Is Copper Bulkhead Pressure Fitting The Right Product For My Application

Have a shallow sheet metal pan that is being used to boil down maple syrup. Need to run a pipe into the side to drain off the syrup as it boils down. Is a copper bulkhead pressure fitting the right thing to use for this purpose?

 

The copper bulkhead fitting will have to be mounted a bit above the bottom of the pan to allow for the gasketed surface on the inside portion and will leave a certain depth of liquid in the pan.
If you can scoop out the remaining liquid this might be ok.
There are several types of bulkhead fittings and there may be a type more suitable for what you want to do and you could consider munting o to the bottom of the pan if the heat does not affect it.
Marine bulkhead fittings for example.........you just need to make sure the threads go all the way to the flange and that the gasket can take the heat and be suitable for food processing.

The proper way to do this would be to use lead free solder or silver braze an outlet tube flush with the bottom to drain all the liquid.

 

A tube had been soldered to the pan but leaked. I thought the bulkhead fitting might be more secure.

 

Did the soldered tube completely drain the tank?
If it leaked it probably could be soldered and might be a better option than a bulkhead fitting.

A clear picture of the tank and current fitting might help us help you.
