272 Buna/NBR Nitrile O-Ring 90A Shore Black, -25 Pack

276 Viton / FKM O-ring 90A Shore Brown, -25 Pack.

It is compatible for use with water and steam, silicone oil and grease, polar solvents (alcohols), acids, glycol-based brake fluids, ozone, and weathering. It is vulnerable to many oils, gasoline, and solvents.

Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.and is compatible for use with petroleum, HFA, HFB and HFC fluids, vegetable oil, alcohol, acids and aliphatic hydrocarbons.

. Fluorosilicone has very good resistance to ozone, weathering, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, high molecular weight chlorinated aromatic hydrocarbons, and has better mineral oil, fuel, and aromatic hydrocarbons (benzene) compatibility than Fluorosilicone.Fluorosilicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121degrees C), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels.
