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. 18 -"):
- Smooth and mirrored surfaces.
- Smooth edges.
- Flared sides of uniform length.
Note: 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.
