Has a higher temperature resistance than polypropylene in most cases.E – Polypropylene 180°F / 82°C Filtration of organic acids, alkalis, solvents and many other chemicals. Very effective in low viscosity solutions.S – Polypropylene FDA 180°F / 82°C Same chemical compatibility as polypropylene but complies with FDA regulations that permit contact with food and edible products.R – Rayon 300°F / 150°C Chemical compatibility similar to cotton. Used primarily in filtration of petroleum oils.Caps & CoresMaximum Temperature CharacteristicsE – Polypropylene FDA 180°F / 82°C For lower temperature applications of corrosive fluids and gases. Easily incinerated to a trace of ash.S – Tinned Steel 375°F / 191°C General purpose applications4 – 304 Stainless Steel 750°F / 399°C For high temperature dilute acids and moderately corrosive fluids.6 – 316 Stainless Steel 750°F / 399°C For high temperature applications and highly corrosive fluids.Gaskets & O-RingsMaximum Temperature CharacteristicsB – Buna 300°F / 149°C Very good resistance to water, alkalis and many acids. Poor resistance to oils, gasoline and most solvents (except oxygenated).V – Viton® 450°F / 232°C Can be used at high temperature with many fuels, lubricants, hydraulic fluids and solvents.T – Teflon® 500°F / 260°C Excellent resistance to almost all chemicals and solvents. Good heat resistance, exceptionally good low-temperature properties.S – Silicone 600°F / 316°C Excellent heat resistance. Fair water resistance, poor resistance to steam at high pressures. Fan to good acid and alkali resistance, poor resistance to oils and solvents.N – Neoprene 250°F / 121°C Good resistance to non-aromatic petroleum, fatty oils, solvents (except aromatic, chlorinated or ketone types). Good water and alkali resistance, fair acid resistance.E – EPDM 300°F / 149°C Very good water resistance. Excellent resistance to oils and gasoline. Fair to good resistance to acids and alkalis.Available End Caps
