Parker 43F-12-14 Brass Flare to Solder Fitting 3/4 in

Product Description

The PARKER 43F-12-14 is a brass flare-to-solder fitting designed to transition a 45-degree flared tube connection to a soldered joint in refrigeration, HVAC, and plumbing systems. The fitting accepts a 3/4-inch tube OD on the flare end and uses a 1-1/16-14 UNF thread for a secure, leak-resistant mechanical connection. The solder end accommodates a 7/8-inch reduced outside diameter for standard sweat connections. Constructed entirely from brass, this fitting delivers good corrosion resistance in both wet and refrigerant-service environments. Licensed HVAC technicians and plumbers install this type of fitting when connecting copper tubing assemblies that require a flare-to-sweat transition point in a refrigerant or fluid circuit.

This fitting is suited for residential and light commercial HVAC, refrigeration, and plumbing applications where a 45-degree SAE flare connection must be joined to a copper sweat line. Typical install scenarios include line-set connections, service valve piping, and condensate or fluid-line transitions. The 1-1/16-14 UNF thread size is common in larger-capacity refrigerant service connections. The fitting weighs approximately 0.09 pounds and ships individually, making it a practical replacement or repair component for field service work.

Key Features

• Brass construction provides corrosion resistance for refrigerant and plumbing service
• 45-degree flare angle conforms to SAE flare standards for secure, leak-resistant joints
• 3/4-inch tube OD flare end suits common larger-diameter copper tubing
• 1-1/16-14 UNF thread ensures compatibility with standard SAE flare fittings
• 7/8-inch reduced OD solder end designed for standard sweat-joint copper connections
• Lightweight at 0.09 pounds, convenient for field carry and inventory

Compatibility

Designed as an OEM-style replacement or field-service fitting for systems requiring a 45-degree SAE flare-to-solder transition at 3/4-inch tube OD with 1-1/16-14 UNF thread.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Depressurize and recover any refrigerant from the system before disconnecting existing fittings, in accordance with EPA Section 608 regulations. Use a properly sized flaring tool to prepare the tube end before threading the flare nut; over-tightening the flare connection can crack the fitting seat. Sweat the solder end using standard copper-to-copper soldering techniques and appropriate flux, following applicable local mechanical codes.
