Caps and Plugs USA manufactures straight wall plastic caps and plugs in Southern California. Buy American-made products at factory-direct prices, with multiple sizes and samples available to help you find the right fit.
Our flangeless caps and plugs offer a compact profile without an extended rim. Their streamlined design is ideal for applications where space is limited or a flange could interfere with nearby components.
Our caps and plugs with a flanged base offer an easy gripping point for installation and removal. When used as plugs, the flange helps prevent the part from being pushed too far into the opening.
Our caps and plugs with a pull tab base provide a convenient gripping point for quick, easy removal. The tab helps you pull the part free, especially in tight or hard-to-reach spaces.
Choose from five stock colors to help identify lubrication points and organize maintenance. Additional and custom colors are also available for larger orders, subject to minimum order quantities.
Sample packs are available for each and every size of our caps and plugs making sure you're getting exactly what you need before making a full purchase.
