Borla Universal 3-Inch T-304 Stainless Steel AccuSeal Single Bolt Band Clamp (18330)
Secure your high-performance custom exhaust system with the high-impact Borla Universal AccuSeal Single Bolt Band Clamp. Custom-engineered to fit over standard 3-inch outer diameter exhaust pipelines, this premium installation accessory introduces an industrial-grade sealing asset unique to the industry: a specialized 360-degree reaction block system. Formulated explicitly for driving enthusiasts, custom fabricators, and professional builders who demand an absolute leak-free union without crushing the underlying tubing, this band clamp distributes intense tension uniformly. By transitioning clamping force evenly around the entire circumference of the metal slip joint, this premium band prevents pipe distortion or exhaust gas blowouts while maintaining clean structural alignment along your under-chassis routing.
The internal engineering of the Borla 18330 targets key structural connection issues by incorporating an upgraded high-efficiency single-bolt layout. Purpose-built for critical slip-joint connections where you are coupling an outer diameter (OD) tube directly into an inner diameter (ID) pipe expansion or muffler neck, this high-strength clamp features a stout 1.25-inch wide strap. At its core, the heavy-duty band stretches to exert radial pressure that seals much more effectively than a traditional U-bolt or saddle clamp, making it perfect for high-vibration street or track conditions. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable hardware component defends permanently against structural degradation, stretching, and intense under-car heat. Precision manufactured for a smooth take-up action, this universal hardware piece delivers an elite solution that allows your entire exhaust assembly to be easily disassembled for rapid chassis maintenance, transmission service, or component cleaning.
Natural Mill Finish Styling: This premium fabrication hardware accessory features a raw, industrial natural mill finish directly out of the box. For show car builds or exposed chassis areas where aesthetic coordination is crucial, the high-grade T-304 stainless steel material can easily be custom brushed or high-gloss mirror polished prior to final deployment to match your premium exhaust system components cleanly.
Fabrication Installation Guideline Note: This AccuSeal band clamp is a completely bolt-on assembly requiring no welding. Safe and successful installation requires sliding the 1.25-inch wide band over a slotted slip-fit connection before performing final torque adjustments with standard hand tools.
Features
- Complete AccuSeal Single-Bolt Assembly: Advanced reaction block and high-strength fastener design provides a comprehensive 360-degree radial seal
