The YELLOW JACKET 60203 is a double flaring adapter designed for use in refrigeration and HVAC tubing work. This adapter allows technicians to create double flares on soft copper and aluminum tubing, producing a stronger, leak-resistant flare joint compared to single-flare connections. Double flaring is commonly required by code on brake and fuel lines as well as certain refrigeration and HVAC applications where joint integrity is critical. The 60203 is a hand-tool accessory used alongside a standard flaring bar or flaring tool block.
This adapter is suited for HVAC technicians, refrigeration mechanics, and plumbers working with soft copper tubing in residential and light commercial systems. It is used when a double flare is required for pressure-rated connections in refrigerant lines, fuel lines, or similar tubing assemblies. The adapter fits into a standard flaring tool setup to perform the first-stage upset before the final flare is formed.
Designed as an OEM-style accessory adapter for use with standard double flaring tool sets in HVAC and refrigeration tubing applications.
This adapter is used by licensed HVAC technicians and refrigeration mechanics performing tubing flare work. Always ensure the tubing is properly deburred and cleaned before flaring to avoid a compromised seal. Follow applicable mechanical codes for required flare type based on tubing material and system application. No power source is required for this hand-tool accessory.
