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.

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.
