Simplex 3 tier gaskets (pack of 100)
Note: These gaskets are made of solid cork and are .060" thick. This is the ORIGINAL thickness. Beware of others selling thinner gaskets. There will be a chance of not sealing properly. When removing old gaskets, they measure 1/32" thick but was compressed to this thickness from installation. If you install a 1/32" gasket, after it compresses you will be lucky to have a good seal. The mounting surface and pneumatic must be 100% flat in which isn't always the case.
Having a .060" thick gasket insures a tight seal after compression and will compensate any pneumatic or mounting surfaces that might be slightly warped or not completely flat.
