PRODUCT SPECIFICATIONS

Media Maximum Temperature Applications
N – Natural Cotton 300°F / 150°C Same (non-FDA) applications as bleached cotton.
C – Bleached Cotton FDA 300°F / 150°C For potable liquids, vegetable oils, beverages, organic solvents, water, dilute acids, petroleum oils and other services.
P – Polyester 250°F / 121°C Chemical compatibility similar to cotton and polypropylene. 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 permits 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 & Cores Maximum Temperature Characteristics
E – 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 applications
4 – 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-Rings Maximum Temperature Characteristics
B – 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.
