Description
Stainless Steel KF Vacuum Tee Fitting 1-1/4 Flange 3/4 Tube w/ Centering Rings
This stainless steel KF (ISO-KF) vacuum tee fitting provides a three-way T-junction for vacuum piping systems. It features KF-style quick-release flanges on all three ports, allowing fast tool-free assembly and disassembly with standard centering rings and clamps. Two KF centering rings with rubber O-rings are included.

Applications
KF (Klein Flange / ISO-KF) vacuum fittings are a widely used standard in low-to-medium vacuum systems, typically covering the rough to high vacuum range (atmospheric down to around 10⁻³ to 10⁻⁴ Torr). Tee fittings like this one are used to branch a vacuum line into two directions — for example, connecting a pump to two chambers, adding a gauge port, or routing gas lines within a vacuum system. They are common in semiconductor processing, thin-film deposition (PVD/CVD), research and laboratory vacuum setups, mass spectrometry, and industrial vacuum systems. The KF quick-flange system uses a centering ring with an O-ring seal seated between two flanges, held together by a lever-action or screw clamp, making connections fast and reconfigurable without special tooling. Stainless steel construction provides corrosion resistance and low outgassing, making it suitable for clean vacuum environments.
This stainless steel KF vacuum tee fitting has been inspected and is in good condition. The fitting body shows light surface marks consistent with prior use but no cracks, deformation, or damage to the flange seating surfaces. Two KF centering rings with O-rings are included and appear to be in usable condition. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
