Product Description
MAHLE F31910 EGR valve gasket restores a tight, heat-resistant seal on 2006–2010 GM 6.6L Duramax LBZ/LMM engines. Built with OE-style multi-layer steel (MLS) construction, it seals the exhaust manifold to EGR inlet pipe junction (inline bolt holes) to help prevent exhaust leaks, soot streaking, and lost turbo response on daily, tow, and fleet trucks.
Fitment
- 2006–2007 Chevrolet/GMC 2500HD/3500HD 6.6L Duramax LBZ
- 2007.5–2010 Chevrolet/GMC 2500HD/3500HD 6.6L Duramax LMM
- Position: Exhaust manifold to EGR inlet pipe (inline bolt holes). Sold individually.
Cross-Reference / OE Notes
- Direct-fit replacement for the manifold-to-EGR inlet pipe gasket used on LBZ/LMM platforms
- Material: Multi-layer steel (MLS)

FAQ
Will F31910 fit both LBZ and LMM?
Yes. It’s listed for 2006–2010 LBZ/LMM 6.6L applications at the manifold-to-EGR inlet pipe location.
What’s the material?
Multi-layer steel (MLS) for high heat and pressure sealing.
Is this the same as the EGR tube-to-valve gasket?
No. That’s a different location (see MAHLE F31909). F31910 is for the manifold to EGR inlet pipe with inline bolt holes.
