Materials
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

Chemical compatibility
A "Chemical compatibility guide" catalogue can be downloaded from the Literature section. You can also use our online "Chemical compatibility" tool free of charge.
These two tools enable you to measure the behaviour of our materials that come into contact with the majority of existing fluids. The data displayed is the result of rigorous testing at the ambient temperature and takes previous publications into consideration. Test results are not fully representative because of the specific features of your application. The tests performed actually do not consider additives and impurities that may exist under actual conditions of use, nor the potential elevation of temperatures. Other parameters can also alter the behaviour of our materials, such as the hardness, persistence, abrasion, etc. We therefore recommend performing your own tests to verify the compatibility of our materials depending on your specific application. Our technical team can provide you with any additional information.
Design recommendations
The tolerances on the inside diameters Ød1 set out in the table below relate to standard ISO 3601-1:2008. If the dimensions of an O'Ring are not specified in standard ISO 3601-1:2008, we recommend that you calculate the tolerances to apply to the inside diameter Ød1 as follows:
Tolerance on Ød1 = ± [(d10′95 x 0,009) + 0,11]

The O'Ring ensures sealing under radial deformation at the cross-section Ød2.
For rod sealing (inside sealing), the dimension of the O'Ring should be selected so that the outside diameter of the O'Ring is 0.5% to 5% greater than the groove diameter Ød6.
For piston sealing (outside sealing), the dimension of the O'Ring should be selected so that the inside diameter Ød1 of the O'Ring is 0.5% to 8% smaller than the groove diameter Ød3.

These values are provided for information purposes only. We recommend refining your design using our O'Ring calculator, which is available free in the "Tools" tab on the website.
Flange and cover sealing is generally ensured by an O'Ring that is subject to axial deformation. The groove dimensions are determined according to the direction of the pressure.
When the pressure is directed from the outside in, the inside diameter Ød1 of the O'Ring must be 0% to 2% less than the inside diameter of the groove.
On the other hand, when the pressure is directed from the inside out, the outside diameter of the O'Ring must be 0% to 2% greater than the outside diameter of the groove.
These recommendations depend on the dimensions of the O-ring concerned.

We use these types of fittings for cover or flange seals. This type of groove is difficult to machine and only allows a reduced swelling of the O'Ring. The values included in the table below set out all of our recommendations so that the connection between the cross-section Ød2 of the O'Ring and the length of the edge C gives a full seal. It is, however, preferable to use a rectangular groove as far as possible.
The table below sets out the design recommendations - Triangular groove - Static sealing.

In specific cases, the O'Ring must be mechanically held in its groove. In this case, it is possible to mount the O'Ring in a trapezoidal groove. This installation is typically used in several static applications, and only from a cross-section of 3.53 mm. The installation dimensions are listed in the table below.

O'Rings can be used as sealing components for hydraulic applications in linear motion. However, they have an average efficiency and are only suitable for relatively low travel and frequencies. Other seal profiles are prioritised for such applications (see the hydraulic seals range).
For rod sealing (inside sealing), the dimension of the O'Ring should be selected so that the outside diameter of the O'Ring is 0.5% to 5% greater than the groove diameter Ød6.
For piston sealing (outside sealing), the dimension of the O'Ring should be selected so that the inside diameter Ød1 of the O'Ring is 0.5% to 5% smaller than the groove diameter Ød3.

O'Rings can be used for rotational movements in certain less aggressive and casual applications. However, other seal profiles are prioritised for such applications (see the rotary seals range). In general, O'Rings have a tendency to contract under the effects of heat, which increases tightening on the rotating shaft, preventing the formation of a lubricating film and increasing friction at the same time. In order to prevent this type of significant wear, we recommend selecting an O'Ring dimension where the outside diameter of the O'Ring is 0.5% to 5% larger than the groove diameter Ød6 in the shaft seal. Conversely, the inside diameter Ød1 of the O'Ring must be 0.5% to 5% smaller than the groove diameter Ød3.
Rubber-based materials with MOS₂ or PTFE reduce friction and increase the lifespan of O'Rings. The table below sets out the installation dimensions to follow.

The float-mounting principle, without radial deformation on the O'Ring, is mainly used for pneumatic applications. When pressurised, a volume of air leaks out until the gap is filled between the piston and the cylinder (piston seal) or between the rod and the tip of the cylinder (rod seal).
For rod sealing (inside sealing), the dimension of the O'Ring should be selected so that the inside diameter Ød1 of the O'Ring is 0.5% to 5% smaller than the rod diameter Ød5.
For piston sealing (outside sealing), the dimension of the O'Ring should be selected so that the outside diameter of the O'Ring is 0.5% to 5% larger than the groove diameter Ød3.

With often problematic lubrication conditions, correct O'Ring operation in linear motion can be achieved with a very reduced radial deformation.
For rod sealing (inside sealing), the dimension of the O'Ring should be selected so that the outside diameter of the O'Ring is 0.5% to 5% greater than the groove diameter Ød6.
For piston sealing (outside sealing), the dimension of the O'Ring should be selected so that the inside diameter Ød1 of the O'Ring is 0.5% to 5% smaller than the groove diameter Ød3.

These values are provided for information purposes only. We recommend refining your design using our O'Ring calculator, which is available free in the "Tools" tab on the website.
Against the extrusion of O'Rings under significant pressures, it's best to use back-up rings, BECA 008, BECA 008 P, BECA 011 and BECA 012, and O'Rings with a hardness of 70 Shore A, in line with the following parameters:
- - Pressures above 5.0 MPa for diameters Ød1 > 50,00 mm
- - Pressures above 10.0 MPa for diameters Ød1 ≤ 50,00 mm
However, this is not always possible if there is a lack of space in the housing. In this case, the tolerances of the mechanical parts must be adapted depending on the cross-section and the O'Ring hardness. It is important to scrupulously observe the extrusion gaps to prevent any O'Ring creep, which would lead to its complete destruction.

To make the tubes and rods, we recommend using non-porous steel or cast iron. For dynamic applications, brass and untreated stainless steel, as well as aluminium, are not as hard and are therefore not recommended, as they would be subjected to a lot of wear.
The roughness means that the sealing must be of a high quality. The surface roughness of grooves improves during alternating pressures.

Assembly recommendations
Several essential rules must be followed before fitting the O'Rings:
- Check that the mechanical parts (rod and bore parts) have a chamfer length that is in line with our recommendations,
- Remove the flash and chamfer or round off the sharp edges and holes; cover the threaded parts,
- Remove the machining shavings and all impurities and other foreign bodies. Thoroughly clean all of the mechanical parts,
- Grease or oil the O'Ring and mechanical parts to make it easier to fit. For this purpose, ensure upstream that the lubricants are compatible with the O'Ring materials. Avoid greases containing solid additives (molybdenum disulfide or zinc sulfide),
- If using installation tools, check that they are clean and do not have sharp edges.
