Plastic Caps and Plugs

Plastic Caps and Plugs

Shop a wide variety of plastic caps and plugs. Round caps, short or long, fit over rods, or cover ends of parts. Square caps and angle caps are other styles that protect. Round caps with square ends prevent rolling and round caps with hanging features are available. Round caps designed with tabs to enable the removal of the cap come in multiple styles. There's even a cap that could also serve as a plug! Materials vary, with the most common PVC. Our in-house chemist has created numerous formulas that give us the option to produce end products that are very flexible or very firm. Additional formulations can yield materials that are able to tolerate high temperature levels. This can often make this material choice better than more expensive rubber caps. (See our material selection guide. https://www.stockcap.com/material-selection.html.) Dip molded caps like this allow us to create a single diameter cap at multiple lengths from the same mold.
Injection molded caps are commonly made from low density polyethylene, LDPE and we stock many styles and sizes in red, with other colors available upon request.
