The 137 Series U-cup seal is a highperformance, double-lipped seal for use as in high-clearance applications, typically in moderate to high-pressure environments. Its asymmetrical design ensures that the seal lip forces are optimized for every cross section and diameter. The full-face 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 up to 2100 mm in standard or custom diameters.
