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