Teadit 1081 Ring Gasket

Ring gaskets are a flat sealing element, consisting of an inner and outer diameter sized to fit a flange's bore and bolt circle. Ring gaskets sit inside the flange's bolt circle. ASME B16.21 and ASME B16.47 govern the dimensions of ring gaskets for standard and large diameter pipe flanges. Teadit NA 1081 is a premium compressed fiber sheet gasket material produced from a combination of DuPont Kevlar, Inorganic Fillers and bonded with Nitrile Rubber (NBR). It is manufactured under rigorous quality control standards that are registered under ISO-9001 certification. NA 1081 has numerous applications in the process industries handling media like: mild acids and alkalis, water, hydrocarbons, oils, gasoline, steam, air, industrial gases, general chemicals, neutral solutions.
