    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.

    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.
    High-Temperature Silicone Rubber—Withstand multiple passes when paint baking, powder coating, and electroplating. Caps are flexible to conform to parts.
