Parker 43F-12-12 Brass Flare to Solder Fitting 3/4 in

Product Description

The PARKER 43F-12-12 is a brass flare-to-solder tube fitting designed for use in refrigeration, HVAC, and plumbing systems where a 45-degree flared tube connection must transition to a soldered joint. Machined from brass, this fitting handles a maximum working pressure of 550 psi and a maximum working temperature of 250 degrees F, making it suitable for demanding fluid and refrigerant service. The 3/4-inch tube OD flare end uses a 1-1/16-14 UNF thread, and the solder end accepts standard copper tubing. Overall length is 2.04 inches and the unit weighs 0.24 pounds.

This fitting is used in residential and light commercial HVAC, refrigeration, and plumbing installations where a flared copper tube must be joined to a soldered copper line. Common applications include refrigerant line connections, chilled-water piping, and general fluid-service assemblies. It is typically installed by licensed HVAC technicians, refrigeration mechanics, and plumbers working on copper tube systems that require a leak-tight, code-compliant flare-to-solder transition.

Key Features

• 45-degree flare angle per SAE J512 and SAE J513 standards
• Brass construction for corrosion resistance in refrigerant and fluid service
• Maximum working pressure of 550 psi
• Maximum working temperature of 250 degrees F (121 degrees C)
• 1-1/16-14 UNF thread on the flare end
• UL Listed; meets SAE J512 and SAE J513 standards

Compatibility

Designed as an OEM-style replacement or service fitting for copper tube systems requiring a 3/4-inch OD 45-degree flare-to-solder connection in HVAC, refrigeration, and plumbing applications.

Installation Notes

Installation should be performed by a qualified HVAC technician, refrigeration mechanic, or licensed plumber. Isolate and recover any refrigerant or depressurize the fluid system fully before disassembling existing fittings. Use the appropriate flaring tool to prepare the tube end to a proper 45-degree flare before tightening; overtightening can crack the flare. The solder end should be cleaned, fluxed, and soldered in accordance with applicable codes such as ASHRAE 15 or the International Plumbing Code.
