The 117 Series U-cup seal is a high-performance, double-lipped seal for use as a primary seal, typically in moderate to high-pressure applications. Its asymmetrical design ensures that the seal lip forces are optimized for every cross section and diameter. When used within a sealing system, the 117 plays a key component of System Seals’ Zero Leak Technology. Manufactured in a variety of materials and sizes from 6 mm up to 2100 mm in standard or custom diameters.
High pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
Highly extrusion resistant
Available in diameters up to 2100 mm
The 117 Series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter, and MP50 injection-molded TPU. To suit a variety of applications the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
