4.0 Inch Stainless Steel V-Band Flange Assembly with Clamp

Stop hunting for loose parts. This complete assembly gives you everything you need to make a clean, leak-free connection the first time.

Features & Benefits

Everything Included, Ready to Weld

The kit comes with two matched flanges and the V-band clamp, so you're not sourcing hardware from three different places. Grab it, prep your pipe, and get building.

4.0" Nominal Diameter

Sized accurately at 4.0 inches to suit a wide range of turbo outlet, exhaust, and charge-air piping applications. Whether you're fabbing a custom exhaust section, connecting a large-frame turbocharger, or replacing worn hardware on an existing build, the fitment is consistent and reliable.

Stainless Steel Construction

Built from stainless steel for genuine corrosion resistance, a real advantage when your build is exposed to road salt, moisture, and the freeze-thaw cycles that come with North American winters. The material holds up under heat cycling and keeps its integrity over the long haul.

Universal Fitment for Any Turbo Build

This is a universal BSI Inc. component, equally at home on gas or diesel builds, street cars, trucks, or race fabrication. Turbo exhaust connections, downpipes, intercooler piping, wastegate outlets: if it's 4.0" and needs a secure, serviceable joint, this assembly handles it.

Quick-Release Serviceability

V-band connections make future disassembly straightforward. No fighting with rusted bolts when it's time to pull the turbo or modify the layout. Loosen the clamp and the joint comes apart cleanly.

Ships from Canada

Sourced directly through Black Sheep Industries, so Canadian customers skip the brokerage fees and extended wait times that come with cross-border orders. U.S. customers get a quality North American-supplied part shipped efficiently to their door.

Whether you're finishing a fresh turbo build or replacing a worn connection point, this 4.0 inch stainless steel v-band flange assembly is the straightforward, durable solution that gets the job done right.
