    Round Caps

    Cover pipe and rods to keep dust and coatings out of threads. These caps also prevent dents and nicks during shipping and storage. Push them onto just about any round object.
    Plastic
    Vinyl Plastic—A good all-around choice, these durable caps won’t rip or shred, even with repeated use. They also hold up to oils, mild acids, and solvents. Caps are flexible and conform to parts for a tight fit.
    High-Temperature Vinyl Plastic Blend—Good for most paint baking and electrocoating processes, these caps are a lower-cost alternative to silicone rubber. They're flexible to conform for a tight fit.
    Polyethylene—These tough caps are hard and wear resistant to hold up against scrapes and gouges.

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

    Grab and tug the tab with your fingertips for easier removal than other caps. These cover threads and openings to keep out dust, paint, and coatings or prevent damage.

    TPE Rubber—Extremely stretchable for use over and over without losing shape.
    Style B—The tab is textured for a good grasp, even with wet or gloved hands.
    Style C—Bright yellow to stand out when installed or if dropped on the floor. The tab is ribbed for a secure grip.

    Screw-On Caps

    Thread onto male pipe and fittings for the most secure fit. These caps keep dust, paint, and coatings out of threads and pipe. They also protect from damage during manufacturing, shipping, and storage.
    Polyethylene—These tough caps are hard and wear resistant to hold up against scrapes and gouges.
    Aluminum—Use aluminum caps instead of steel to prevent corrosion from spreading to aluminum pipe and tubing.

    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.
