About Us

KVT-Koenig LLC is the company created by the
recent merger of Farmington Engineering and Sherex Industries. These companies
had been the top US suppliers of sealing plugs and flow control devices
for more than 30 years, and are now combined under the Swiss-based KVT group.

solutions.

Our Koenig Expander sealing plugs, CV Expander sealing plugs, threaded

holes in a manifold or control flow, we have products that can help you
get the most out of your application.

Based in Madison, CT, KVT-Koenig LLC is certified to the TS 16949:2002
