MDC’s Multiport Angled fittings are engineered for advanced ultra-high vacuum (UHV) systems requiring multi-directional component access within compact setups. These precision fittings feature a central 2-3/4" ConFlat® (DN40CF / 70 mm OD) flange surrounded by six equally spaced angled mini CF flanges (1-1/3", DN16CF / 34 mm OD). Each mini flange includes a clearance hole and is strategically angled to support optimal alignment for feedthroughs, viewports, and sensors. Fabricated from 304 stainless steel drawn and welded vacuum tubing and fully electropolished, these components deliver superior vacuum compatibility with leak-tight performance rated to 1x10⁻¹³ Torr and thermal resistance up to 450°C (842°F). Ideal for tight UHV chamber integration, they provide flexibility, precision, and long-term cleanliness in research, manufacturing, and instrumentation environments.

Industry Applications

MDC’s Multiport Angled fittings are ideal for use in compact UHV systems across semiconductor fabrication, surface science, synchrotron beamlines, material research, and analytical instrumentation. The angled design supports efficient layout of diagnostic tools, manipulators, and viewports while minimizing space usage and interference. Their electropolished finish makes them suitable for cleanroom environments and applications where low particle generation and chemical resistance are critical. These fittings are frequently used in high-vacuum assemblies where multiple access points and precision alignment are required for optical paths, electrical feedthroughs, and vacuum measurement devices.
