MDC’s Reducing Crosses are engineered for vacuum system layouts requiring CF-to-CF connections of different sizes in a four-way configuration. Each cross is fabricated from 304 stainless steel drawn and welded vacuum tubing, providing exceptional durability, corrosion resistance, and structural integrity under demanding conditions. Each of the four ports features a rotatable CF flange, allowing for precise alignment and modular flexibility during system integration.

These crosses are UHV-rated to 1x10⁻¹³ Torr and can operate at temperatures up to 450°C (842°F), making them suitable for high-performance vacuum systems. The standard matte finish helps minimize outgassing and ensures surface cleanliness. Body style is tube-size dependent to maintain strength and vacuum performance across size ranges.

Industry Applications

MDC’s Reducing Crosses are used in a wide range of ultra-high vacuum (UHV) applications that require multi-directional routing between flanges of varying sizes. These fittings are ideal for semiconductor manufacturing, thin film deposition, beamline systems, and surface science research, where system flexibility and vacuum integrity are essential. Their rotatable flanges simplify installation and allow quick integration of ports for gauges, sensors, or pumps. They are also used in fusion research, space simulation, and vacuum metrology, delivering reliable, high-temperature, and leak-tight performance for both experimental and production environments.
