Designed for industrial tube use, the new rubber seal plug takes into account the specific requirements of HVAC and medical professionals, as well as individuals from other trades, says the company. It has a tapered end to ensure a snug fit in even tight spaces. The non-staining rubber won’t damage copper, aluminum, or other metallic tubing. The plug fits in with the company’s current line of rubber seal plugs with tabs.
