The 227 Series is a heavy duty 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.
