MDC’s Nipple Reducer – Straight Tube is a precision-engineered vacuum component designed to connect two different-sized Conflat® (CF) flanges in ultra-high vacuum (UHV) systems. Constructed from corrosion-resistant 304 stainless steel, this straight-tube reducer allows seamless transitions between mismatched CF flange sizes without compromising vacuum integrity or structural alignment.

The smaller flange is rotatable, offering greater flexibility during installation by allowing proper bolt-hole orientation—especially beneficial in tight spaces or modular assemblies. Designed for demanding environments, this reducer supports vacuum levels down to 1×10⁻¹³ Torr (1.33×10⁻¹¹ Pa) and withstands high temperatures up to 450°C (842°F). Each unit features MDC’s standard matte surface finish, which minimizes outgassing and improves vacuum system performance.

Industry Applications

The MDC Nipple Reducer – Straight Tube is used across a wide range of industries that demand high vacuum integrity and precise component transitions. Common applications include semiconductor processing, photonics systems, aerospace vacuum chambers, surface analysis tools, mass spectrometry setups, and UHV beamline connections. It is particularly useful for integrating equipment with different CF flange sizes, adapting diagnostics ports, or customizing chamber configurations. With its UHV rating, rotatable flange, and high-temperature tolerance, it offers dependable performance in both research laboratories and industrial vacuum systems.
