The Stainless Bros 4.0in V-band assembly ships as two 304 stainless steel flanges plus one clamp to form a complete 4.0" V-band joint. Supplied as a matched set, it’s intended for turbo and exhaust plumbing where a clamped, removable stainless V-band connection is preferable for modular builds or ease of service.
