Flanges
A quality flange is the foundation of a leak-free, strong connection in your exhaust, turbo, or intake system. Our flanges collection brings together a wide range of styles, sizes, and materials to support everything from OEM replacement to custom fabrication work.
Whether you're building a downpipe, welding up an intercooler pipe, or replacing a corroded exhaust flange, you'll find options here that match your project. Key considerations when choosing a flange include:
- Bolt pattern and inner diameter — match to your piping and mating component
- Material — mild steel, stainless steel, or aluminum depending on heat and corrosion needs
- Thickness — thicker flanges resist warping under high heat cycles
- Type — flat, stepped, or v-band; each suits different sealing and alignment methods
Browse the collection to find the exact flange you need, and pair it with the proper gasket and hardware for a reliable assembly that lasts.
