Straightflow - Vband Connector D127/5.0 inch

The stainless steel V band D127 (5.0 inch) connector set is a professional-grade solution for secure and serviceable exhaust system connections. Designed for high-performance and large-diameter exhaust applications, this kit includes precision-machined male and female flanges together with a heavy-duty V-band clamp.

Manufactured from premium 304 stainless steel, the connector provides excellent resistance to corrosion, oxidation, and extreme exhaust temperatures. It is engineered to withstand demanding conditions commonly found in turbocharged engines, motorsport vehicles, and custom performance builds.

The V-band connection system ensures perfect alignment between exhaust components while distributing clamping force evenly around the entire flange surface. This design improves sealing reliability and minimizes the risk of exhaust leaks compared to traditional multi-bolt flange systems. It also allows faster installation and easier disassembly, which is especially important for turbo systems requiring regular maintenance or adjustments.

With a 127mm (5.0 inch) diameter, this connector is intended for large exhaust piping used in high-horsepower applications. Accurate measurement of the pipe’s outer diameter is recommended before welding to ensure proper fitment and optimal sealing performance.

The stainless steel construction ensures long service life even under continuous exposure to vibration, heat cycles, and aggressive environmental conditions. The precision-machined sealing surfaces help maintain consistent contact pressure, contributing to a durable and leak-free joint.

This connector set is suitable for professional fabrication projects, turbo manifold outlets, downpipe connections, and custom exhaust systems where strength, reliability, and serviceability are essential.
