Tial 50mm Blow Off Valve Weld Flange for 2.50in

The Tial 50mm Blow Off Valve Weld Flange for 2.50in is a precision engineering solution designed for turbocharged and supercharged engine builders who demand reliable boost control and consistent performance. This weld flange adapter bridges the gap between your turbocharger's compressor outlet and a 50mm blow-off valve, enabling seamless integration into custom intake manifold or charge pipe fabrication. Whether you're building a street car, track vehicle, or high-horsepower engine swap, this component ensures your blow-off valve mounts securely at the exact angle and position your system requires.

Manufactured by VIBRANT PERFORMANCE under part number 10137, this weld flange features a robust design engineered to handle boost pressure cycles without flexing or warping. The 50mm diameter opening matches OEM and aftermarket blow-off valves, while the 2.50-inch port opening accommodates standard charge pipe sizes used in modern turbo platforms. Constructed from durable aluminum or steel (depending on application), the flange is designed to be welded directly into your custom piping or manifold, creating a permanent, leak-free connection that eliminates the need for clamps or adapters at this critical junction. The compact 5.12 x 1.57 x 6.69-inch profile ensures minimal interference with engine bay components and tight custom fabrication layouts.

This weld flange is ideal for fabricators, engine builders, and enthusiasts custom-fitting blow-off valves to non-standard platforms or adapting turbo systems to different inlet sizes. Proper installation requires TIG welding equipment and basic metalworking skills to ensure a clean, strong weld that maintains boost integrity under load. Compatible with all 50mm blow-off valves from Tial, HKS, Turbosmart, and similar manufacturers, this flange simplifies plumbing on projects where bolt-on solutions don't fit the layout. Weighing just 0.21 lbs, it adds negligible mass while providing the structural foundation your boost control system depends on for reliable venting and boost regulation across the entire RPM range.
