Our 3-inch Exhaust Band Clamp Assemblies utilize a 304 stainless-steel exhaust band clamp and 3-inch mild steel v-band flange. Our "Male/Female" flanges have an interlocking seating surface to ensure proper alignment during installation. The butt-weld side of the flanges offer a small groove that allows the flange and tube to be aligned better prior to welding. Each assembly includes one (1) t-bolt style clamp and two (2) interlocking flanges.

Please note: Our V-Band clamps are supplied with a metal lock nut and a non-locking hex nut. The metal lock nut is a locking-style nut and is not intended to be used during mock-up. Attempting to thread, remove, and re-thread the lock nut may cause damage to the "T-Bolt" section of the clamp. In some cases, excessive force can damage and/or break the "T-Bolt" section of the clamp. If you intend to use our clamps during the mock-up process please use a non-locking hex nut.
Ace Race Parts is not responsible for damage caused to our clamps due to the use of the locking-style nut during mock-up or removal. The thread pitch of our hex nuts, lock nuts and the threaded portion of the "T-Bolt" section of the clamp is 8mm-1.5 (fine thread).
Note: The photo of the three types of nuts includes a nylon lock nut. This type of nut is not always supplied with our v-bands. The two main types of nuts supplied with each v-band assembly or clamp is the metal non-locking hex nut (finish hex nut) and the metal lock nut. If you would like a nylon lock nut to be supplied with your order please contact us.
