MAHLE Victor Reinz (MAHLE Original gasket line) F31909. OE-quality sealing component/set for diesel engine service.
Replace a leaking EGR connection and need a reliable gasket to restore proper exhaust sealing? This MAHLE Gasket provides a tight, leak-free seal between the EGR tube and the EGR valve. When the original gasket becomes heat-damaged or compressed from repeated thermal cycles, exhaust gases can escape, leading to soot buildup, reduced turbo efficiency, or EGR-related trouble codes. Installing the F31909 restores proper exhaust gas routing and helps maintain efficient operation of the emissions system on GM 6.6L Duramax engines. Built to meet or exceed OE specifications, the MAHLE F31909 features a durable steel gasket construction that withstands extreme exhaust temperatures, pressure pulses, and vibration. Precision stamping ensures consistent sealing pressure between mating surfaces while resisting distortion during repeated heat cycles. Engineered for direct-fit installation, this gaske
Notes: Follow MAHLE torque/installation specs. Replace one-time-use fasteners as required. Preserve factory emissions equipment; this listing is not an EGR delete or block-off kit.
