In April 2014, KVT-Koenig became SFC KOENIG. This is the result of the sale of our Fastening Division to the Bossard Group in October 2012. Our name and logo are different, but our focus and commitment to provide the highest quality engineered solutions for sealing and flow control remains unchanged. The SFC KOENIG name and our well-known product brands, KOENIG EXPANDER and KOENIG RESTRICTOR, support our mission to be the Leader in Sealing and Flow Control Technology.

SFC KOENIG carries with it the over 85 year history of KVT-Koenig: Original inventor of the one-piece, metal-to-metal sealing solution over 40 years ago. ISO/TS 16949, ISO 9001 & ISO 14001 Certified. Over 3 billion installations. 0.5 PPM.
