Replacing the Chamber Cap O-Ring

Fine fibers and particles between the O-ring and its sealing surfaces can cause leaks, as can
scratches or cuts in the O-ring or in the metal surfaces. When it is necessary to replace the
O-ring, follow these steps.

1.

Using a pointed tool, carefully remove the O-ring from its groove in the cap. A small
niche is provided at the groove for placement of the tool.

2.

Clean the groove in the chamber cap using a small brush or lint-free tissue moistened
with isopropyl alcohol.

3.

Allow the chamber cap to dry thoroughly.

4.

Place a small amount of Dow Corning High vacuum grease (or equivalent) on your index
finger. Touch your thumb with your index finger to place grease on both fingers.

Be careful not to scratch the metal surface of the chamber cap. Scratches could result
in an imperfect seal.

Apply the grease sparingly; too much grease may alter cell volume, while too little
grease results in an imperfect seal and leaks.
