Purge plugs play a vital role in TIG welding by protecting welds from contamination. They help create a clean, oxygen-free space inside pipes during welding.
These plugs seal pipe ends tightly to allow inert gas to flow inside. This gas protects the weld area from air and moisture, preventing weak spots and corrosion. Made from high-temperature silicone, purge plugs resist heat and fit various pipe sizes.
Kits include multiple plugs and fittings for different welding needs. Using purge plugs improves weld quality and strength, especially in stainless steel and alloy pipes. Choosing the right size and type ensures proper sealing and gas flow. For fabricators working on exhausts, headers, or manifolds, purge plugs help achieve smooth, clean welds every time. They are simple tools that make a big difference in TIG welding results.
