Dual Wall Air Gap Manifolds

Flexible Metal's Hamburg, Michigan facility has been an industry leader in the development of formed manifolds, turbocharger housings and ducts incorporating dual wall air gap technology. With modern engines operating at high temperatures, formed manifolds offer substantial cost saving by limiting the use of high Nickel alloys to the inner liner with the added benefit of the low thermal inertia which reduces emissions. These designs are in service on high volume production vehicles, and development is continuing to expand the application of this technology.
