You can inspect the new O-ring seal for signs of damage, remove the cap or tape from the A/C refrigerant components, clean the sealing surfaces of the A/C refrigerant components, coat the new O-ring seal with mineral base 525 viscosity refrigerant oil, slide the new O-ring seal onto the A/C refrigerant component, fully seat the O-ring seal and assemble the A/C components.
