ASKETS

Gaskets are non-warranty, high-wear consumable items subject to compression forces, heat,
and outgassed byproducts. Heavy usage rates may necessitate frequent replacements. The
manufacturer strongly recommends keeping a spare gasket on hand during operation.

Each oven comes with a replaceable silicon gasket installed on the chamber liner. This
gasket seals against the chamber door to maintain the vacuum integrity of the chamber. The
gasket must be replaced periodically and is rated to 230°C. It is vulnerable to acids and
solvents. The manufacturer also offers for sale

Viton®,

fluorosilicone, and Buna gaskets. See

page 70 for information on gasket type suitability for baking applications.

These ovens do not require vacuum grease.
