LACO offers a wide range of Vacuum Chamber 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 buna, viton and silicon profiles or buna "ridge" profile gasket styles are available. Sizes are based on the vacuum chamber cylindrical outer diameter.
Slightly lubricate the L-gasket with a silicone vacuum grease such as Dow Corning silicone grease to improve the sealing capability. Use LACO's metal band clamps to secure or hold L-gaskets into place. Custom Size Buna L-gaskets can be quoted upon request.
