Collar band with V-band section with internal rings exactly 89-90 mm
The 2 included are made of stainless steel and guarantee a perfect coupling, as they are built with a male-female coupling and not female-female as it is easy to find on the market, so there is no gasket to be inserted as it guarantees a total seal.
Used on turbochargers at the exhaust gas outlet, or on exhaust systems and mufflers, or for other applications that use flanges of this type.
Applicable also up to 1000 degrees (temperature referred to the gas inside the muffler, clearly not on the clamp).
The technology of fixing with v-band clamps allows a much faster disassembly and reassembly and for this reason called "prontocorsa" (only one bolt to remove the turbocharger flange instead of the usual four bolts). It also allows not to have a gasket that can yield to heat as it ages and also requires less space than traditional flanges.
