Our newest addition to our Back Purging line up, high temp silicone back purging plugs. These work well when not welding in close proximity to the plug, and can withstand up to 600 degrees. We recommend keeping these 2-4 inches from the area being welding. If you will be welding closer to the plug, we recommend our aluminum purge plugs which work with any heat range.
With these high temp silicone plugs we have added a barb, internal diffuser, and vent fitting. The barb is short to prevent pulling out of the plug as the pipe/tube is moved and repositioned. The diffuser will help distribute the argon smooth and even through the tube/pipe. Our vent fitting will properly vent out the opposite end of where you are welding.
We have also adapted these to our new quick disconnect kits making the back purging process even easier. Our quick disconnect kits also work with the silicone plugs as well and are available on our main back purging page.
Below we have a detailed fitment guide of the sizes each plug will fit. Select the size or sizes that best suit your back purging needs. They are labeled A-F for a quick reference. If you purchase a full kit you will get FREE SHIPPING.
