Parker 46F-3-2 Brass Flared Tube Connector 3/16 in Od

Product Description

The PARKER 46F-3-2 is a brass flared tube connector designed for use in fluid and pneumatic line assemblies requiring a reliable, leak-resistant connection. It features a 45-degree flare on the tube end and a female NPTF threaded port on the fitting end, creating a Flare x FNPTF configuration. The connector accommodates 3/16-inch tube OD and accepts a 1/8-27 NPTF thread. With a maximum working pressure of 1900 psi and a maximum working temperature of 250 degrees F, this fitting is built for demanding service conditions. Plumbers, HVAC technicians, and refrigeration mechanics install this type of fitting in copper and steel tubing systems where a straight inline connection is needed.

This connector is suited for residential and light commercial applications including refrigeration lines, fuel systems, hydraulic circuits, and pneumatic assemblies where 3/16-inch tubing terminates at an NPT-ported component such as a valve, pump, or manifold. The 45-degree flare geometry conforms to SAE J512 and SAE J513 standards, making it a direct fit in systems built to those specifications. Its compact overall length of 0.95 inches allows installation in tight spaces without sacrificing thread engagement or flare seating integrity.

Key Features

• 45-degree flare end conforms to SAE J512 and SAE J513 standards
• Flare x FNPTF end connection for inline tube-to-port assembly
• Rated to 1900 psi maximum working pressure
• Rated to 250 degrees F maximum working temperature
• Compact 0.95-inch overall length for tight-clearance installations
• UL Listed construction in brass for corrosion resistance in fluid service

Compatibility

Designed as an OEM-style replacement or service fitting for fluid and pneumatic line assemblies using 3/16-inch OD tubing with a 1/8-27 NPTF female port connection and a 45-degree SAE flare interface.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or refrigeration mechanic familiar with flared tube fittings and NPTF thread standards. Depressurize and drain the system completely before removing or installing any fittings. Use a calibrated flaring tool to produce a clean, uniform 45-degree flare on the tube end — an improperly formed flare is the leading cause of leaks at this connection type. Thread sealant compatible with NPTF fittings may be applied to the male NPT threads on the mating component, but never apply sealant to the flare seating surfaces.
