Flare and Union Dimensions Tab.
NOTE: Make sure that the oil used to lubricate the flare is the same type or
compatible with the oil used in the refrigerating circuit.
The following results are obtained if flaring has been carried out correctly
(Fig.9):
- Smooth and mirrored surfaces.
- Smooth edges.
- Flared sides of uniform length.
N.B.: Take care to prevent swarf, dust or other impurities from dropping inside
the pipes since these would clog the cooling circuit at the capillary, causing the
system to block or the compressor to seize.
