3R865

Compressed sheets

Compressed non-asbestos sheet gasket material produced from a combination of aramid and other synthetic fibers and bonded with nitrile rubber (NBR). It is an efficient material that is recommended in the fabrication of seals in ndustrial processes and in the water/wastewater industry. It is also commonly used in equipment such as valves and pumps.
