Borla Performance 4-Inch AccuSeal Stainless Steel Single Bolt Band Clamp (18340)
Secure large-diameter exhaust plumbing and eliminate leaks without crushing your tubing with the Borla Performance 4-Inch AccuSeal Single Bolt Band Clamp. Engineered as a premium, high-strength joining solution for heavy-duty trucks, diesel applications, and high-horsepower custom builds, this advanced clamp is designed specifically for overlapping slip-joint connections. It seamlessly secures outside diameter (O.D.) piping into inside diameter (I.D.) pipes or high-flow muffler inlets. By distributing clamping force evenly across a wide surface area, the AccuSeal design delivers a full 360 degrees of uniform sealing pressure to eliminate gas leaks while preventing irreversible tube crimping or distortion.
Built to handle extreme underbody thermal expansion, massive diesel exhaust temperatures, and intense road vibrations, this high-performance hardware component is manufactured entirely from top-tier T-304 austenitic stainless steel to provide lifelong defense against rust, oxidation, and structural pitting. The sleek 1.25-inch wide band features a low-profile, single-bolt fastening layout that simplifies installation in tight under-chassis spaces. This service-friendly configuration allows your large-bore exhaust sections to be easily disassembled and reassembled for maintenance, upgrades, or track tuning. Arriving in a natural mill finish, the band can be brushed or polished prior to final installation. This heavy-duty 4-inch clamp is proudly engineered by Borla to bring professional-grade structural integrity to your high-performance exhaust layout.
