ASME B16.9 stainless steel concentric reducer

Concentric Reducer

Following the ASME B16.9 standard, the concentric reducer is ideal for vertical piping applications, as it facilitates a uniform size reduction at a constant rate over a specified length.

ASME B16.9 stainless steel eccentric reducer

Eccentric Reducer

Following ASME B16.9, the eccentric reducer features an offset between the centerlines of the larger and smaller ends, creating a flat side that can be positioned either on top or bottom.
