Wehrli O-ring for the LBZ/LMM Duramax two-piece Y-bridge inlet seals the inlet pipe to the cast two-piece bridge on 2006–2010 LBZ and LMM applications. Specified for use in WCFab Y-Bridge kits and stage bundle kits from those years, this replacement O-ring restores the sealing surface between the inlet pipe and bridge base on custom or replacement Y-bridge assemblies.
