Ottawa Narrow Band Exhaust Clamps (Slip Fit Connections)
Ottawa Narrow Band Exhaust Clamps are a simple, effective, way to connect exhaust system components such as mufflers, resonators, and tips. They provide a unique seal with high clamping loads without permanently distorting your exhaust components, allowing the flexibility to disassemble for service in the future.
Narrow Band clamps are available in all of the standard industry sizes ranging from 1-3/4" (44.5mm) through 6" (152.4mm) in either 430 stainless steel or aluminized steel. These clamps feature unitized construction which minimizes part number complexity and maximizes material efficiency for reduced weight and lower costs.
Narrow Band Clamps are designed to be used on ID/OD style connections. For example, if you have a 2.5" exhaust, the clamp is designed to fit over tubing that has been flared to a 2.50" ID, or over an exhaust component such as a muffler that has a 2.5" ID inlet or outlet. For optimal sealing, the larger side of the connection (the ID side) should have relief slots cut in it.
