MEDIAMAXIMUM TEMPERATUREAPPLICATIONS
N – Natural Cotton300°F
150°C		Same (non-FDA) applications as bleached cotton.
C – Bleached Cotton FDA300°F
150°C		For potable liquids, vegetable oils, beverages, organic solvents, water, dilute acids, petroleum oils and other services.
P – Polyester250°F
121°C		Chemical compatibility similar to cotton and polypropylene. Has a higher temperature resistance than polypropylene in most cases.
E – Polypropylene180°F
82°C		Filtration of organic acids, alkalis, solvents and many other chemicals. Very effective in low viscosity solutions.
S – Polypropylene FDA180°F
82°C		Same chemical compatibility as polypropylene but complies with FDA regulations that permits contact with food and edible products.
R – Rayon300°F
150°C		Chemical compatibility similar to cotton. Used primarily in filtration of petroleum oils.
CAPS & CORESMAXIMUM TEMPERATURECHARACTERISTICS
S – Tinned Steel375°F
191°C		General purpose applications
P – Polypropylene FDA180°F
82°C		For lower temperature applications of corrosive fluids and gases. Easily incinerated to a trace of ash.
4 – 304 Stainless Steel750°F
399°C		For high temperature dilute acids and moderately corrosive fluids.
6 – 316 Stainless Steel750°F
399°C		For high temperature applications and highly corrosive fluids.
GASKETS & O-RINGSMAXIMUM TEMPERATURECHARACTERISTICS
B – Buna300°F
149°C		Very good resistance to water, alkalis and many acids. Poor resistance to oils, gasoline and most solvents (except oxygenated).
V – Viton450°F
232°C		Can be used at high temperature with many fuels, lubricants, hydraulic fluids and solvents.
T – Teflon500°F
260°C		Excellent resistance to almost all chemicals and solvents. Good heat resistance, exceptionally good low-temperature properties.
S – Silicone600°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 – Neoprene250°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 – EPDM300°F
149°C		Very good water resistance. Excellent resistance to oils and gasoline. Fair to good resistance to acids and alkalis.
