Parker 43F-10-12 Brass Flare to Solder Fitting 5/8 in

Product Description

The PARKER 43F-10-12 is a brass flare-to-solder fitting designed to connect a flared tube to a solder-joint copper fitting in refrigeration, HVAC, and fluid-handling systems. It features a 5/8-inch tube outside diameter on the flare end and a 7/8-14 UNF thread, with a standard 45-degree flare angle. The reduced outside diameter on the solder end measures 3/4 inch. Machined from brass, this fitting provides reliable sealing at the flare interface and a leak-free solder joint on the mating side. HVAC technicians and refrigeration mechanics use this type of fitting when transitioning between flared tubing and sweat-connected components.

This fitting is suited for residential and light commercial HVAC and refrigeration applications where copper tubing with a 45-degree SAE flare must connect to a brazed or soldered copper line or component. Typical install scenarios include refrigerant line sets, ACR copper tubing assemblies, and hydronic or fluid-transfer piping where a flare-to-sweat transition is required. The compact brass construction keeps the fitting lightweight at 0.14 pounds, making it easy to work with in tight mechanical spaces.

Key Features

• 45-degree SAE flare angle for standard ACR and refrigeration tubing connections
• 5/8-inch tube OD flare end with 7/8-14 UNF thread
• 3/4-inch reduced OD solder end for sweat connection to copper fittings
• Brass construction for corrosion resistance and machinability
• Lightweight at 0.14 pounds, suitable for confined installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and fluid-handling systems that use 5/8-inch OD flared copper tubing with a 45-degree SAE flare and require a solder-joint transition.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic. Recover and isolate any refrigerant or fluid pressure from the system before disassembling existing fittings. The flare end requires a properly formed 45-degree flare on the tube; inspect the flare seat for cracks or deformation before torquing the fitting. The solder end must be cleaned, fluxed, and brazed or soldered in accordance with applicable mechanical codes and the system fluid requirements.
