See the solution in real use and note how it behaves under normal conditions. In this video, we demonstrate the Shuxin silicone rubber tapered plug stoppers in action during high-temperature powder coating masking. Watch as we test their sealing performance, heat resistance up to 300°C, and ease of use across various hole sizes. Learn how these durable plugs protect holes during industrial processes like painting, hydro dipping, and media blasting.
