Dimensions Related To Flare Processing For R410A / R22; Flare And Flare Nut Dimensions For R410A; Flare And Flare Nut Dimensions For R22 - Toshiba Carrier RAV-SP180AT2-UL Service Manual

c) Insertion of Flare Nut
d) Flare Processing
Make certain that a clamp bar and copper pipe have been cleaned.
By means of the clamp bar, perform the flare processing correctly.
Use either a flare tool for R410A or conventional flare tool.
Flare processing dimensions differ according
to the type of flare tool.
When using a conventional flare tool, be sure
to secure "dimension A" by using a gauge for
size adjustment.
