3in V-Band Clamp Flange 304 Stainless

The 3in V-Band Clamp Flange 304 Stainless by PYPES PERFORMANCE EXHAUST is a precision exhaust coupling system engineered for high-performance engine builders, turbo installers, and custom fabricators who demand reliable, leak-free connections. V-band clamps have become the gold standard in modern exhaust design because they eliminate the need for multiple bolts and gaskets, providing tool-free assembly and disassembly while maintaining structural integrity under extreme heat and vibration. This 3-inch diameter flange is an essential component for anyone building a forced-induction system, upgrading stock exhaust plumbing, or constructing a custom turbo manifold setup.

Manufactured from 304 stainless steel, this flange resists thermal cycling corrosion and maintains its clamping force across repeated heat expansion and contraction cycles—critical for turbo applications where exhaust temperatures routinely exceed 900°F. The v-band design creates a mechanical wedge lock that distributes pressure evenly around the circumference, eliminating hot spots and leak paths that plague traditional flanged connections. At 1.4 lbs and compact dimensions of 6 x 2 x 6 inches, the flange integrates seamlessly into tight engine bays while the stainless material ensures longevity in environments where mild steel would pit or crack within seasons.

This flange pairs with standard 3-inch v-band clamps (sold separately) and works across naturally aspirated and turbocharged applications—from LS swaps and small-block builds to diesel downpipe modifications. Mechanics and fabricators appreciate the reusability; clamps can be removed and repositioned without sacrificing seal integrity, making this the preferred choice for prototype testing, competition builds, and quick-change exhaust systems. Whether you're flowing more CFM through a custom header or connecting turbo inlet pipes, the PYPES HVB30 delivers the precision engineering and material quality that separates professional-grade exhaust work from amateur guesswork.
