Mishimoto V-Band Clamps are some of the strongest and most reliable clamps on the market. Tailored especially for the fabricator, this 3" (76.2mm ) aluminum V-band clamp provides a rigid and secure connection between intake and intercooler pipes. The V-band design makes assembly and disassembly a breeze and the included fabrication nut makes mock-up easy. Simply assemble the V-band clamp with the reusable nut, tack weld your pipes in place, and disassemble for final welding. Once you?re done welding, assemble the clamp with the provided locking nut and never worry about loosening. The included O-ring and strong 360-degree clamp ensure leak free running under even the highest pressure. Like all our clamps, this 3" (76.2mm ) aluminum V-band clamp is back by our Mishimoto Lifetime Warranty.
