Granatelli 4" Mating Flat V-Band Flange - 308540

GRANATELLI EXHAUST FABRICATION HARDWARE

4-INCH EXHAUST SYSTEMS DESERVE A STRONG, SERVICEABLE V-BAND CONNECTION.

The Granatelli Motor Sports 308540 4.0" (102mm) Mating Flat Flange Kit provides a convenient connection solution for large-diameter exhaust, turbo, diesel, marine and custom fabrication applications.

This complete kit combines flat mating flanges with a V-band clamp, creating a removable connection that can make custom exhaust systems easier to assemble, service and modify.

Why Use a V-Band Connection?

V-band connections are an excellent choice when you want a secure yet removable exhaust connection. The clamp allows compatible flanges to be joined without relying on a traditional multi-bolt flange pattern, making future service or exhaust-system modifications easier.

FLAT MATING FLANGE DESIGN

Clean, Simple & Fabrication-Friendly

The flat mating flange design provides a straightforward connection surface for custom exhaust fabrication. Once properly welded to compatible tubing, the flanges can be secured together using the included V-band clamp for a clean and serviceable exhaust joint.

PRECISION FABRICATION COMPONENT

Built for Custom Exhaust & Performance Applications

Granatelli's V-band components are precision-machined for applications where reliable alignment and a serviceable connection are important. The 308540 provides a large-diameter 4-inch connection for builders working on high-flow exhaust and custom fabrication projects.
