Parker 46IFHD-4-2 Brass Inverted Female Flare Connector

Product Description

The PARKER 46IFHD-4-2 is a brass inverted female flare connector designed for flared tube-to-threaded port connections in fluid and pneumatic systems. It accepts a 1/4 inch OD flared tube on one end and connects to a 1/8-27 NPTF female port on the other end, providing a leak-resistant mechanical seal. Rated to 1400 psi maximum working pressure and suitable for temperatures up to 250 degrees F, this fitting is built for demanding service in hydraulic, refrigeration, and instrumentation lines. Licensed plumbers, HVAC technicians, and pipefitters install this type of connector when transitioning from a flared tube run to a threaded equipment port.

This connector is appropriate for residential and light commercial applications where SAE J51 flared tube fittings interface with NPTF-threaded ports on valves, manifolds, compressors, or equipment panels. Its compact overall length of 0.78 inches suits installations with limited clearance. The UL Listed rating supports use in systems requiring third-party certification. It is sold individually and is a direct-catalog Parker fitting for use in refrigeration, air conditioning, fuel, and hydraulic lines within approved pressure and temperature limits.

Key Features

• Flare x FNPTF end connections for tube-to-threaded-port transitions
• 1400 psi maximum working pressure for high-pressure fluid and pneumatic service
• 250 degrees F maximum working temperature
• Brass construction for corrosion resistance in refrigerant, fuel, and hydraulic media
• Meets SAE J51 and is UL Listed
• Compact at 0.78 inches overall length for tight-clearance installations

Compatibility

Designed for use with 1/4 inch OD flared tubing connecting to 1/8-27 NPTF threaded ports in refrigeration, HVAC, hydraulic, and instrumentation systems per SAE J51 specifications.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or pipefitter familiar with flared tube and NPTF threaded connections. De-energize and depressurize the system completely before removing or installing any fitting. Use appropriately sized flaring tools to ensure a proper tube flare seat; a poor flare is the leading cause of joint leakage. Thread engagement should follow standard NPTF practice — do not overtighten, as brass fittings are susceptible to thread damage.
