Seals | Lubrication | Leak Detection | Filters/Screens | Flushing
ACDelco recommends replacing O-rings and seal washers during joint service. The majority of ACDelco replacement parts come with the necessary seals required to complete a professional repair.
When new O-rings are installed, it is recommended that both the O-ring and the threaded joint be lubricated with mineral oil. This maintains the seal’s ability to properly seat as well as prevents corrosion of the joint thread. (Note: PAG oil is hydroscopic and may cause joint threads to corrode.)
