Air conditioning O-ring seals should be coated with 525 viscosity refrigerant oil just before installation and should be slipped onto the flange tube to
ensure proper locating and sealing. To prevent the possibility of swelling and a reduction in sealing effectiveness, O-ring seals should not be soaked in
refrigerant oil. Before installation, O-ring seals and fittings should be examined to insure they have not been nicked or deformed. Replace nicked or
deformed parts to prevent refrigerant leakage.
