Stainless Steel Eccentric Reducer 304
AISI 304 eccentric reducers provide an offset diameter transition with one flat side — typically for pump suction, drainage, or air-pocket avoidance on horizontal stainless lines. Quoted and sold per piece.

Applications & Selection Guide
Stainless steel eccentric reducers in AISI 304 to EN 10253 / ASME B16.9 — diameter transitions with one flat side, welded plain ends, pickled finish.
Installed flat-side-up on horizontal pump suction lines they prevent air pockets and cavitation; flat-side-down they keep a constant invert for drainable hygienic lines — a CIP design requirement in food and pharma piping. Choose the large × small OD pair from the table above and mark orientation on your drawings.
Quoted and sold per piece. Include both ODs, quantity, and delivery country in your quote request.
Listed sizes are 219.1 × 141.3 mm (DN200 × DN125) and 73 × 60.3 mm (2½" × 2"). The centre lines of the two ends are offset by half the difference of the outside diameters, about 39 mm for 219.1 × 141.3 and about 6 mm for 73 × 60.3, which is the step to allow for in the pipe support heights.
