Conventional flaring tools can be used when the work process is changed.
(change of work process)
Previously, a pipe extension margin of 0 to 0.5mm was provided for flaring. For R-410A air
conditioners, perform pipe flaring with a pipe extension margin of 1.0 to 1.5mm
.
(For clutch type only)
Conventional tool with pipe extension margin adjustment can be used.
