The lip rings B1R and B2R are primarily used for pneumatic applications, however they are often used with low pressure hydraulic, because of their geometry and flexibility. The outside diameter is provided with oversize, so the outer lip serves as a tight fit. This profile can be snapped inside closed grooves. The profile B2R has a stronger dynamic lip inside, than the profile B1R.
MAIN ADVANTAGES ARE
- usable for several applications, pneumatic and hydraulic
- in different compounds available, NBR, FKM, EPDM
- very easy to install

For a perfect function it is necessary to design the groove width slightly bigger, compared to the ring width. Please notice here the data on the scale: dimension H to dimension L.
For friction reduction and herewith contact pressure of the dynamic sealing lip, the groove ground diameter can be made with oversize (H11). Don?t pull the lip seal over sharp edges.
All details are based on decades of experience with sealing technology. Although, with practicle operation, through unknown parameters, there can not be given any guarantee for these general statements.
The standard material is an approved elastomer compound on NBR-basic with a hardness of about 84 Shore A. Special compounds on FKM-basic (Viton), for operation temperature up to 200°C is possible.
In case of special operation conditions, which range outside specified operation parameters, please get in contact with our application technology department.
