Nitriles temperature ranges as low as 70 f and up to 275 f. Slightly harder durometer 75 shore a fluorocarbon viton rings can offer low swell and resist a diverse range of chemicals uv light and ozone.
Your Connection Is Only As Good As Its O Ring Hydraulics
Nitrile o rings gasoline. Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure. O ring compatibility chart javascript seems to be disabled in your browser. The flash point of ethanol or ethyl alcohol is 55 f and gasoline or petrol is 45 f. Buna o rings are used in applications for engines gearboxes aircraft pumps and water. Buna n rings with durometer 70 shore a can offer hood physical properties and provide excellent resistance to petroleum products. Buna o rings also known as nitrile or nbr o rings offer excellent sealing and mechanical properties at a low cost.
O ring chemical compatibility chart learn how different o ring materials and chemicals interact. Vitons range is to 40 f to 450 f. 18 different sizes come in a lightweight and convenient storage kit to accommodate a variety of tasks. Good wear resistance moderate compression set resistance moderate short term resilience excellent permeation resistance. Get durable buna n and viton o rings from grainger to help tightly seal connections in a wide range of industrial applications. Great for plumbing hydraulics air gas connections and man industrial applications this set of o rings comes neatly organized in a pvc storage case for easy portability to any job.
Constructed of viton polymer these o rings provide excellent protection during high heat applications 400 and are resistant to aggressive fuels and chemicals. Nitrile o rings also called nbr or buna n nitrile o rings are probably the most economical and widely used elastomer out there. I found data that stated 75 duro viton only ranges down to 15 f which is far from gasolines flashpoint of 45f. This is a compatibility table and compound from list to view comparability rating of the o ring. This material has a desirable set of properties including low compression set high resistance to abrasion and good tensile strength. Buna o rings have resistance to common lubricants and are recommended for crude oil gasoline propane petroleum oils and water.
