The MDC Nipple Reducer – Conical is a space-efficient vacuum component engineered to join two Conflat® (CF) flanges of different sizes in ultra-high vacuum (UHV) systems. Unlike standard straight reducers, the conical geometry provides a compact and streamlined profile, ideal for systems where spatial constraints or alignment angles are a concern.

Constructed from high-purity 304 stainless steel, this reducer supports vacuum levels down to 1×10⁻¹³ Torr (1.33×10⁻¹¹ Pa) and withstands continuous bakeout temperatures up to 450°C (842°F). The smaller flange is rotatable, allowing for easier alignment of bolt holes and smoother installation. A standard matte finish helps reduce surface outgassing and enhances UHV performance, making it suitable for sensitive scientific and industrial vacuum environments.

Industry Applications:

MDC’s Nipple Reducer – Conical is ideal for ultra-high vacuum systems requiring compact, high-performance flange transitions. It is commonly used in semiconductor fabrication tools, beamline assemblies, surface science instruments, UHV chambers, and photonics and optoelectronic systems. The conical profile allows system designers to adapt between different CF flange sizes while optimizing layout space and maintaining alignment accuracy. With its UHV and high-temperature performance, this reducer is an essential component in both industrial and research environments where space-saving configurations are critical.
