MDC’s Male NPT to Kwik-Flange™ KF Hybrid Adapters provide a reliable transition between threaded NPT connections and ISO KF flange vacuum systems. These hybrid adapters are ideal for integrating vacuum components into systems that use pipe thread interfaces for instrumentation or process gas connections.

Each adapter is precision fabricated from 300 series stainless steel for durability and corrosion resistance. The male NPT connection allows for straightforward installation with piping systems using standard Teflon® thread sealant. The KF flange provides a quick-connect interface, compatible with ISO 2861 standard vacuum hardware.

Rated for high vacuum applications up to 1x10⁻⁸ Torr (1.33x10⁻⁶ Pa), these adapters are bakeable to 200°C and available in various thread and flange sizes to meet your specific application needs.

Industry Applications

MDC’s Male NPT to Kwik-Flange™ KF adapters are widely used in vacuum instrumentation, analytical equipment, R&D labs, and semiconductor tools. These adapters support smooth integration of gas delivery systems, gauge connections, and process interfaces between threaded pipe and KF-flanged vacuum assemblies in HV systems.
