Complete overview of the range of products including fittings and filters, various series of valves, hoses and quick-connects. Each category shows detailed subcategories and a direct link to the product literature including all technical data. Primary partner of SISON is the since 1998 recognized producer FITOK, well known for proven quality of selfdeveloped products following international standards.
Instrumentation Products of FITOK offer a number of advantageous technical details. E.g. the limits for alloy components in Stainless Steel 316 (1.4401). To improve corrosion resistance FITOK limits the content of Chrome between 17-18%. ASTM A479 allows 16-18%. 12-14% Nickel content compared to 10-14% according to ASTM A479 improves Hydrogen embrittlement resistance considerably. Also FITOK does limit content of Carbon between 0,04 and 0,055%. ASTM just determines less or equal 0,08%. Because of this specific and tight range of Carbon content corrosion resistance is much better.
