    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

    Loop 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.
    Loop End—The most secure attachment method. With fully closed loops, there's no risk of slipping off.
    Corrosion-Resistant 302 Stainless Steel—Won’t corrode from exposure to moisture and mild chemicals, including ammonia often found in cleaning solutions. These springs are easier to extend than steel, but can’t handle as high a load.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
