Expanding Purge Plug
The Expanding Purge Plug is a reliable mechanical sealing solution designed for localized gas purge applications during stainless steel pipe welding.
The product consists of a heat-resistant silicone body, stainless steel pressure discs and a manual expansion mechanism. By tightening the integrated wing nut, the silicone body expands evenly inside the pipe, creating a secure and airtight seal while allowing controlled gas delivery directly to the purge zone.
Key Features:
• manual mechanical expansion system;
• integrated 6 mm gas fitting;
• fast installation and removal;
• excellent airtight sealing performance;
• secure fit inside the pipe;
• reusable heat-resistant silicone construction;
• stainless steel pressure discs;
• suitable for multiple pipe diameters with up to 5 mm expansion per size.
Benefits:
The Expanding Purge Plug creates a strong and reliable seal inside the pipe, minimizing purge gas leakage and maintaining a stable inert atmosphere throughout the welding process.
The mechanical expansion system allows operators to install and remove the plug within seconds without additional tools. The secure sealing helps reduce gas consumption while improving purge efficiency and overall weld quality.
Its durable construction, reusable design and simple operation make the Expanding Purge Plug an ideal solution for industrial stainless steel pipe welding, orbital welding and high-purity fabrication applications.
