Product Introduction
Description
Piston Seals AQ is a double-acting piston seal utilizing high-performance PTFE paired with an elastomer energizer and x-ring for optimum performance and durability. Used for sealing between two media such as fluid and gas.
PTFE seal ring and x-ring together provides the dynamic sealing function, while the elastomeric energizer provides the static sealing. AQ seals face includes pressure notches, which makes the seal very responsive to changes in pressure or direction of travel.
It is especially effective in applications where two different types of media need to be separated, such as in piston accumulators, intensifiers, and position-holding applications. This makes this seal a good choice for applications such as stabilizers, accumulators, manlifts, and industrial presses.
