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

Product Description

The PARKER 43F-10-8 is a brass flare-to-solder tube fitting designed to connect a 45-degree flared tube end to a solder-joint copper line. It features a 5/8 inch tube outside diameter on the flare end and a 7/8-14 UNF thread. The reduced outside diameter on the solder end measures 1/2 inch. Constructed from brass, this fitting provides reliable sealing in refrigeration, HVAC, and plumbing systems where a transition from flared tubing to a soldered connection is required. Installation is performed by licensed HVAC technicians or plumbers working on refrigerant lines, ACR copper tubing, or similar fluid-handling systems.

This fitting is suited for residential and light commercial HVAC and refrigeration applications where 45-degree flare connections transition to sweat-soldered copper piping. Typical install scenarios include service valve connections, refrigerant line repairs, and ACR tubing assemblies where a flared tube must terminate at a solder-cup fitting. The 7/8-14 UNF thread standard is common in refrigeration-grade components and pairs with standard SAE flare nuts of the corresponding size.

Key Features

• 45-degree flare angle conforms to SAE standard flare geometry for leak-free refrigerant and fluid connections
• 5/8 inch tube OD on the flare end accommodates common ACR and plumbing copper tubing sizes
• 7/8-14 UNF thread provides a precise, secure flare-nut engagement
• 1/2 inch reduced OD on the solder end accepts standard sweat-joint fittings and copper couplings
• Brass construction resists corrosion and withstands typical refrigeration and plumbing system pressures and temperatures

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and plumbing systems using 5/8 inch OD flared copper tubing with 45-degree SAE flare geometry and 7/8-14 UNF flare nuts.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Recover all refrigerant and depressurize the system before disconnecting or installing flare fittings in refrigerant circuits. Ensure the copper tube end is properly deburred and flared to the correct 45-degree angle before tightening the flare nut to avoid seat damage or leaks. For the solder end, use appropriate flux and silver-bearing or lead-free solder per local plumbing and mechanical codes.
