The RF 63mm–51mm Stainless Steel Reducer is a concentric transition fitting pressed from 201 stainless steel, letting you step cleanly between 63mm and 51mm tubing in a single weld. The pressed shape maintains smooth internal flow and eliminates the need for hand-formed transitions or stepped lap joints.
201 grade stainless offers excellent corrosion resistance and high-temperature performance for demanding automotive applications, at a more accessible price point than 304.
