Product Details
This is a replacement O-ring seal from Wehrli Custom Fabrication, designed for the VGT turbo inlet on Duramax engines from 2004.5 through 2016. It's also used on specific WCFab Y-bridge kits for LB7 models. A good O-ring seal is crucial for preventing air leaks, which can hurt performance and efficiency.
This particular seal is used in several WCFab kits, including their Legacy S400/Stock twin kits, Stage 2 intake kits, and VGT Turbo Inlet Horns. If you're working on one of these setups and need to replace a worn or damaged seal, this is the part you'll need. For the LB7 Billet Y-Bridge Kit (WCF100693), you'll need two of these seals for installation on the intake runner flanges.
