Parker 43F-4-4 Brass Flare to Solder Fitting 1/4 in

Product Description

The PARKER 43F-4-4 is a brass flare-to-solder tube fitting designed for use in refrigeration, HVAC, and plumbing systems where a 45-degree flared connection meets a soldered line. It accepts a 1/4-inch tube OD on the flare end with a 7/16-20 UNF thread, and transitions to a solder-cup end for copper tubing connections. Rated to 1400 psi maximum working pressure and 250 degrees F maximum working temperature, this fitting handles the demands of refrigerant lines, fuel lines, and compressed fluid systems. At 0.98 inches overall length and 0.02 pounds, it is compact enough for tight installations. Licensed HVAC technicians, refrigeration mechanics, and plumbers are the primary installers.

This fitting is suited for residential and light commercial HVAC systems, refrigeration equipment, and hydraulic or pneumatic tubing assemblies that require a leak-free flare connection on one end and a soldered joint on the other. It is commonly installed at service valves, coil connections, and anywhere a flared tube must transition to a brazed or soldered copper line. The 45-degree flare angle conforms to SAE J512 and SAE J513 standards, making it appropriate for standard SAE flare fittings used throughout the trade.

Key Features

• 250 degrees F maximum working temperature
• UL Listed; meets SAE J512, SAE J513 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard SAE 45-degree flare tube systems using 1/4-inch OD tubing in HVAC, refrigeration, and plumbing applications.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or plumber. Recover all refrigerant and depressurize the system fully before removing or installing any fittings. The flare end requires a properly formed 45-degree flare on the tubing; use a calibrated flaring tool to ensure a leak-free seat. The solder end should be cleaned, fluxed, and brazed or soldered per applicable codes including ASHRAE and local mechanical code requirements.
