18 different sizes come in a lightweight and convenient storage kit to accommodate a variety of tasks. This is a compatibility table and compound from list to view comparability rating of the o ring.
What S The Difference Between Buna Vs Viton O Rings
Nitrile o rings gasoline. Effective from 40c to 120c. Vitons range is to 40 f to 450 f. Buna o rings are used in applications for engines gearboxes aircraft pumps and water. Chemical processing industry o rings cpi o rings oil and gas drilling o rings ed resistant o rings norsok m 710 seals nace tm0297 seals automotive o rings and oil seals. The nitrile o rings are resistant to heat highlow temperature air water petroleum products mineral oil and hydraulic fluids natural gases kerosene silicon fluids non aromatic fuels and solvents. Constructed of viton polymer these o rings provide excellent protection during high heat applications 400 and are resistant to aggressive fuels and chemicals.
Nitriles temperature ranges as low as 70 f and up to 275 f. 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. Buna o rings also known as nitrile or nbr o rings offer excellent sealing and mechanical properties at a low cost. Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure. I found data that stated 75 duro viton only ranges down to 15 f which is far from gasolines flashpoint of 45f. This material has a desirable set of properties including low compression set high resistance to abrasion and good tensile strength.
The flash point of ethanol or ethyl alcohol is 55 f and gasoline or petrol is 45 f. Buna o rings have resistance to common lubricants and are recommended for crude oil gasoline propane petroleum oils and water. O ring chemical compatibility chart learn how different o ring materials and chemicals interact. Buna n rings with durometer 70 shore a can offer hood physical properties and provide excellent resistance to petroleum products. Good wear resistance moderate compression set resistance moderate short term resilience excellent permeation resistance. O ring compatibility chart javascript seems to be disabled in your browser.
Get durable buna n and viton o rings from grainger to help tightly seal connections in a wide range of industrial applications. Slightly harder durometer 75 shore a fluorocarbon viton rings can offer low swell and resist a diverse range of chemicals uv light and ozone. Nitrile o rings also called nbr or buna n nitrile o rings are probably the most economical and widely used elastomer out there.
