Fits: 2006-2010 GM Duramax; see application.
MAHLE Victor Reinz (MAHLE Original gasket line) F31912. OE-quality sealing component/set for diesel engine service.
Is it time to repair an EGR system leak? The MAHLE EGR Valve Gasket is an OE-style replacement designed to seal the connection between the EGR valve and EGR cooler assembly. Over time, extreme exhaust heat and repeated thermal cycling can cause the original gasket to degrade or compress, allowing exhaust gases to escape and potentially causing soot buildup, rough engine operation, or emissions system faults. Installing the F31912 restores a tight seal and helps maintain proper EGR function on GM 6.6L Duramax engines. Manufactured to meet or exceed original equipment specifications, the MAHLE F31912 features a durable steel gasket construction that withstands high exhaust temperatures and pressure fluctuations within the EGR system. Precision stamping ensures accurate alignment and consistent sealing pressure between mating surfaces, helping prevent leaks even under demanding diesel opera
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.
