HERCULES PSQ PISTON SAEL

    PSQ Piston Seal

    These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible.
    NOTE: Piston diameter “I” dimensions are given for pistons without wear rings.
