• Larger o-ring of correct thickness

• Razor Blade

• Super Glue

Measure for the O-ring, 1 of several ways:

-If the old one is available and not stretched or shrunken, use it for determining size
-If old one not available, cut open the new larger diameter one and lay it in place and mark with a pen.
-Use string to determine proper length

After marking the gasket material lay the ends together and cut the rubber material perfectly straight on both sides with a razor blade. The idea is to get both ends square.

After the material has been cut to size:

Place a small drop of superglue on the surface of one end then  place the two ends together and hold in place for a couple minutes.
