SFL Series Silicone Flangeless Plugs are designed to mask threaded holes without masking the surrounding area while undergoing painting, plating, powder coating, anodizing, abrasive chemical processing, or exposure to high temperatures. The tapered design allows for many different size holes to be masked using one size plug, and also offers a pull-tab for easy removal. The SFL Series is available in an assortment of colors for easy identification.
