What are Viton O-rings made out of?
synthetic rubber
Viton® O-Rings Viton is a brand of synthetic rubber and fluoropolymer elastomer commonly used in O-rings and other molded extruded goods.
How are Viton O-rings measured?
How to Measure O-Rings
- Place the O-ring on a clean, flat, level surface.
- Determine the inside diameter by using a ruler to measure from one inner edge to another.
- Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner.
- Finally, measure the cross-section.
What is the temperature range of Viton O-rings?
Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours.
Are Viton O-rings good?
Properties of Viton O-rings It offers the best fluid resistance of any commercial rubber. At high temperatures, Viton retains good mechanical properties compared to other elastomers. It remains substantially elastic and is resistant to oils and chemicals at elevated temperatures.
How do you select O-ring cross section?
Groove Design: O-Ring Seals
- Cross-section. Select an O-Ring cross-section size from the available standard sizes.
- Clearance.
- Check the Clearance.
- Calculate the O-Ring groove dimensions.
- Groove Width.
- Percent Gland Fill.
- Calculate the Seal Squeeze.
- Select the Seal.
How do you inspect o-rings?
The setup time to inspect o-rings is extremely small. The user must simply enter the nominal diameter and cross section values and click OK. In 0.1 seconds the system will measure hundreds or even thousands of o-rings at a time, at 12 microns.
What temp do O rings melt?
O-Ring Material Temperature Guide
| Degrees in Fahrenheit (F◦) | Degrees in Celsius (C◦) | Polymer Type |
|---|---|---|
| – 30° to 250° | – 34° to 121° | Nitrile (General Service) |
| – 65° to 225° | – 55° to 107° | Nitrile (Low Temperature) |
| – 15° to 500° | – 26° to 260° | Perfluoroelastomer (Parofluor) |
| – 5° to 350° | – 21° to 177° | Polyacrylate |
What is the difference between Buna and Viton O rings?
Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F. Buna is effective to 250°F. Viton offers universal chemical resistance for sealing applications for oils, fuels, and mineral acids.
What’s the chemical resistance of Viton O rings?
O-ring compatibility chart offers guidance on chemical resistance and swell for Viton o-rings, FFKM o-rings, Silicone o-rings, Teflon o-rings and more. O-ring compatibility plays a critical role in o-ring performance – find the right material for your application and avoid o-ring failures. Contact Login Cart Buy O-Rings Buy X-Rings
Why are Viton O rings used in gaskets?
Viton® O-rings (FKM o-rings) have low gas permeability and Viton o-rings (FKM o-rings) are commonly used as gaskets in fuel system sealing applications. Other fluorocarbon compounds can also offer improved resistance to acids, fuels, water and steam.
How long does it take to make Viton O rings?
When not in stock most custom Viton ® O-Rings can be made in a few weeks without tooling fees. FKM and Viton ® material types for high temperature seals and chemical resistant gaskets include the following specific types: A, B, F, GLT, GFLT, XLT, ULT, ETP, TBR.
What should the temp of a Viton ring be?
GFLT Viton o-rings are excellent ‘good for low temperature’ orings. Sometimes low temperature resistance is not preferred in static applications for traditional Viton® o-rings , and is limited to approximately -15°F (-26°C). When used in dynamic applications, the low temperature is between 5°F and 0°F (-15°C and -18°C).
