MDC’s Kwik-Flange™ ISO KF and Large-Flange™ ISO LF Five-Way Crosses are high-performance modular building-block components designed for complex, multi-directional vacuum system configurations. Engineered from Type 304 stainless steel using drawn and welded vacuum tubing, these fittings offer exceptional structural strength, corrosion resistance, and leak-tight performance. Their symmetric, nonrotatable geometry ensures ease of installation and reliable alignment across multiple connection points. Available in flange sizes NW16 through NW500 (DN16–DN500), MDC five-way crosses are ideal for creating centralized vacuum hubs, test setups, and branching configurations in high or ultra-high vacuum applications.

Industry Applications

MDC’s Five-Way Crosses are built for semiconductor, pharmaceutical, aerospace, and scientific research applications that require modular, multi-port vacuum connectivity. These fittings enable the integration of several vacuum lines from a single hub, optimizing space and enhancing control in complex systems. Ideal for vacuum chambers, cleanroom assemblies, and UHV instrumentation setups, the five-way cross supports ISO KF and LF compatibility for seamless system expansion. Its robust construction and leak-tight performance ensure reliability in high and ultra-high vacuum environments, supporting long-term operation and system adaptability across mission-critical industrial and research platforms.
