Encapsulated, or Teflex, O-rings are made from more than one type of material. The inside is made of rubber (often VMQ or FKM) and the outside is FEP or PFA. As a result, the flexible core is protected by a jacket that is highly chemically resistant.

It is important to ensure that the material used for your O-ring is suitable for the conditions under which it will be used. So you should always consider the medium, the temperature, the pressure and the uptime. The summary below provides concise information about the most popular materials and their properties.

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance.

When is passivation ofstainless steelrequired

ERIKS offers a very extensive range of O-rings and O-ring sets. Do you know exactly which dimensions and which material are suitable for your application? Then you can easily choose an O-ring with our O-ring selector.

Our easy-to-use O-ring calculator lets you calculate the dimensions for your O-ring. These dimensions depend on the groove where the O-ring will seat (and other factors).

You determine which material is suitable for your O-ring based on the medium, temperature and pressure in your application. This article explains what steps you need to take. You should also use our Chemical Resistance Guide to find out which rubber compound is suitable for the medium in your application.

Most O-rings are made of NBR, or nitrile. This rubber material is ideal for sealing hydraulic oils or lubricating oils. NBR on the other hand is not very resistant to UV radiation, ageing and high temperatures (above +120°C).

Passivation is the process of treating or coating a metal in order to reduce the chemical reactivity of its surface. In stainless steel, passivation means removing the free iron from the surface of the metal using an acid solution to prevent rust. When the surface iron is removed, the other components of the alloy (primarily chromium, often nickel as well) are left behind as a surface layer over the underlying steel. Upon exposure to air, these elements react with oxygen to form an oxide layer that protects the rest of the steel from corrosion. This corrosion-resistant surface can be damaged through mechanical means or heat or chemical damage. When that happens, iron is exposed and the item is once again subject to rusting. For this reason, passivation may need to be performed on a regular basis. In both home and commercial settings exposure to things like cleaning solutions, bleach or salt (oceanic environments) all will contribute to the need for regular passivation of the stainless steel.

Our O-rings are either offered in metric sizes or according to international standards. The international standards are AS568, BS1806, ISO3601, French R, DIN3771, BS4518, JIS and DIN11864.

The price of our seals is shown on the product pages. If the price is not immediately visible, it will be displayed after you have logged in.

O-rings are sealing products that are mainly suitable for static applications, but they can sometimes be used in dynamic applications. However, movement can cause O-rings to twist. In these cases, we recommend using an X-ring, a double lip oil seal or a hydraulic/pneumatic seal.

How to passivate stainless steelwith citric acid

Passivation chemicals forstainless steel

You use FFKM O-rings for the very highest temperatures and the strongest acids, for example Kalrez O-rings. With a maximum temperature of +327°C, this material offers unbeatable performance. Like FKM seals, only special compounds of these rubber O-rings perform well in cold conditions.

PTFE, also known by the brand name Teflon, is highly resistant to strong acids and bases. This material is not wear-resistant, and unlike the elastomers mentioned above, also not elastic. So PTFE O-rings are only suitable for static applications.

Historically nitric acid has been used to passivate stainless steel, but recently a safer and more effective means using citric acid has been introduced. Unlike nitric acid, citric acid passivation (the active ingredient in Citrisurf®) has many advantages:

For applications that involve extremely high temperatures, an FKM O-ring, commonly referred to by the brand name as a Viton O-ring, is a good solution. This material is capable of withstanding temperatures up to +200°C. Furthermore, the standard compounds are resistant to many strong acids and bases, but not to hot water or steam. Only a few special FKM compounds are suitable for applications that involve unusually low temperatures (-40°C or lower).

The size of an O-ring depends on the groove in which it seats. Use the O-ring calculator to determine the right dimensions for your seal. Next, choose a suitable O-ring using the O-ring selector.

EPDM is also often used as a material for O-rings. This material is well adapted to various solvents, hot water and steam. All EPDM O-rings can withstand low temperatures (down to -50°C) and are resistant to UV radiation and ageing. Some compounds are also suitable for high temperatures (up to +150°C).
