PTFE*: (-180°C to +200°C) very stiff and very good chemical resistance (install carefully). Resistant against almost all chemicals, even at high temperatures, NBR / PTFE: (-10°C to +80°C) elastic and with very good chemical resistance, FKM / PTFE: (-20°C to +180°C) elastic and with very good chemical resistance,
*Not recommended as very stiff, small nominal widths are difficult to assemble!
