MDC’s Kwik-Flange™ ISO KF and Large-Flange™ ISO LF Four-Way Crosses are highly adaptable modular building-block components designed to enable multi-directional connections within high vacuum systems. Fabricated from Type 304 stainless steel with drawn and welded vacuum tubing, these crosses offer exceptional corrosion resistance, structural strength, and leak-tight performance. The symmetric, nonrotatable geometry allows for consistent alignment and simplified system integration. Available in flange sizes from NW16 to NW500 (DN16–DN500), and with body types tailored to tube dimensions, these fittings are built to perform across a wide range of vacuum configurations.

Industry Applications

MDC’s Four-Way Crosses are widely used in semiconductor processing, pharmaceutical manufacturing, aerospace vacuum systems, and research laboratories requiring multi-branch vacuum connectivity. Their ISO KF and LF compatibility supports seamless integration into complex system layouts, allowing four vacuum lines to converge at a single point. These crosses are ideal for UHV chambers, analytical equipment, and modular assemblies that demand leak-tight, space-efficient configurations. With sizes from NW16 to NW500, MDC crosses offer flexibility for systems both large and small, delivering robust performance under demanding environmental and operational conditions.
