Audi Exhaust Gasket – Manifold to Header Pipe 443253115A – Elring 694614

Exhaust pipe flange gaskets are used to make an airtight seal between exhaust system sections. These gaskets are often used between header sections and catalytic components. Depending on application, exhaust pipe flange gaskets are most often flat and ridged, made of metalized cardboard or crushable metal. Exhaust pipe flange gaskets are a common point of failure in the exhaust system and should be inspected when the tone or volume of the exhaust changes. Because these parts are common failure points and often designed as one time crush-to-seal parts, it is a good idea to replace these seals when an exhaust component is being repaired or replaced.
