The MDC Large-Flange™ ISO LF NW160 is a versatile, cost-effective stainless steel vacuum flange designed for use in high vacuum environments requiring frequent system assembly and disassembly. Constructed from Type 304 stainless steel, it offers both clamp-style and bolt-style configurations for seamless integration into a variety of vacuum setups:

Clamp Style Dimensions: 7.09" OD × 5.87" ID (180 mm × 149.1 mm)
Bolt Style Dimensions: 8.86" OD × 5.83" ID (225 mm × 148.1 mm)

This flange system is vacuum rated to 1x10⁻⁸ Torr (1.33×10⁻⁶ Pa) and bakeable to 150°C, making it ideal for demanding scientific, industrial, and research-grade vacuum applications. Fully compliant with ISO LF standards, the NW160 flange is also compatible with most third-party ISO LF components. Available in blanked versions, it supports custom machining or sealing off unused vacuum ports.

Industry Applications

The Large-Flange™ ISO LF NW160 flange is widely used across industries that demand reliable high vacuum sealing and modular assembly, such as semiconductor processing, space simulation, thin-film coating, vacuum metallurgy, and large-scale research facilities. Its high conductance, robust geometry, and standardized design make it ideal for vacuum chambers, pumping systems, and analytical equipment. Whether used in a custom-built lab or a commercial cleanroom, the NW160 flange delivers flexibility, durability, and performance that meet the evolving needs of today’s high-vacuum technologies.
