Rated 5 out of 5 stars.
Here's a must-have tool for any serious fabricator or welder.
This is a 3.5-inch Tial-style V-band back purge block and heat sink, expertly machined right here in the USA by Winters Machining LLC.
It's designed to fit perfectly into a 3.5-inch V-band clamp.
When you're welding, you can slide this block in to act as a heat sink, protecting the surrounding area from warping.
More importantly, you can use it to introduce argon gas for back purging, ensuring a clean, strong weld on the inside of your tubing.
It's a solid, precision-machined piece that will make your stainless steel and titanium welding jobs come out cleaner.
Brand new and ready to work.
