    Hollow Tapered Plugs

    Image of Product. Front orientation. Contains Annotated. Protective Plugs. Hollow Tapered Plugs.
    A hollow construction makes these plugs extra flexible, so they compress for easy installation and a snug fit. The tapered profile fits a range of hole diameters. If you flip the plug over, it can be used as a cap.
    Polyethylene—Convenient and economical. Instead of cleaning and reusing, just toss and grab a new plug.

    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.

    Metal Round Caps

    Image of Product. Front orientation. Protective Caps. Metal Round Caps.
    Tougher than plastic and rubber caps for best protection from impact and wear. These caps cover pipe ends to prevent damage and keep out dust and debris during shipping and storage.
    Steel—The strongest caps, but moisture can cause them to rust.
    Aluminum—Use aluminum caps instead of steel to prevent corrosion from spreading to aluminum pipe and tubing.
    18-8 Stainless Steel—Our most corrosion-resistant caps for parts exposed to moisture and the outdoors.
