About Stainless Bros Transition Reducer

Stainless Bros transition reducers are fabrication pieces for moving cleanly between two tubing diameters without using an abrupt step. The reducer geometry helps create a smoother change in cross-sectional area for exhaust, intake, charge-pipe and custom fabrication work. The catalog includes stainless, specialty-alloy and selected aluminum transitions with different inlet/outlet diameters, lengths and wall specifications. Select the reducer by both end sizes, material, wall thickness and overall length so it can be integrated cleanly with the adjoining tubing.

Fabrication Note: Confirm material grade, tubing size, wall thickness, connection style and all listed dimensions before cutting or welding. Custom-fabrication components are generally not vehicle-specific unless an exact engine, turbocharger or sensor application is stated in the product details.
