- Country of origin: United States.
The EGR valve gasket seals the joint where the EGR valve meets its mounting surface so recirculated exhaust gas stays contained. Over time the gasket can harden or blow out, which may allow a leak at that connection and show up as a rough idle or an EGR-related trouble code. If a failed gasket is the cause, this replaces it, and fitting a fresh gasket is recommended any time the EGR valve is removed for service.
