You need to inspect the new O-ring seal for any signs or cracks, cuts, or damage, remove the cap or tape from the A/C refrigerant components, use a lint-free clean, dry cloth to clean the sealing surfaces of the A/C refrigerant components, lightly coat the new O-ring seal with mineral base 525 viscosity refrigerant oil, carefully slide the new O-ring seal onto the A/C refrigerant component and assemble the A/C components.
