What are rubber o-rings used for?
What are o rings used for? O rings are used to block a path which may otherwise allow a liquid or a gas to escape. The o ring is placed into a groove to secure them in place, and then compressed between two surfaces.
What kind of rubber are o-rings?
Nitrile
Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.
Are silicone o-rings better than rubber?
In conclusion, silicone ‘O’ rings can be applied to high-temperature applications or where damage from the elements may otherwise be an issue. In such cases, there are several other rubber ‘O’ ring materials that offer a more well-rounded package of benefits, including thermal stability and chemical resistance.
What is the difference between an O-ring and a gasket?
Gaskets are flat pieces of material used to make a seal between two flat surfaces, usually with a bolted joint. O-rings are round, ring-shaped pieces that must set in a groove to create a seal between two parts.
Are there different types of O-rings?
Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton). Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.
How long does an O-ring last?

What O-ring material is best for high pressure?
O-Ring Durometer High-durometer o-rings are better suited for higher pressures and are more resistant to extrusion. Hard material yields higher pressure required to force the o-ring into extruding. The only drawback to a high durometer is the decreased squeeze of the o-ring.

How do you make an o-ring seal better?
How do I choose an o-ring?
The size of an O-ring can be determined by measuring the diameters and the width of the cross-section. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).
What can I use instead of an O-ring?
Alternatives to O-rings for static sealing
- Extruded and cut seal profiles. One alternative to O-rings are extruded and cut seal profiles.
- Rubber substitutes. O-rings are often made of rubber elastomers.
- Flange seals.
- Static radial seal.
- Axial face seals.
- Press-in-place seals.
- Composite sealing plates.
- Parker Hannifin.
Are all rubber o-rings the same?
Whether sold individually, in large wholesale batches or – as is increasingly common – as part of a highly flexible range of o-ring kits, the basic form and role of o-rings are generally the same across the board.
