The MDC Large-Flange™ ISO LF NW100 is a durable, reusable vacuum flange system built from Type 304 stainless steel for compatibility with high-performance vacuum environments. Designed for systems requiring fast, repeatable access, this NW100 flange supports both clamp-style and bolt-style configurations to accommodate a variety of assembly needs:

Clamp Style Dimensions: 5.12" OD × 3.83" ID (130 mm × 97.3 mm)
Bolt Style Dimensions: 6.50" OD × 3.87" ID (165 mm × 98.3 mm)

This component is vacuum rated to 1x10⁻⁸ Torr (1.33×10⁻⁶ Pa) and bakeable to 150°C, offering superior performance in clean, high-vacuum applications. Fully compliant with ISO LF specifications, NW100 flanges integrate seamlessly with most third-party ISO LF systems and are available in blanked formats for custom machining or sealing off unused ports.

Industry Applications

The Large-Flange™ ISO LF NW100 is widely used in vacuum chambers, high-energy physics systems, semiconductor fabrication tools, and analytical instrumentation. Ideal for environments that demand high vacuum sealing, system modularity, and frequent maintenance, the NW100 flange ensures efficient performance in R&D labs, industrial cleanrooms, and thin-film deposition equipment. Its ISO-compliant interface, large diameter, and reusability make it a preferred solution for building scalable and high-throughput vacuum systems.
