[Material]304 Stainless steel band, Zinc-Plated 7/16-14 bolt and nut, Steel gasket, Aluminum alloy I-block. [Advantage Ease of Installation]: This exhaust band clamp sleeve comes with fastening bolts. You only need to tighten or lose the bolts to connect or release. No welding required, easy to use. [Size]: Joins 2.75 "OD pipe to 2.75 "OD pipe, width of strap: 3.0 inch /76.7mm.Confirm the size before buying [Application]: Sealed exhaust clamps are maintenance components for silencers. Narrow band clamps can be used for catalytic converters, exhaust nozzles, exhaust manifolds, exhaust resonators, exhaust hoses, and exhaust muffler maintenance projects.system components such as pipes, mufflers, catalytic converters etc. [Features] These exhaust clamps adopt an integrated structure, minimizing the complexity of the number of parts and maximizing material efficiency, thereby reducing weight. 12.9 degree high-strength fasteners provide true sealing force, and the unique reaction block provides 360 °uniformly distributed tensile force, completing sealing around the connected exhaust components while preventing pipelined deformation. [Enhanced Sealing Performance]Our exhaust pipe clamps, paired with high-quality sealant, ensure a tight fit after installation, preventing gas leaks and improving the overall performance of the exhaust system.
