    Tapered Caps

    Image of Product. Front orientation. Protective Caps. Tapered Caps.
    Don't worry about having the exact size you need on hand. These caps are shaped to fit a range of ODs—just keep pushing on until they're snug. Because they make less contact with the parts they cover, they’re easier to remove than straight caps. In a pinch, you can flip tapered caps over and use them as plugs.
    Polyethylene—Convenient and economical, these flexible caps are one and done. Instead of cleaning and reusing, just toss and grab a new cap.

    Polyethylene—These tough caps are hard and wear resistant to hold up against scrapes and gouges.

    Polyethylene—Convenient and economical. Instead of cleaning and reusing, just toss and grab a new plug.
