MDC’s Four-Way Crosses provide a precise, high-performance solution for complex ultra-high vacuum (UHV) system layouts requiring multi-directional CF flange connections. These cross fittings are manufactured from 304 stainless steel drawn and welded vacuum tubing, delivering exceptional mechanical strength, corrosion resistance, and long-term durability. Each of the four axes features a rotatable CF flange, ensuring flexible orientation and simplified system alignment during installation.

Designed for UHV service down to 1x10⁻¹³ Torr and temperature rated up to 450°C (842°F), these components are ideal for high-temperature and high-vacuum applications. The standard matte finish minimizes outgassing and improves surface cleanliness. Depending on tube size, the body style may vary to ensure optimized performance.

Industry Applications

MDC’s Four-Way Crosses are vital in advanced UHV systems that require precise, leak-tight connections in multiple directions. Commonly used in semiconductor processing equipment, surface science instrumentation, and beamline transport systems, these fittings allow modular expansion and integration of diagnostic ports, gauges, and pumps. They are also suitable for fusion research, space simulation chambers, and high-vacuum analytical tools like mass spectrometers and electron microscopes. With rotatable flanges and support for CF flange sizes of varying diameters, MDC’s Four-Way Crosses enable efficient system routing, alignment flexibility, and reliable performance in high-precision vacuum environments.
