Parker 48IFHD-4-2 Brass Inverted Male Flare Connector

Product Description

The PARKER 48IFHD-4-2 is a brass inverted male flare connector designed to join 1/4-inch OD flared tubing to a 1/8-27 NPTF male threaded port. The fitting features a flare-by-MNPTF end configuration, allowing a direct, leak-resistant connection between soft metal tubing and a female tapered pipe thread port. At 0.74 inches overall length and rated to 1,400 psi maximum working pressure, it handles demanding service conditions in hydraulic, refrigeration, and fuel line applications. Plumbers, HVAC technicians, and fluid-system mechanics install this fitting wherever a compact, high-integrity flare-to-pipe transition is required.

This connector is suited for residential and light commercial systems where 1/4-inch OD flared tubing meets a 1/8-27 NPTF female port. Typical installation scenarios include refrigerant line connections, low-pressure hydraulic circuits, fuel lines, and compressed-air fittings. The NPTF thread standard provides a pressure-tight mechanical seal without relying solely on thread sealant. Maximum working temperature is 250 degrees F, making it appropriate for a wide range of fluid and gas service environments encountered in trade work.

Key Features

• Brass construction provides corrosion resistance and compatibility with a broad range of fluids and gases
• 1,400 psi maximum working pressure rating for demanding service conditions
• Flare x MNPTF end connection for a secure, leak-resistant tube-to-pipe transition
• 1/4-inch tube OD with 1/8-27 NPTF thread meets SAE J51 standards
• UL Listed for additional assurance in code-required installations
• Compact 0.74-inch overall length suits tight-clearance installations

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4-inch OD flared tubing terminating at a 1/8-27 NPTF female port in refrigeration, hydraulic, fuel, or compressed-air applications.

Installation Notes

This fitting is installed by qualified HVAC technicians, plumbers, or fluid-systems mechanics. Before installation, depressurize and isolate the system completely and verify the mating port is a true NPTF thread to ensure a pressure-tight seal. Use appropriate flaring tools to produce a clean, uniform flare on the tubing end before tightening. Follow applicable SAE, NEC, or IFGC guidelines as required by the system type and local code.
