Product Description
The Metraflex model EX Joint is a bellows expansion joint tailor made for diesel exhaust applications. The standard EX Joint allows for 3” of compression; custom designs are available. Available in either weld or flanged ends. Floating flanges are also available.
Metraflex can provide manifold joints that are typically located between the generator manifold and silencer, and we can provide mating flanges to match the most common generator sets.
All in-line bellows expansion joints develop anchor loads and require guiding. Refer to the design guide or consult Metraflex or your local representative for more information.
Available in both import and domestic models.
Product Highlights
