Ticon 903-71076-0000 2.5in Tube Silicone Purge Plugs TIG Welding Back Purge Set

Vehicle Fitment

• Universal Fabrication Tool. Used for back-purging 2.5-inch (63.5mm) O.D. tubing in TIG welding applications.

Fitment Notes

• Designed for use with standard 2.5-inch O.D. tubing for custom exhaust, turbo, and charge pipe fabrication.
• Compatible with TIG Aesthetics Quick Disconnect Shower Diffusers (sold separately).
• Place the plug at least 1 inch away from the weld joint to protect the silicone from excessive heat exposure.

Features

• Constructed from durable, high-temperature silicone elastomer compound.
• Includes an internal multi-layered stainless steel diffuser to distribute argon gas evenly and eliminate turbulence.
• Creates a positive, airtight seal at the pipe opening to maintain a pure, inert environment for welding.
• Equipped with a titanium-barb inlet fitting for secure and reliable attachment of the argon supply hose.
• Rigid internal core prevents the plug from deforming or collapsing when inserted into the tube.
• Optimized design significantly reduces argon consumption compared to traditional back-purging methods.
• The bright Cyan color provides high visibility for easy retrieval from long or intricate tubing runs.
• Highly reusable and built for the demands of a professional fabrication environment.

Product Description

The Ticon Industries 903-71076-0000 Silicone Purge Plug is an essential tool for achieving professional-grade TIG welds on 2.5-inch O.D. pipe and tubing. When welding critical materials like stainless steel or titanium, exposure to oxygen on the backside of the weld (the "sugaring" effect) can lead to structural failure and poor aesthetics. This plug solves that issue by creating an isolated chamber filled with inert Argon gas - a process known as back-purging.

The plug is engineered using a robust, high-temperature resistant silicone material that forms a perfect seal inside the pipe. Its internal design incorporates a stainless steel diffuser, which is a significant upgrade over basic plugs. This diffuser ensures that the incoming argon is distributed gently and evenly, preventing gas turbulence that can pull in ambient air. This efficiency not only guarantees a flawless weld bead interior but also leads to substantial savings on costly Argon gas over time.

Sold as a pair, these 2.5-inch plugs are designed for the complete sealing of both ends of the tube being worked on. They feature a rigid structure for easy insertion and a secure titanium-barb inlet for connecting the gas line. This universal fabrication system ensures that fabricators working on high-performance exhausts, charge pipes, or manifold runners can consistently produce welds that are structurally sound and aesthetically superior without interior contamination.
