Parker 43F-8-10 Brass Flare to Solder Fitting 1/2 in Od

Product Description

The PARKER 43F-8-10 is a brass flare-to-solder tube fitting designed for use in refrigeration, HVAC, and fluid-system piping where a 45-degree SAE flare connection must transition to a soldered copper tube end. Machined from brass, it accepts a 1/2 inch tube OD on the flare end with a 3/4-16 UNF thread and connects to a 5/8 inch reduced outside diameter solder cup on the opposite end. Rated to 750 psi maximum working pressure and 250 degrees F, this fitting handles the demanding conditions found in refrigerant lines, hydraulic-assist circuits, and compressed-gas distribution systems. It is installed by HVAC technicians, refrigeration mechanics, and licensed plumbers during new construction and service work.

This fitting is suited for residential and light commercial HVAC and refrigeration applications where a flared tube line must tie into a sweated copper assembly. Typical scenarios include connecting factory-flared refrigerant line sets to soldered manifold headers, tying into copper distribution piping during system retrofits, or fabricating custom line assemblies on rooftop and split-system equipment. The 45-degree flare angle conforms to SAE J512 and SAE J513 standards, making it compatible with standard SAE flare fittings and tools common across the refrigeration and HVAC trades.

Key Features

• 45-degree SAE flare end conforms to SAE J512 and SAE J513 standards
• Brass construction resists corrosion in refrigerant and fluid-system environments
• 3/4-16 UNF thread mates with standard SAE flare nuts and fittings
• 750 psi maximum working pressure suits high-side refrigerant and compressed-gas lines
• Rated to 250 degrees F for use in elevated-temperature service conditions
• UL Listed fitting for code-compliant installations

Compatibility

Designed as a standard SAE 45-degree flare-to-solder adapter for use with 1/2 inch OD tubing in HVAC, refrigeration, and fluid-piping systems conforming to SAE J512 and SAE J513 flare specifications.

Installation Notes

Installation should be performed by a qualified HVAC technician, refrigeration mechanic, or licensed plumber. De-pressurize and recover any refrigerant or fluid from the system before beginning work. The flare end requires a properly formed 45-degree SAE flare; inspect the tube flare for cracks or deformation before tightening the flare nut. The solder cup end must be cleaned, fluxed, and sweated using accepted copper-brazing or soldering practices in accordance with applicable mechanical codes.
