WOW!!!!! Sorry, I thought you were talking about a pipe or tube fitting.....
Better Post a picture !!....
Are you talking about the Pre-Heat tube for the air cleaner ?? This is a flexible tube that directs heated air to the intake of the air cleaner. This should be Heated air from Around the outside of the exhaust manifold and should NOT have Exhaust gasses or pressure leaking out, or noise.
