InterPuge silicone tapered 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.
Available in various colors and sizes, these silicone tapered plugs are essential pieces of equipment for sealing off gases or liquids prior to welding or other heat-treating processes. Contact us at Intercon if you have any questions about which type of plug is the right one for your job.
