A small investment to insure your Mini-Split is installed leak free! This Mini-Split Kit is popular for connection sizes for nominal BTU rating Mini-Splits of 7,000 BTU, 9,000 BTU and 12,000 BTU. Please check your products connection sizes to verify. This Kit contains (2) 1/4” FlareSeal® and (2) 3/8” FlareSeal®.
FlareSeal is a copper multi-ring seal coated with a proprietary Loctite® coating specific to the Air Conditioning / Refrigeration industry. It is a next generation product that can handle all the new oils and refrigerants. The flare seal snaps securely onto the male flare fitting and once the flare nut is tightened, the connection becomes a confident leak free connection every time.
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.
