential and light commercial HVAC refrigerant line assemblies, fuel-delivery systems, and hydraulic or pneumatic circuits where a 45-degree SAE flare-to-NPT transition is needed. It is appropriate wherever a tubing run must terminate or transition into a threaded female port on valves, manifolds, or equipment fittings. The compact overall length of 1.01 inches makes it suitable for tight installation spaces. Compliance with SAE J512 and SAE J513 standards makes it a fit-for-purpose choice in regulated applications.

Key Features

• 45-degree flare angle conforms to SAE J512 and SAE J513 standards
• Flare x FNPTF end connection for tube-to-threaded-port transitions
• 1400 psi maximum working pressure for high-pressure service
• 250 degrees F maximum working temperature
• Compact 1.01-inch overall length for tight spaces
• UL Listed; meets NPTF thread standard for leak-free dry-seal performance

Compatibility

Designed as an OEM-style replacement or service fitting for systems requiring a 1/4-inch OD 45-degree flare tube connection to a 1/8-27 NPTF female threaded port, consistent with SAE J512 and SAE J513 flare fitting standards.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified mechanic familiar with flare fittings and threaded connections. De-energize and depressurize the system fully before removing or installing any fittings. Ensure the flare on the tubing is formed correctly with a calibrated flaring tool to the proper 45-degree angle before assembly; an improper flare is the most common cause of joint failure. Tighten to hand-tight plus the appropriate number of turns per applicable SAE or NPTF guidelines — do not overtighten, as this can crack the brass flare seat.
