Important  : Flat washer type seals do not require lubrication.

  1. Inspect the new seal washer for any signs of cracks, cuts, or damage.
  2. Do not use a damaged seal washer.
  3. Remove the cap or tape from the A/C refrigerant components.
  4. Using a lint-free clean, dry cloth, clean the sealing surfaces of the A/C refrigerant components.
  5. Carefully install the new seal washer onto the A/C refrigerant component.

    The washer must completely bottom against the surface of the fitting.

    Important  : After tightening the A/C components, there should be a slight sealing washer gap of approximately 1.2 mm (3/64 in) between the A/C line and the A/C component.

  6. Assemble the remaining A/C refrigerant components. Refer to the appropriate repair procedure.
