Today, Sealcon is still family owned and operated by Daniel Spühler, and is the leading supplier of Hummel strain relief fittings and connectors. We also work with Hi-Tech Controls to sell cable from the German manufacturer Helukabel. With over 6000 products, we offer a variety of configurations and make it easy for you to find the right part for your application. Our inventory is replenished weekly so we can respond to changing demands! Purchase orders received before noon MST are often shipped the same day.
