Wehrli S400 Compressor Outlet O-Ring Seal

This O-ring seal is made from a material that can handle the heat and pressure found around the outlet of a Borg Warner S400 turbocharger. It's specifically designed to fit the V-band flanges on the compressor cover outlet, ensuring a tight seal when you're installing or servicing your turbo setup.

When you're working on a custom turbo application, especially with an S400 turbo, getting all the seals right is crucial for preventing leaks and ensuring your system performs as it should. This part from Wehrli Custom Fabrication is a direct replacement for the factory O-ring, meaning it fits right into place without any fuss. It's a small but important piece that helps keep your exhaust gases contained where they belong.

This O-ring is commonly used in various WCFab turbo install kits for Duramax and Cummins engines, making it a reliable choice for those specific builds. Having a fresh O-ring on hand can save you time and headaches during installation.
