    Stacking Configurations

    The strongest disc springs we offer for maintaining tension and separating components on shafts, under bolt heads, and at the end of valves. Unlike spring lock washers, they return to their original height again and again when decompressed. Also known as Belleville disc springs.
    To increase working load or deflection, stack multiple springs. A nested stack increases working load; an inverted stack increases deflection. In a nested and inverted stack, both load and deflection increase. Multiply the original working load or deflection (depending on your configuration) by the number of springs to find your new total.
    Highly Corrosion-Resistant Extreme-Temperature Nickel—Even after long-term exposure to extreme temperatures, from -400° to 1100° F, these 718 nickel springs stay strong and corrosion resistant. They won't break down from harsh chemicals or salt water. 718 nickel is also known as Inconel.

    Cartridge Mechanical Shaft Seals

    Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled. All have a carbon washer that is self-lubricating. However, this means their washer is too soft to be used with abrasive liquids and liquids with harsh additives.
    Fluoroelastomer Diaphragm—Seals with a fluoroelastomer diaphragm can be used with a wider range of chemicals than EPDM diaphragms, including benzene, butyl alcohol, and fuels.
    EPDM Diaphragm—Seals with an EPDM diaphragm won’t break down from exposure to water and steam. However, they are for use with fewer chemicals.

    Extreme-Strength 718 Nickel—Twice as strong as 400 nickel washers, these washers are comparable to our strongest steel washers. Expose them to extreme temperatures—1300° F down to -400° F—and corrosive elements, such as salt water, sulfuric acid, and other acids. Also known as Inconel 718.
