The bellows heat resistance high pressure hydraulic fittings

Lou Cancel ordinary spring seal unit medium and the temperature of the ring seal to greatly expand the use of Teflon-coated rubber and other organic compounds, these in some media binding medium body,valve block
 the occurrence of chemical reactions of organic compounds generated is usually ordinary ring sealing unit sealing material in the low and high temperatures to change their physical properties, which is the hardening of the sealing bellows fail, instead of the above factors limit is usually applied as benzene, ketones, olefins, paraffins and ships oil, acid, alkali metal salts many other media, temperature range from -250 degrees to -450 degrees, carefully selected for heat welding and repair process, which is required for metal bellows.hose adapters
