Strictly Modified Welding Back Purge Plugs .5" - 1" Pipe & Tube (set of 4)

We have added a new addition to our Back Purging Product Line. We have now added .500" - 1" Back Purging Plugs to our line up. These work great on smaller diameter tube/pipe as well as as 02 bungs or any other type of smaller weld bungs. They also work great on aluminum bungs 1/4" NPT and larger as a heat sink to pull heat away from bungs while welding. These our our favorite Purge Plug so far as they can be used in so many different applications. If you are welding Stainless Steel, Titanium, or any other type of exotic metals back purging is a must. If you are welding tube/pipe from .5"-4" we got you covered with our extremely quick and simple way to back purge. Our Back Purging Plugs can be used for manifold fabrication, collectors, dump tubes, custom exhausts, headers, intercooler pipes, 1/4" and larger weld bungs and much more. Can also be used for sanitary welding, the uses are endless. We have personally used and tested all of these plugs extensively and work flawlessly. To aid removal we had flats machined on the top of the plug. Just tap them in to the pipe/tube/bung, and they lock into place. To remove, just put and wrench on and crack them loose, or just tap the flat on top of the plug and they pop right out.
