Silicone Plugs

InterPuge silicone plugs are temperature resistant to 500 F (260 C) and can be used for sealing during transport and storage. They can also be used for sealing against unwanted air during pre-warming, welding and heat treating. Any diffuser from No. 2 to No. 3.5 can be used with a plug for a purging application by simply drilling a 1/4" (6 mm) hole through the center.
