The DR range of seals have a slightly longer working length than the PRR, but are smaller in external diameter. These seals are manufactured in a limited range of materials and sizes from 10 to 25 mm. shaft diameter, generally in high volumes for the domestic and marine markets.They are particularly suited to applications where space is limited and are normally used with stationary seats of types L and IN.
