PRODUCT ADVANTAGES

U-rings made of NBR are primarily used with low pressures as the seal lips are provided with radial pre-stress which is strengthened by the pressure of the system. Apart from applications in hydraulics, this NBR design can also be used in pneumatic applications. For special applications, different materials are also available.
