vacuum check port cap (C) to expose the O-ring. Clean both O-rings and opposing contact surfaces using
a slightly dampened lint-free cloth. Replace the O-rings if damaged or every year. The SportDiver Spare
O-ring Set (Item SL40010) includes the main O-ring and vacuum check port O-ring.
5. Put a small dab of silicone O-ring on your fingertip. Apply a thin film of silicone lube to the exposed surface
of the main O-ring and vacuum check port O-ring. Use your fingertip to evenly spread the lube over the
exposed O-ring surfaces. Only a thin film of lube is necessary.
