High-performance vacuum flanges and fittings for UHV and HV systems, compatible with all major industry standards
Essex Bay Engineering offers one of the most comprehensive selections of vacuum flanges in the industry, supporting both high vacuum (HV) and ultrahigh vacuum (UHV) systems. Our product range includes all five industry-standard vacuum connection systems—ensuring compatibility, flexibility, and performance across a wide range of scientific, industrial, and research applications.
We provide Conflat® (CF) flanges(304ss), Conflat® (CF) flanges(316LN), ISO-KF (Kwik-Flange), ISO-LF (Large-Flange), ANSI-ASA flanges, and Quick Disconnect (QD) assemblies. Additionally, Essex Bay Engineering offers weld stub fittings and a vast selection of hybrid flange adapters, making it easy to transition between different flange types or mating systems. This adaptability ensures seamless integration in new builds or retrofits where dissimilar flange types must be connected reliably.
Essex Bay Engineering’s CF flanges are fully Conflat® compatible and feature a metal seal design suitable for demanding UHV environments, with proven performance down to 1×10⁻¹³ Torr. Available in sizes to accommodate tube diameters from 1/8 inch (3.2 mm) to 14 inches (356 mm), Essex Bay Engineering CF flanges are ideal for systems that require leak-tight, thermally resilient connections. For larger assemblies, wire seal flanges are offered to support tube sizes up to 24 inches (610 mm) in diameter.
Whether you’re building a compact research chamber or a large-scale vacuum infrastructure, Essex Bay Engineering’s broad vacuum flange portfolio ensures maximum flexibility and reliability for your vacuum system design.
