The SNI 24 u-ring is a single-acting rod seal with an asymmetrical cross section design. Due to the indented inner seal lip, the prestress is led inwards to strengthen the sealing function even with low pressures.
U-rings can be installed in both solid and split housings. Please note for a solid housing application a minimum width is necessary and suitable installation tools may be required.
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.
