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

Product Description

The PARKER 43F-10-10 is a brass flare-to-solder tube fitting designed to connect a 45-degree flared tube end to a soldered copper line. It features a 5/8 inch tube outside diameter, a 7/8-14 UNF thread size, and a 45-degree flare angle conforming to SAE J512 and SAE J513 standards. The fitting is rated for a maximum working pressure of 650 psi and a maximum working temperature of 250 degrees F, making it well-suited for refrigeration, HVAC, and plumbing systems that use flare-to-sweat transitions. Licensed HVAC technicians and plumbers install this fitting when connecting flared copper tubing to a soldered joint in a sealed system.

This fitting is commonly used in residential and light commercial HVAC and refrigeration systems where a transition from a flared tube connection to a soldered copper fitting is required. It is appropriate for applications involving copper tubing in suction, liquid, and service line configurations. The compact overall length of 1.73 inches suits tight installation spaces in equipment cabinets, line sets, and service valve assemblies. It carries a UL Listing, supporting use in code-governed mechanical installations.

Key Features

• 45-degree flare angle meets SAE J512 and SAE J513 standards
• Flare-to-solder end connection allows direct transition from flared tubing to soldered copper
• Rated to 650 psi maximum working pressure for use in pressurized refrigerant and fluid lines
• Maximum working temperature of 250 degrees F suitable for typical HVAC and refrigeration operating ranges
• Brass construction provides corrosion resistance and reliable sealing at the flare seat
• UL Listed for use in installations subject to code compliance requirements

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Recover all refrigerant and depressurize the system before removing or installing any flare fitting. The solder end requires standard sweat-soldering technique with appropriate flux and solder per applicable mechanical codes. Do not overtighten the flare nut, as excess torque can crack the flare seat or distort the flare cone.
