The Hallite GPS is a double-acting piston seal utilizing Hallite’s high-performance Armorlene® HLX PTFE paired with an elastomer energizer and x-ring for optimum performance and durability. The Armorlene® PTFE seal ring and the x-ring together provides the dynamic sealing function, while the elastomeric energizer provides the static sealing. The standard GPS seal face includes pressure notches, which makes the seal very responsive to changes in pressure or direction of travel.
Hallite GPS seals are 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. Designed for basic grooves, the GPS seal fits the same ISO 7425-1 housing as the Hallite P16 and P54 series.
