The profile Z7 pneumatic piston seal is a U-ring with an integral guiding surface for single-acting pistons. Its design offers the following advantages:

■ No metallic contact between piston and cylinder which prevents scoring, especially in the case of light metal and plastic cylinders.
■ Smooth running thanks to optimized sealing lip geometry retaining the lubrication film, and the proper choice of elastomer compounds.
■ For use in dry and oil-free air. Initial lubrication on assembly is essential for long service life.
■ Easy assembly on one-piece piston.
