PF piston seal set is a double-acting seal consisting of a PTFE seal ring, a QUAD-Ring and two O-Rings as preload element. Special seal lips on the PTFE ring energized by two O-Rings ensure optimum pressure distribution in operation and help to enhance gas sealing performance. 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.
