These silicone thread plugs seal internal threads across their full length prior to coating. They maintain dimensional stability in curing ovens up to 315 °C and are recommended by the manufacturer for liquid paint, e-coating (KTL), anodizing, and electroplating as well.\u003c\/p\u003e\n\u003cp\u003eImportant distinction: plastic thread plugs sold as end caps for furniture tubing, square tubing, or chair legs will melt in the curing oven.

Over its length of 25.4 mm, it tapers by only about 2 mm.
