Flare Kit

These kits connect copper refrigeration tubing to the mechanical equipment by means of a permanent mechanical seal to a JIS B 8607 Class 2 Flare Stub. To ensure equipment compatibility, this kit is designed to utilize the factory Flare Nut provided with the original equipment.

The fitting is ETL listed for U.S. and Canada with an allowable working pressure of 1500 PSIG per UL-207. The copper flare stub allowable working pressure is equal to the annealed copper tube rating by tube size per ASME B31.5. The fitting is intended for use with C12200 Type L copper tube conforming to dimensions of ASTM B280. All tempers of copper tube may be used (O60, H55, H58). Fitting may also be used with C19400 copper alloy.
