3.5" V-Band Clamp Assembly (Mild Steel Rings / SS Clamp). The heavy-duty fabricator’s choice for large-diameter high-flow exhaust systems. Get the weldability of mild steel flanges paired with the long-term corrosion resistance of a high-strength stainless steel clamp assembly.
- Weld-Ready Flanges: Mild steel rings offer a superior, consistent weld profile when attaching to standard steel tubing—perfect for drift and track-day fabrication.
- Durable Stainless Clamp: The clamp assembly resists extreme heat cycles and road-side corrosion, ensuring your system remains serviceable for years.
- The "Special Nut" Advantage: Includes high-grade Stainless Steel all-metal prevailing torque lock nuts. These are mandatory for high-vibration large-bore systems; they won't melt or back off like cheap nylon-insert alternatives.
- Gasket-Less Seal: Precision-machined to eliminate the need for traditional, leak-prone flange gaskets under boost.
Installation Pro-Tips:
- Anti-Seize is Mandatory: Use it on all threads to prevent stainless steel galling (seizing) after heat cycles.
- Tap-to-Seat: Use a rubber mallet to gently tap the clamp perimeter while tightening to ensure a uniform 360-degree seal.
- Alignment First: Ensure your large-bore piping is square and naturally aligned before tightening—don't use the clamp to force alignment.
