SILICONE PLUGS

R&B Welding Applications silicone plugs are temperature resistant to 500°F (260°C). They can be used for sealing during transport and storage. During pre-warming, welding and heat treating they can be used to keep out unwanted air. They can be supplied with or without a hole for use with Diffuser #1 through Diffuser #3.
