4in Aluminum V-Band Flange Assembly Each

The 4in Aluminum V-Band Flange Assembly Each from VIBRANT PERFORMANCE is a precision coupling component engineered for high-performance exhaust, intercooler, and intake systems where quick-disconnect capability and leak-free sealing are essential. This V-Band clamp assembly is designed for technicians and enthusiasts building or maintaining turbo systems, custom exhausts, and forced-induction applications that require reliable, reusable connections without permanent welding. The modular nature of V-Band assemblies makes them ideal for systems that need frequent service, testing, or reconfiguration.

Constructed from lightweight aluminum, this 4-inch OD tubing flange incorporates an integrated O-ring seal that ensures positive pressure retention and eliminates the need for additional gasket material or sealant compounds. The V-Band design uses a tapered wedge clamping mechanism that distributes load evenly across the flange face, reducing stress concentration and preventing warping or leakage under thermal cycling and vibration. The natural aluminum finish provides corrosion resistance suitable for most underhood environments, though powder coating or ceramic protection can be applied if operating in extreme salt or chemical exposure conditions. Each assembly is sold individually, allowing builders to purchase matched pairs for dual-inlet or multi-stage configurations.

This component is most beneficial for turbocharger installations, custom intake manifold fabrication, and modular exhaust system development where standard flanges would be difficult to machine or where system disassembly must be quick and damage-free. Installation requires matching the flange OD to your 4-inch nominal diameter tubing and securing both halves with a compatible V-Band clamp band (sold separately). The O-ringed design eliminates the guesswork of gasket selection and improves reliability in high-boost or high-temperature applications. Builders, performance shops, and engine tuners standardize on V-Band assemblies to reduce turnaround time on dyno testing and facilitate rapid prototype validation.
