Conical reducers for vacuum system are precision-engineered transition fittings designed to connect vacuum components of different diameters while maintaining optimal gas flow conductance. Unlike standard pipe reducers, these vacuum-rated conical reducers feature a smooth, continuous taper that minimizes outgassing, reduces virtual leaks, and preserves the integrity of high and ultra-high vacuum environments (10⁻³ to 10⁻⁹ Torr).
Manufactured from vacuum-compatible materials such as 304L and 316L stainless steel, these components are critical for vacuum chambers, turbo-molecular pump inlets, foreline tubing, and load lock systems. Each conical reducer is fabricated with strict attention to internal surface finish, weld quality, and leak integrity. Whether you are building a thin-film deposition system, a helium leak detection station, or a research vacuum manifold, these reducers deliver the conductance and reliability that high-vacuum applications demand.
Geometry: True concentric conical taper for smooth flow transition
Vacuum Range: Atmospheric to 1×10⁻⁹ Torr (UHV compatible)
Flange Standards: ISO-KF, ISO-K, CF (ConFlat), or custom
Material: 304L / 316L stainless steel (low magnetic permeability)
Internal Surface Finish: Ra ≤ 0.8 µm (electropolished or mechanically polished)
Outgassing Rate: < 2×10⁻⁸ Torr·L/s·cm² (after vacuum cleaning)
Leak Integrity: Helium leak tested to < 1×10⁻⁹ mbar·L/s
Bakeout Capability: Up to 400°C (CF flanges, metal seals)
Size Transition: Custom diameter ratios (e.g., DN40 to DN16, DN100 to DN63)
Thin-film deposition: Sputtering and evaporation systems
Helium leak detection: Adapter between detector port and test object
R&D vacuum manifolds: Transitioning between different DN sizes
Semiconductor equipment: Load lock and transfer chambers
Surface analysis: UHV systems for XPS, AES, or STM
Space simulation chambers: Thermal vacuum system plumbing
We combine CNC machining, orbital welding, and electropolishing to deliver vacuum fittings that meet or exceed ASTM E2737 standards. Every conical reducer is individually helium leak tested, cleaned in an ultrasonic bath with semiconductor-grade detergents, and double-bagged in a cleanroom. Custom transitions, non-standard lengths, and special flange orientations are available with engineering support.
