Parker 46IFHD-5-2 Brass Inverted Female Flare Connector

Product Description

The PARKER 46IFHD-5-2 is a brass inverted female flare connector designed for use in hydraulic and fluid system tubing assemblies. It features a flare-to-FNPTF end configuration, accepting a 5/16 inch tube OD on the flare end and a 1/8-27 NPTF threaded port on the female end. This connector creates a secure, leak-resistant joint in low- and medium-pressure tubing lines. It is typically installed by licensed plumbers, HVAC technicians, or fluid system mechanics working on refrigeration, hydraulic, or pneumatic systems where inverted flare fittings are the specified connection standard.

This connector suits residential and light commercial applications where 5/16 inch OD tubing terminates at a 1/8-27 NPTF female port on a valve, manifold, or component body. The inverted flare design is commonly found in brake, fuel, and refrigeration tubing runs where vibration resistance and a tight metal-to-metal seal are required. Brass construction provides corrosion resistance appropriate for water, air, refrigerant, and light hydraulic fluid service.

Key Features

• Inverted female flare fitting for secure metal-to-metal sealing without additional sealant on the flare end
• Flare x FNPTF end configuration connects 5/16 inch OD tubing to a 1/8-27 NPTF threaded port
• Brass construction offers corrosion resistance and compatibility with a broad range of fluids
• 1/8-27 NPTF thread standard provides a pressure-tight mechanical seal at the female port
• Compact single-piece body suits tight installation spaces in equipment and panel assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 5/16 inch OD inverted flare tubing and 1/8-27 NPTF female threaded ports in hydraulic, refrigeration, or pneumatic assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with flare fitting assembly procedures and applicable system codes. Before servicing, depressurize and isolate the tubing circuit completely. Inspect the flare seat and tube end for nicks or irregularities before assembly, as inverted flare connections rely on a clean metal-to-metal contact for a leak-free seal. Do not overtighten; snug to hand-tight and apply only the additional turns specified by the tubing system manufacturer or applicable standard.
