Assembly: 

 

Threaded fittings 

The Therminator

TM 

utilizes ½” NPT (National Pipe Taper) male threads for the wort side of the exchanger

 

(top fittings on the back and front of the exchanger) that will readily mate up with your preferred type of 
hose connector. The cooling water side of the exchanger (bottom fittings on the back and front of the 

exchanger) is fitted with ¾” male garden hose threads (GHT).

 High quality hose quick connect fitting 

adapters from Blichmann Engineering are available through your retailer. 

 

Caution: 

If you are using stainless NPT adapter fittings on the wort side of the exchanger (½” NPT) it is

 

necessary to use a thread sealing tape (Teflon

TM 

type) to prevent thread galling (welding), which is not 

covered under warranty. If you feel any grinding while tightening stop immediately as this galling the 
threads! Threads, once galled, will not come apart! The key to long thread life is not over tightening, and 
using an adequate amount of thread sealing tape.  If you are using brass or plastic adapter fittings, the use 
of thread sealing tape is still recommended, but optional. No sealing tape is needed on the cooling water 
side of the exchanger since it employs non-tapered garden hose threads.
