Parker 48IFHD-8-4 Brass Inverted Male Flare Connector

Product Description

The PARKER 48IFHD-8-4 is a brass inverted male flare connector designed to join a 1/2-inch OD flared tube to a male NPTF threaded port. The fitting features a Flare x MNPTF end configuration with a 1/4-18 thread size, rated for up to 750 psi working pressure and a maximum working temperature of 250 degrees F. At 1.07 inches overall length, it is a compact, single-piece fitting suited for use in hydraulic, refrigeration, and fluid-transfer line assemblies. Licensed plumbers, HVAC technicians, and fluid-power mechanics install this type of connector in both service and OEM applications.

This fitting is used in residential and light commercial systems where an inverted flare tube must terminate at a threaded port. Common applications include refrigerant line connections, hydraulic fittings, fuel systems, and other high-pressure fluid circuits requiring a leak-tight mechanical seal. The NPTF thread standard provides a pressure-tight seal through thread interference, reducing reliance on thread sealant in many installations. The brass construction resists corrosion in environments typical of HVAC and plumbing service work.

Compatibility

Designed for use with 1/2-inch OD inverted flare tubing terminating at a 1/4-18 NPTF male threaded port in hydraulic, refrigerant, fuel, or fluid-transfer systems.

Installation Notes

Installation should be performed by a qualified technician following applicable codes including IFGC or IPC where fluid or gas lines are involved. De-pressurize and isolate the line completely before removing or installing any fitting. NPTF threads are designed to seal through thread-form interference; inspect threads for damage before assembly and apply thread sealant only as required by the system specification. Do not over-torque, as brass fittings are subject to thread damage under excessive force.
