    With a metal core or base plate for added strength, these bumpers withstand repeated impacts for a longer service life than all-rubber bumpers. You can also use them as spacers, vibration dampers, and noise reducers. Twist them onto a threaded stud on your equipment, or pair them with your own stud to create a custom-length bumper.

    Multipurpose Neoprene—A good choice for oily equipment that's exposed to sunlight, rain, and ozone. These aren't as oil resistant as Buna-N bumpers, but they can be used outdoors.
    Abrasion-Resistant Polyurethane Rubber—Our toughest rubber bumpers, they keep their shape even when knocked and scraped by metal and other abrasive materials. They're often used on industrial vehicles, conveyors, and heavy construction equipment.
    Oil-Resistant Buna-N—These bumpers resist oil and fuels better than other rubber bumpers. Use them on frequently lubricated machinery and oily equipment, such as engines and pumps.
    Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
