Series AP02: Piston U-Cup Seal with Active Backup Ring
The AP02 Series is a rubber or polyurethane piston seal with a U-cup design and active backup ring. This pressure-relieving design is ideal for back-to-back tandem arrangements. The active backup ring allows larger clearances and higher pressures. The asymmetrical design of the U-cup seal allows maximum stability in the seal groove. It is an ideal choice when pressure trapping is a problem.
The AR06 Series U-Cup, due to its versatility as both a piston and rod seal, can be used in a wide variety of applications. Recommended where dynamic sealing action is required simultaneously on the inside and outside diameters. Examples are often encountered in specialty sensors, bolt tension equipment and hollow cylinders.
Typical applications include:
Hydraulic Cylinder Rebuild
Injection Molding Machines
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 2000mm
