The 139 Series U-Cup seal is a high-performance, U-Cup seal for use in high-clearance applications, typically in moderate to highpressure environments. Its asymmetrical design ensures that the seal lip forces are optimized for every cross section and diameter. The integrated backup ring supports the seal and ensures maximum extrusion resistance in a larger than normal clearance application. Manufactured in a variety of materials and sizes from 6 mm to 2100 mm in diameter in standard or custom sizes.
