Nu-CalgonThermo-Trap, 11 oz. Tube

Use it all the time for brazing new valves and lines in on the TK reefers we service. Works better than the wet rag method, and offers excellent protection when installing heat sensitive components like TXVs. 10/10

Don't use cold rags when brazing. Just put on thermo trap and growth it. ive used it for years. no complants.
