Eliminate seepage of refrigerants, cracking, splitting.
Forgings provide freedom from internal stress and a high tensile strength.
Straight fittings made from stress relieved bar stock. Prevents distorting the body when assembling-speeds up work materially.

Dryseal threads give tighter joint with less chance of leakage.
