I need to purchase a part for my Hummer H3 2006 but I don't know its name in English. The part is a sort of gasket that is used on the attached item which also I don't know the name. Would you please assist in this very much needed question
You need an "exhaust flange gasket" or "Doughnut gasket" it is a semi-soft gasket made out of a lead composite material and will crush to seal between two flanges. This gasket is located between the exhaust manifold and the catalytic convertor.

You should be able to get it for $12.00 or less on line
I can answer questions pertaining to military HMMWVs. I can also answer questions on other military trucks to include M35A2, M800 5tons,M900 5tons, M916 CUCV, HEMMT, M113A2, M113A3 and miscellanous ground support equipment. I cannot answer questions about civilian Hummers; they are very different from their military counterparts.
I have been a mechanic in the military for 16 years.
