2" stainless ferulle brazed with a special flux coated 45% pure silver solder to a copper slip joiner. These fittings have been requested by the home builders to allow easy joining of copper to tricalmp fittings.
Use one of these, slip a 2" copper pipe in, true it up and either braze or soft solder your pipe in to fit instantly to a keg or any other 2" triclamp fitting.
Use in conjuction with our ferulle to keg 2" gasket for kegs or plain 2" gasket for other ferulles.
Professionally brazed and polished.
