Our seal protects against the primary area of flare fitting leaks on the sealing surface. FlareSeal® fits all common SAE flare connections for our industry. It not only provides a long-term leak-free connection on new installations or products, but it also can be used to stop weeping connections in existing systems.
I pulled a vacuum and got a 134 microns. I worried about that and purchased and installed the Flareseal ®. After that I got a 96 micron on the vacuum hold test. I am sold on theses little gems.
