TRU-PURE™ Concentric Reducer Weld Ends (Type B)

The Concentric Reducer Weld Ends Type B is a high-purity fitting designed to connect different pipe sizes while slightly offsetting the weld bead to accommodate specific orbital welding requirements.

Unlike Type A, Type B features a counterbore on the larger end to match the wall thickness of the smaller tube, enabling smoother, more controlled weld transitions.

It is ideal for systems requiring precise alignment during automated welding processes. Compliant with ASME BPE standards and available in SF1 and SF4 surface finishes, this reducer offers excellent cleanability, reduced turbulence, and hygienic performance—making it well-suited for critical bioprocessing and pharmaceutical applications.
