MDC’s Kwik-Flange™ ISO KF and Large-Flange™ ISO LF Reducing Crosses are precision-engineered modular vacuum components that enable multi-directional branching with flange size transitions. Constructed from Type 304 stainless steel using drawn and welded vacuum tubing, these crosses offer robust vacuum integrity, corrosion resistance, and structural stability. The symmetric, nonrotatable geometry allows for simple, accurate alignment and efficient system assembly. Designed to connect different flange sizes at intersecting ports, MDC reducing crosses are available in main flange sizes NW25 to NW160 (DN25–DN160), supporting flexibility in complex or compact vacuum networks.

Industry Applications

MDC’s Reducing Crosses are essential for semiconductor, pharmaceutical, aerospace, and research vacuum systems that require multi-branch configurations with size variation. These fittings enable the transition between differing flange diameters, optimizing space and flow control within compact systems. Commonly used in vacuum chambers, cleanroom process tools, and analytical setups, they support high performance under stringent conditions. Their ISO KF and LF compatibility ensures easy integration into both new and legacy vacuum infrastructures. The durable stainless steel design and leak-tight reliability make them a trusted choice for long-term use in high and ultra-high vacuum applications.
