This 3-1/2" Stainless Works single band clamp provides a tidy stainless connection for larger exhaust tubing where moderate clamping is sufficient. Install by tightening with a 1/4" ratchet and slotting the overlapping pipe to allow compression. If your setup requires stronger clamping under load, Stainless Works suggests using their Accuseal or saddle clamps.
