Buna Seals Vs Viton Seals Which Is Worth It Rg Group
Viton o rings vs buna. Viton fluorocarbon type a. O rings made of viton are perfect for scuba diving automobile engines and valves of all kinds. It resists corrosion from a greater variety of fluids and chemicals than any non fluorinated elastomer. Buna on the other hand is only effective up to 250f. Meanwhile buna is only effective in the same manner up to 250f and is the better option for low temperature seals as low as 30f. As two of the most commonly used elastomers both viton and nitrile o rings have some fantastic properties.
Viton vs nitrile o rings. Unlike epdm viton is compatible with oils fuels lubricants and most mineral acids. Which seal for your application. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in. For example viton over buna is essential for high temperature applications which provides an indefinite seal up to 400f and about a 2 day seal for temperatures up to 600f. Both offer excellent compression set and have a wide range of uses in industrial and domestic applications.
Viton has a temperature resistance up to about 300 c. Semicon o rings sem o rings ultra high purity seals low outgassing seals low particulate o rings. Vinylidene fluoride hexafluoropropylene and tetrafluoroethylene are used to manufacture viton. Viton seals hold indefinitely at temperatures up to 400f and can last up to 48 hours at temperatures up to 600f. Viton is the choice over buna for high temperature applications. Viton seals provide an indefinite seal for temperatures up to 400f and for temperatures up to 600f they offer an excellent seal for more than 48 hours.
