I have an aluminum filter housing that needs to connect to a pumped drain system made of copper. When the system is in use, it will operate at about 140F. Thread size is 2" NPT.
What connection should I make between the two materials? I'm concerned about threaded joint leakage due to differing expansion coefficients, as well as possible galvanic action.
