Triad specializes in multi-ply metal exhaust bellows which provides the best cycle life available. We stock special flanges to mate with most major engine manufacturers exhaust manifolds and turbo chargers. Floating flanges are standard for Caterpillar, Cummins and Detroit / MTU and Waukesha exhaust expansion joints. For high flow velocities Flow liners are recommended. All expansion joints can be manufactured to any length that best suits the available space. Any weldable fitting can be attached to the outlet side of the bellows to make the installation quick and easy. Manufacturing custom expansion joints is our business, let us know how we can help.
