Description
Waukesha Fluid Handling Stainless Steel KF Reducer Pipe Fitting 3.25 OD
This is a stainless steel KF conical reducer pipe fitting manufactured by Waukesha Fluid Handling. It transitions between two different KF flange sizes using a tapered conical body, with matching ID dimensions at both ends to maintain flow continuity. Both ends are finished with KF-style clamp flanges for tool-free connection to standard KF vacuum or fluid lines.

Applications
KF (Klein Flansch) fittings are a widely used standard in vacuum systems, laboratory plumbing, and light-duty fluid handling applications. Reducer fittings like this one are used wherever a vacuum or gas line needs to step down between two different tube or port sizes while maintaining a sealed connection. They are common in vacuum chambers, roughing and foreline pump connections, freeze-dryers, mass spectrometry systems, and general laboratory gas distribution. Waukesha Fluid Handling is a well-established American manufacturer of sanitary and industrial fluid handling components, and stainless steel construction makes these fittings appropriate for corrosive, high-purity, or clean-room-adjacent environments. This style of fitting is still in active use across semiconductor fabrication, analytical instrumentation, and university/research laboratory settings.
This Waukesha Fluid Handling stainless steel KF reducer pipe fitting is in good used condition. The fitting shows light surface marks and minor machining scuffs on the conical body, consistent with normal handling and use — no cracks, deformation, or damage to the KF clamp flanges at either end. The bore and seating surfaces appear clean and intact. Please view our photo set and contact us if you have any questions.
