Parker 48IFHD-6-6 Brass Inverted Male Flare Connector

Product Description

The PARKER 48IFHD-6-6 is a brass inverted male flare connector designed to join flared tubing to male NPTF threaded ports in hydraulic and fluid system applications. It features a 3/8 inch tube OD flare end and a 3/8-18 NPTF male threaded end, providing a reliable leak-resistant connection in a compact one-piece fitting. Rated to 1000 psi maximum working pressure and up to 250 degrees F, this connector handles demanding service conditions. It is installed by licensed plumbers, HVAC technicians, and fluid power mechanics working on refrigeration, hydraulic, or fuel system lines where an inverted flare-to-pipe thread transition is required.

This fitting is suited for residential and light commercial applications involving copper or steel flared tubing connected to threaded component ports. Typical install scenarios include fuel delivery systems, hydraulic control lines, refrigeration piping, and compressed air or fluid circuits where SAE J51 inverted flare geometry is specified. The NPTF thread form provides a dry-seal mechanical connection without requiring additional sealant tape on the threads.

Key Features

• Inverted male flare end accepts 3/8 inch tube OD per SAE J51 geometry
• 3/8-18 NPTF male thread delivers a dry-seal port connection
• 1000 psi maximum working pressure for demanding fluid system service
• 250 degrees F maximum working temperature rating
• Brass construction resists corrosion in fuel, refrigerant, and hydraulic media
• UL Listed and SAE J51 compliant

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using SAE J51 inverted flare connections with 3/8 inch tube OD and 3/8-18 NPTF male threaded port interfaces.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or fluid power mechanic. Depressurize and isolate the system completely before removing or installing any fittings. Ensure mating tubing is properly flared to SAE J51 specifications before tightening the fitting to avoid deforming the flare seat. The NPTF dry-seal thread is designed to make a pressure-tight connection on thread engagement alone, but inspect all connections for leaks after returning the system to service.
