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

Product Description

The PARKER 43F-8-8 is a brass flare-to-solder tube fitting designed to connect a 45-degree SAE flared tube to a soldered copper line in refrigeration, HVAC, and fluid-handling systems. The fitting accepts a 1/2 inch OD tube on the flare end with a 3/4-16 UNF thread and transitions to a solder-cup end for a permanent sweat connection. It is rated for a maximum working pressure of 750 psi and a maximum working temperature of 250 degrees F, making it suitable for a wide range of refrigerant and fluid service applications. HVAC technicians and refrigeration mechanics are the primary installers of this type of fitting.

This fitting is used in residential and light commercial HVAC and refrigeration systems where a flared tube must transition to a soldered copper connection. Typical applications include refrigerant line sets, ACR tubing assemblies, and hydronic or fluid-transfer plumbing where a leak-free mechanical-to-brazed joint transition is required. The 45-degree flare angle conforms to SAE J512 and SAE J513 standards, which are commonly specified in refrigerant piping work. The compact 1.42 inch overall length suits tight-clearance installations in equipment cabinets and line sets.

Key Features

• 45-degree SAE flare end with 3/4-16 UNF thread for secure tube connection
• Solder-cup opposite end allows permanent sweat joint to copper tubing
• Brass construction resists corrosion in refrigerant and fluid service
• Rated to 750 psi maximum working pressure
• Rated to 250 degrees F maximum working temperature
• Meets SAE J512, SAE J513, and UL Listing standards

Compatibility

Designed as an OEM-style flare-to-solder transition fitting for 1/2 inch OD ACR and refrigerant tubing systems using 45-degree SAE flare connections per SAE J512 and SAE J513.

Installation Notes

Installation is typically performed by a licensed HVAC technician or refrigeration mechanic. De-pressurize and recover all refrigerant from the system before disturbing any flare or solder connections. Ensure the flare is properly formed and the mating tube end is clean, deburred, and dry before making the solder joint. Follow applicable mechanical codes and refrigerant-handling regulations when working on pressurized refrigerant systems.
