MDC’s 13-1/4" Outer Diameter (336.55 mm) Conflat® (CF) flange, constructed from corrosion-resistant 304 stainless steel, is engineered for large-format ultrahigh vacuum (UHV) systems requiring high thermal stability, precision sealing, and mechanical strength. With a nominal designation of DN450CF, this flange delivers consistent performance for vacuum environments operating under extreme conditions.

Key Features

UHV Performance: Vacuum rated to 1x10⁻¹³ Torr (1.33×10⁻¹¹ Pa)
High Temperature Capability: Rated up to 450°C (842°F) for bake-out operations
Material: Precision-machined from 304 stainless steel for durability and corrosion resistance
Design Options: Available in rotatable and nonrotatable configurations
Gasket Compatibility: Supports OFE copper and optional FKM elastomer gaskets
Standard Interface: Fully Conflat® compatible with industry-standard CF systems
Bolt Hole Options:
Through-hole flanges: 30 holes drilled to 0.390" (9.91 mm)
Tapped flanges: 30 holes threaded to 0.375-24 UNF

Applications

MDC's 13.25" CF flange is a critical component in large-scale UHV systems found in semiconductor manufacturing, synchrotron beamlines, particle accelerators, thin-film deposition (PVD/CVD), surface science research, and aerospace simulation chambers. Its high sealing integrity, thermal resilience, and robust mechanical design make it suitable for use in national laboratories, fusion research facilities, and advanced vacuum chamber assemblies requiring precise, repeatable performance.
