Motorsport Fab Purge Diffuser Set

Motorsport Fab Purge Diffuser Set

The Motorsport Fab Silicone Purge Plug Kits are designed by fabricators for fabricators and are used for shielding the inside of the weld with an inert gas to prevent contamination during the welding process, resulting in a stronger, smoother weld. Our diffusers are a key component to making this happen, add more of them to your toolbox so you don't have to change them out as often.



  • Designed by fabricators for fabricators
  • Billet argon diffuser head 
  • Billet purge adjustable regulator 
  • Blue anodized



As a true fabrication company, Motorsport Fab has the advantage of looking at existing holes in the market & designing products that provide the fabricator with tools and products that allow them to create their best work. 

Our Diffuser adapters are CFD designed to distribute the argon gas perfectly throughout the tube being welded. The purge regulator goes on the other side of the tube and allows you to regulate the flow amount through the tube being welded. This allows you to control the perfect amount of argon at all times.


  • 1 billet diffuser
