FLUIDX offers a range of L gaskets for use with cylindrical and bell jar vacuum chambers. The L gasket named for its "L" shape creates a tight seal between the chamber and lid. Both flat profile or o-ring profile gaskets styles are available. Sizes are based on the vacuum chamber cylindrical diameter.
Slightly lubricate the L gaskets with a silicone vacuum grease such as the Dow Corning silicone grease to improve the sealing capability. Use FLUIDX metal band clamps to secure or hold L-gaskets into place.
