An X-ring, also referred to as a Quad ring is what is known as a four-lip seal. In other words, they have at least four sealing surfaces when installed. X-rings are designed to replace an O-ring in those instances where the latter has been performing less well. One example of this might be a dynamic application. The scope for X-rings is very large, not only from the point of view of design, but also due to availability in various elastomers. X-rings are available in the same sizes as the O-rings in the American size according to standard AS 568A. Other sizes are also available on request.


The benefits of an X-ring are that you need less force to press in the X-ring. This allows friction and therefore wear to be reduced with dynamic seals. The four sealing lips increase the sealing capacity and also form a lubricating groove that is extremely favourable for dynamic seals. The main advantage is that an X-ring has high stability in a dynamic application (particularly in the case of sliding seals). The service life and reliability of your seal are thus significantly improved.


Standard X-rings are available in the compounds NBR, FKM and EPDM. In order to help you with choosing a rubber compound we have produced an overview of suitable compounds on the basis of different industries. On the basis of the industry that applies to you, you can choose the appropriate compound.
