Stainless Works NBC350 3-1/2" Accuseal High-Torque Exhaust Band Clamp

The Stainless Works NBC350 is a 3-1/2" inner diameter Accuseal high-torque band clamp engineered for secure, leak-free exhaust connections. Built with a 16-gauge, 300 series stainless steel strap and a 1.25" band width, this clamp delivers superior clamping force while maintaining the round integrity of your exhaust tubing — a critical advantage over standard saddle-style clamps that can distort and oval the pipe under load.

Key Features:

• 3.500" Inner Diameter — designed for 3-1/2" exhaust tubing
• 16-Gauge 300 Series Stainless Steel Strap — corrosion-resistant and built to withstand high-heat exhaust environments
• 1.25" Band Width — broad clamping surface for a uniform, even seal
• Zinc-Plated 3/8" T-Bolt and Reaction Block Included — hardware included for easy installation
• High-Torque Design — maintains a tight, secure connection without deforming the tubing
• Will Not Oval the Tubing — superior geometry versus standard saddle clamps
• Universal Fitment — compatible with any 3-1/2" OD exhaust pipe or tubing

Sold individually, the Stainless Works NBC350 Accuseal band clamp is a trusted choice for performance exhaust builders, fabricators, and enthusiasts demanding a professional-grade connection in headers, exhaust systems, and custom tubing applications.
