    Long-Life Rubber Compression Springs

    Image of Product. Front orientation. Compression Springs. Long-Life Rubber Compression Springs.
    When longevity matters most, these springs deliver. Made from a polyester/rubber blend, they stay springy longer than metal and plastic springs—with documented cases up to one million cycles.
    Flanges on the ends create a flat mounting surface.
    Hardness—As the durometer gets higher, the springs absorb more energy but compress less.

    Extension Springs

    Elongated-Hook End

    The farther you stretch these springs, the harder they pull to bring the two ends back together. They're commonly used to tension cable, return an air cylinder to its starting point, or hold a door closed.
    Elongated-Hook End—With deeper hooks than standard hook end springs, these are less likely to slip off. However, they’re more prone to breaking if overstretched.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
