Tial 50mm Blow Off Valve Weld Flange for 4.00in

The Tial 50mm Blow Off Valve Weld Flange for 4.00in by Vibrant Performance is engineered for turbocharged and supercharged engines that require controlled boost relief without sacrificing intake tract integrity. This weld flange adapter serves as the mounting foundation for Tial's industry-leading 50mm blow-off valve, designed to vent excess boost pressure during throttle lift-off while maintaining a sealed system that prevents boost loss. Whether you're building a street performance platform or preparing a track-focused machine, this component is essential for any forced-induction system that demands reliable, adjustable pressure relief.

Constructed from high-quality materials rated for sustained boost cycles, the Tial 50mm blow-off valve flange features a precision-machined weld interface designed for secure, permanent installation on 4.00-inch intake piping. The 50mm valve bore provides optimal flow characteristics that match modern turbocharger output while the weld-flange design eliminates connection failures common to bolt-on adapters under high-frequency boost cycles. The compact dimensions (5.12 x 1.57 x 6.69 inches) and minimal weight ensure easy integration into tight engine bay configurations without adding unnecessary mass to your intake system. Vibrant Performance's reputation for precision fabrication ensures this flange meets strict tolerances for perfect valve seating and repeatable operation across boost ranges.

Technicians and enthusiasts building custom turbo applications on domestic or import platforms will find this weld flange indispensable for achieving controlled boost management without atmospheric bypass loss. Installation requires welding the flange directly to your 4.00-inch diameter intake piping, creating a permanent, vibration-resistant connection ideal for high-boost applications exceeding 20 psi. Proper sizing of this 50mm flange for your 4.00-inch pipe ensures maximum flow efficiency and prevents backpressure that can compromise turbo spool characteristics. This component pairs seamlessly with Tial's complete blow-off valve lineup and works across a wide range of engine displacements and turbocharger combinations.
