MDC’s Conical Reducers – Weldable Components serve as precision transition elements within custom vacuum plumbing assemblies, enabling smooth reduction between dissimilar tube diameters. Fabricated from Type 304 stainless steel, these components are welded and mandrel-drawn, ensuring structural consistency and UHV compatibility. Reducers are provided in vacuum-sealed, shrink-wrapped packaging, preserving interior surface cleanliness. Each reducer is saw cut and deburred, and intended for integration by welding, brazing, or soldering. Available in main tube O.D. sizes from 1" to 6" (25.4 mm to 152.4 mm), these fittings are ideal for custom system construction. Special finishes, machined lengths, and polishing options are available upon request.

Industry Applications

MDC’s weldable conical reducers are engineered for precise size transitions in ultra-high vacuum systems, commonly found in semiconductor fabrication, photonics, aerospace, and plasma physics laboratories. These reducers support vacuum chamber designs and complex assemblies where dimensional adaptation and leak-tight performance are critical. Their high-temperature and UHV ratings make them ideal for thermal cycling, bakeout processes, and UHV-compatible instrumentation. With full integration support for Conflat®, ISO, and ASA systems, these fittings streamline custom vacuum pipelines across R&D, manufacturing, and analytical platforms requiring optimal cleanliness and weldable adaptability.
