This product is great for people who need to make pressurized transfers in FTSs or Brew Buckets. You can use it to add a 1.5' TC flange to almost any vessel. It has a weldless design, which makes it easy to use. The fitting is made of 304 stainless steel, so it's durable. It comes with a high heat compatible silicone O - ring. You'll need a TC Clamp and Gasket to use it, and a 42 mm carbide hole saw is recommended for installation.
