Z8 (Piston Seals)

The pneumatic cylinder seal profile Z8 is a lip seal for pistons in pneumatic cylinders and for valves. It requires small housing dimensions and is interchangeable with profile Z4. The special design of the lip seal profile Z8 offers the following advantages when used in pneumatic equipment.

• Good sealing performance in small installation grooves.

• Smooth running due to optimum sealing lip geometry retaining the lubrication film but also due to choice of compound which is our SFR elastomer compound well proven in pneumatics.

• Low static and dynamic friction due to smallest possible sections.

• For use in dry air and air free from oil. Initial lubrication on assembly is essential for a long service life.

• Function guaranteed by lip seal design.

• Easily assembled into seal grooves.

• Also suited for cylinders with cushioning.
