The 206 Series Symmetrical Piston U-cup is a popular System Seals design used in standard duty applications. Its symmetrical design creates equal seal force across both seal lips. This gives the seal the capability to function as both a piston seal and rod seal or alternatively to seal dynamically on both the outside and inside diameters. This feature is often appreciated when reduced product inventories are desired. Manufactured in a variety of materials and sizes from 6 mm 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 206 Series Symmetrical Piston U-cup seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter, MP50 and MN01 injection-molded TPU. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
