    Profile

    Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    Profile

    Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals. They have two high-strength backup rings that protect against extrusion.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
