Build With Confidence From The First Connection

When you’re building a custom exhaust or turbo system, every part has to pull its weight, literally and figuratively. The PPE 3 inch Engine Side Aluminum V-Band Flange gives you a strong, lightweight starting point that’s made to simplify your fabrication while delivering long-term reliability. It’s perfect for builders who want a clean, professional-grade setup without fighting alignment or worrying about weight. The interlocking design takes the guesswork out of fitment, letting you focus on getting solid welds and a leak-free seal. Whether you’re routing tubing through a tight bay or chasing every ounce for a race setup, this flange fits right into the plan. It pairs seamlessly with PPE V-band clamps to give your system a secure, serviceable connection. From mockup to final pass, this flange helps your build feel solid, clean, and built to last.

Precision Fabrication Starts With A Properly Aligned Flange

The PPE 517230001 flange is designed specifically for engine-side applications using 3 inch aluminum tubing, delivering the kind of precision and reliability custom builders depend on. Its machined interlocking profile ensures a tight and consistent alignment during welding, which is critical when sealing against pressure, temperature spikes, and vibration. Constructed from corrosion-resistant aluminum, the flange offers both durability and weight savings, perfect for high-performance setups that demand both strength and agility. It’s engineered to work in conjunction with PPE’s V-band clamp system, allowing for a tight, repeatable seal and straightforward installation. This flange is ideal for turbocharged engines or large displacement builds where 3 inch tubing is commonly used and space can be limited. The universal fit makes it a flexible option for a wide variety of custom fabrication jobs. With the right weld and pairing, this flange becomes a foundational piece of your performance system.
