440 F75 Viton® O-Ring 75 Duro 6-3/4"ID X 7-1/4"OD X 1/4"CS

6-3/4"ID X 7-1/4"OD X 1/4"CS Viton® O-Ring 75 Duro Material: Fluoro-Elastomer, most commonly referred to as Viton® or FKM, is the second most commonly used O-Ring elastomer compound as it offers outstanding heat stability and excellent resistance to acids, fuels (gasoline, fuels with methanol content), liquefied petroleum gas (LPG), aliphatic hydrocarbons (butane, natural gas, propane), diesel oil, non-flammable hydraulic fluids (HFD), mineral and vegetable oils and greases, silicone oil and grease, aliphatic, aromatic hydrocarbons (benzene, toluene), chlorinated hydrocarbons (trichlorethylene and carbon tetrachloride), chlorine water, and many organic solvents and chemicals.  In addition, Fluoro-Elastomers have very good resistance to aging, weather and ozone.  The standard durometer (hardness) is 75 duro and they are typically black or brown in color. The operating temperature range is generally -20° to 400°F. Viton® is not recommended for polar solvents, low molecular weight organic
