-The middle shaft of the throat is made of titanium alloy, which makes the inner pipe wall smoother and has better heat insulation effect.
-The threaded part is made of copper, which speeds up the heat dissipation. Reduce plugging.


The copper heat dissipation effect is better than that of Aluminum.
