VALQUA No. 6500
Compressed Non-Asbestos Fiber Sheet for general use
Compressed Non-Asbestos Fiber Sheets are rolled and vulcanized sheet type gasket materials,
in which special rubber binders and a small amount of filler material are mixed with organic and inorganic fibers.
These are suitable to be used as Non-asbestos gaskets for pipe flanges and equipment in various industries.
The adaptability of these sheets for water apparatus has been confirmed based on JIS S 3200-7.
