Ticon 903-71000-1000 2.5-4in Silicone Purge Plug Kit TIG Welding Exhaust System

Vehicle Fitment

• Universal Fabrication Tool Kit. Designed for back-purging 2.5-inch, 3.0-inch, 3.5-inch, and 4.0-inch O.D. tubing in TIG welding applications.

Fitment Notes

• This kit is specifically tailored for common exhaust system tube diameters.
• Must be installed at least 1 inch away from the weld joint to prevent damage to the high-temperature silicone.
• Plugs are compatible with Ticon Industries/TIG Aesthetics Quick Disconnect Shower Diffusers (sold separately).

Features

• Comprehensive kit covers the most common exhaust pipe sizes from 2.5 inches through 4.0 inches.
• Manufactured from high-temperature silicone that can withstand extreme heat from the weld seam.
• Each plug incorporates a multi-layer stainless steel diffuser to eliminate argon gas turbulence.
• Diffuser technology maximizes the efficiency of argon consumed, saving on gas costs.
• Hyper lightweight titanium 0.5mm wall argon inlet tubes provide a non-contaminating gas entry point.
• Provides a perfect, leak-free seal inside the pipe to ensure a contaminant-free welding environment.
• Color-coded plugs (Yellow, Green, Cyan, Blue) allow for quick size identification during fabrication.
• Essential for achieving professional, high-integrity welds on materials like titanium, stainless steel, and inconel.

Product Description

The Ticon Industries 903-71000-1000 Silicone Purge Plug Exhaust Kit is the professional fabricator's all-in-one solution for high-quality TIG welding of exhaust systems. This comprehensive kit provides the necessary components to back-purge the four most common exhaust pipe diameters: 2.5", 3.0", 3.5", and 4.0" O.D. Back-purging is a mandatory process for welding exotic materials like titanium and stainless steel, as it prevents atmospheric oxygen from contaminating the molten weld pool on the backside, which otherwise leads to "sugaring" and structural degradation.

Each of the eight high-temperature silicone plugs is designed to create an immediate, perfect seal, allowing the introduction of inert argon gas. Crucially, every plug features a multi-layer stainless steel diffuser, which carefully manages the argon flow. This proprietary diffuser eliminates gas turbulence and ensures a smooth, non-disruptive blanket of gas inside the pipe, maximizing efficiency and drastically reducing the consumption of expensive argon compared to makeshift solutions.

This kit is built for durability and precision, featuring hyper lightweight titanium argon inlet tubes that are resistant to heat and contamination. By offering four distinct sizes, the 903-71000-1000 kit eliminates the guesswork and waste associated with using tape or foil, delivering consistent, beautiful, and structurally sound welds across a wide range of motorsports and industrial applications. This universal tool is a critical upgrade for any fabricator serious about achieving zero-defect pipe welding.
