| Stainless steel band clamps are mainly used for connecting and sealing between exhaust pipes, flex pipes, mufflers and catalytic sections. The function is to let two pipes hold together firmly without welding and without pressing the pipe out of shape, which makes it suitable for jobs that need repeated removal or easy service. Passenger cars, pickup trucks, commercial vehicles and some equipment use this type widely, and repair shops and exhaust fabrication also use it often, especially when the space is tight or welding is not preferred. | |||||||||
YDCT O type exhaust band clamp is made by stainless steel band, bolt, nut and reaction block. The band material can be SS304, SS409 or carbon steel, and the bolt, nut and spacer are carbon steel. The normal size range is from 1 3/4” to 7”, with standard band width 1.25 inch (about 32mm) and thickness 1.8mm. The band arc is formed by fixed tooling to keep even pressure on the overlap joint and give stable sealing performance.
The I-shape reaction block (inner spacer) helps spread the force during tightening and avoids the bolt pressing directly on the band, so the clamp can keep its shape under higher torque. Bolt grade can be 8.8 or 10.9, and the nuts are made according to DTF anti-loose standard. Normally it is not necessary to add lockpatch, but we can add it if the project requires.
