This v-band clamp fits on flanges that go on 3-1/2" exhaust systems. Stainless steel.
Note: There are many sizes and types of V-band clamps. This is the "standard" clamp for the exhaust pipe-to-turbocharger connection on many vehicles.
However, it may not fit your vehicle.
Please contact us with your application information and dimensions so we can send you the correct clamp.
If you are trying to connect two flanges together, you need special double-rolled flat-faced flanges and the matching V-Band clamp. That assembly is called a "stack breaker" and can be seen on the Exhaust Flanges page.
