Made from a premium silicone compound, the plugs resist temperatures up to 600°F (315°C) for at least 20 minutes and tolerate many common chemicals used in surface treatments. Color coding on each size speeds selection and prevents mix-ups during production or shop work, while the tapered profile ensures a snug, reliable seal in bore holes and tubes.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these XL silicone plugs perform during high-temperature powder coating?\u003c\/h3\u003e\n\n\u003cp\u003eThese plugs are formulated to withstand the elevated temperatures and brief bake cycles typical of powder coating. They retain shape, won’t crack or become brittle, and provide a consistent seal that keeps interiors and threaded areas free of coating overspray.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eRated for short-term exposure to 600°F (315°C).\u003c\/li\u003e\n\u003cli\u003eTapered design creates a tight interference fit in 0.750\"–1.437\" ID holes.\u003c\/li\u003e\n\u003cli\u003eColor coding matches sizes for quick identification on the bench.\u003c\/li\u003e\n\u003cli\u003eReusable across multiple coating cycles without hardening.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these plugs resist chemicals used in plating, anodizing, or media blasting?\u003c\/h3\u003e\n\n\u003cp\u003eThe premium silicone used in this set shows good chemical resistance to many common shop fluids and cleaning agents encountered during plating, anodizing, and media blasting.
