BUY FOR THE JOB
What to look for
- ✓Flare tooling approved for the tubing and refrigerant system being installed
- ✓Torque tools whose ranges place specified values comfortably inside their working span
- ✓Nitrogen regulation suited to pressure testing and low-flow brazing where applicable
- ✓A leak detector rated for the refrigerants you expect to encounter
- ✓A2L-compatible equipment whenever mildly flammable refrigerants are in scope
03
BEFORE YOU TRUST IT
Field-use checks
- 01Read the complete installation manual before choosing adapters or flare dimensions.
- 02Deburr without dropping debris into tubing and keep open lines capped.
- 03Use specified torque with a backup wrench; never judge a flare connection by feel alone.
- 04Pressure-test, leak-test, evacuate and commission using the exact model procedure.
04
RED FLAGS
What to avoid
- Universal torque guesses
- Reusing damaged flares or contaminated tubing
- Buying a kit that is incompatible with the refrigerant safety classification
