    Tapered Plugs

    Don't worry about having the exact size you need on hand—these plugs are shaped to fit a range of diameters. Push in until they're snug to mask holes during coating and finishing.
    SBR Rubber—A good multipurpose option. Flexible and durable, these plugs can be used over and over without cracking or breaking down.
    Chemical-Resistant EPDM—These plugs won't swell or crack when masking parts during plating, anodizing, and other chemical finishing.
    High-Temperature Silicone Rubber—Withstand multiple passes when paint baking, powder coating, and electroplating.
    Cork—The original plug material, cork is compressible and flexible for a tight fit. These plugs are also slightly porous to allow some gas exchange. They are a sustainable and biodegradable alternative to rubber.
    1 Hole and 2 Holes—Feed tubing through holes to connect bottles to other lab equipment, or insert an instrument such as a thermometer. The holes also allow pressure to escape.

    Style 2

    Press firmly into place for a tighter hold than push-in plugs. These are good for semi-permanent installations, such as finishing the ends of posts and furniture. To remove, you’ll need a tool such as a flat-head screwdriver to pop them out.
    Style 1—Flexible ribs compress and expand to secure the plug.
    Style 2—Often used to keep dirt and moisture out of poles, these plugs have straps that flex and then hold them in place.
    Polyethylene—A balance of wear and chemical resistance for use in a variety of environments. These plugs withstand scratches and scrapes as well as mild acids, solvents, and chemical cleaners.
    High-Strength Glass-Filled Plastic—Tough for the most demanding environments, including outdoor installations.
