Parker 48IFHD-6-2 Brass Inverted Male Flare Connector

Product Description

The PARKER 48IFHD-6-2 is a brass inverted male flare connector designed to join a 3/8-inch OD flared tube to a 1/8-27 NPTF male threaded port. The fitting features a Flare x MNPTF end configuration, providing a secure, leak-resistant connection in hydraulic, fuel, and fluid transfer lines. Machined from brass, this connector resists corrosion and tolerates the vibration common in mobile equipment and stationary fluid systems. It is sized and threaded to Parker standards, making it a direct-specification fitting for applications that require inverted flare sealing at small-diameter connections. Licensed plumbers, HVAC technicians, and hydraulic system installers are the primary users of this fitting type.

This connector is suited for residential and light commercial fluid systems where a 3/8-inch inverted flare tube must terminate at a 1/8-27 NPTF port. Common install scenarios include refrigeration line sets, fuel delivery systems, hydraulic control circuits, and low-pressure pneumatic assemblies. The 1/8-27 NPTF thread size is a common port size on valves, manifolds, and pump bodies across these system types. The inverted flare seat provides a metal-to-metal seal that eliminates the need for thread sealant at the tube end.

Key Features

• Brass construction for corrosion resistance in fuel, refrigerant, and fluid service
• 3/8-inch tube OD inverted flare end accepts standard flared tubing
• 1/8-27 NPTF male thread provides a pressure-tight port connection
• Flare x MNPTF configuration supports tube-to-body transitions
• Metal-to-metal flare seat reduces leak points without supplemental sealant
• Compact form factor suits tight installation spaces on valves and manifolds

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8-inch OD inverted flare tubing with 1/8-27 NPTF ported components.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. De-energize and depressurize the system fully before disconnecting or installing any fittings. Ensure the tube end is properly flared to the inverted flare specification before seating the fitting; an improperly formed flare is the most common cause of leaks at this joint type. Verify thread engagement is sufficient and do not overtighten, as brass threads can deform under excessive torque.
