Koenig Expander

SFC Koenig hole sealing and flow control components ensure complete integrity when managing fluid and gas systems. With over 5 billion installations worldwide, the Koenig Expander ensures field failure rates below 1 PPM.

Design Engineers rely on the Koenig Expander for effective hole sealing in demanding conditions, while operations and production line operators specify the Koenig range for ease of installation, zero waste and low integration costs.

Leveraging unique expansion technology, both hole sealing plugs and flow control solutions ensure leak-free performance, facilitating precise flow regulation by preventing side leakage. The metal-to-metal expansion principle uses a one-piece mechanical design, preventing FOD, solvent use and pre-machining or finishing.
