We operate in these
SFC KOENIG solutions are used wherever safe, reliable sealing and flow control is mission-critical. KOENIG EXPANDER®, KOENIG RESTRICTOR®, and KOENIG CHECK VALVE® components are found across four core markets — Electronics & Semiconductor, Aerospace & Defense, Mobility, and Medical & Life Science — and three emerging frontiers where precision sealing and flow control needs are growing fastest: Industrial Machinery, Energy, and Emerging Technology.
With around 100 years of experience, more than 5 billion pieces installed, and field failure rates below 1 PPM, SFC KOENIG is the trusted partner wherever performance, safety, and reliability cannot be compromised.
Flight-critical and defense systems demand lightweight, high-integrity sealing and flow control. SFC KOENIG expander plugs, restrictors, and check valves are engineered to meet the strictest safety and qualification standards.
Mobility platforms face tighter packaging and higher performance demands. KOENIG components seal access bores and control fluid flow directly, supporting the safety, durability, and efficiency targets of modern systems.
Industrial equipment requires continuous operation without costly unplanned downtime. KOENIG components deliver precise flow control, backflow protection, and reliable sealing in demanding high-duty-cycle pneumatic and hydraulic environments and circuits.
Power generation infrastructure operates under continuous load and high pressure. SFC KOENIG components are engineered directly into turbines and transformers to deliver leak-tight sealing and precise flow control effectively.
Emerging platforms require reliable flow control in compact designs. SFC KOENIG partners with innovators to apply custom engineering solutions, ensuring new technologies meet strict safety, reliability, and performance targets.
Semiconductor and data center systems demand tight tolerances to prevent downtime. KOENIG components provide tamper-resistant sealing and precise flow control to maintain critical advanced manufacturing and infrastructure uptime securely.
Medical devices require quiet and reliable operation for patient safety. SFC KOENIG high-precision components provide leak-tight sealing and controlled fluid flow to protect the integrity of laboratory diagnostic systems.
