PE piston seal set is a double-acting seal consisting of a PTFE seal ring, a QUAD-Ring and an O-Ring as preload element. Four radial notches on both sides of the PTFE seal ring ensure direct pressurized effect on the seal set through media under any working condition. The combination of a QUAD-Ring and the PTFE seal ring provides not only excellent sealing performance but any application requiring media separation such as accumulator and positioning cylinder. Other applications include machine tools, presses, and heavy-duty suspension cylinders.
