Mide's Stern Tube Seals can also incorporate its HyroActive technology as a backup seal that automatically engages in situations where the main seal may be compromised - allowing the ship to continue to operate and return to a location where repairs can be performed. Many high-performance mechanical face seals use silicon carbide (SiC) or other hard face seal materials which are difficult to work with and brittle.  Midé’s seals use innovative durable materials with ultra-low friction leading to superior wear properties, long life and thus reduced total ownership cost (TOC)….even in the harshest environments.  Blue water or brown water Midé’s shaft seals will perform.   | ![pdf-icon](https://www.mide.com/hs-fs/hubfs/pdf-icon.png?width=206&name=pdf-icon.png) | ## Contact Our Sales Engineers for More Information and Pricing | | --- | --- | ![water-cooled-stern-tube-seal](https://www.mide.com/hs-fs/hubfs/Website%20Images/Water%20Lubricated%20Stern%20Tube%20Shaft%20Seals/water-cooled-stern-tube-seal.jpg?width=1170&name=water-cooled-stern-tube-seal.jpg)   [![Contact Us Button](https://no-cache.hubspot.com/cta/default/637862/643835ce-1d72-4dda-8518-1b00aed21a9e.png)](http://cta-redirect.hubspot.com/cta/redirect/637862/643835ce-1d72-4dda-8518-1b00aed21a9e)       [![Mide Technology](https://www.mide.com/hubfs/Logos/hutchinson-mide-color-white-web.svg)](https://www.mide.com/?hsLang=en) **Mide Technology Corporation** 475 Wildwood Avenue Woburn, MA 01801, USA **Phone:** [+1 (781) 306-0609](tel:1781306-0609) **Email:** [Contact Us](https://www.mide.com/contact-mide?hsLang=en) [![Mide Technology](https://www.mide.com/hs-fs/hubfs/Logos/hutchinson-logos-white-hutchinson-250.png?width=180&name=hutchinson-logos-white-hutchinson-250.png)](https://www.hutchinson.com/en) *Mide is a Hutchinson Company* - [**](https://www.facebook.com/pg/MideTechnology/posts/) - [**](https://www.youtube.com/user/MideTech) - [**](https://www.linkedin.com/company/mide-technology-corporation) ##### [about](https://www.mide.com/about-mide?hsLang=en) Midé Technology Corporation, founded in 1989, is an *Innovative, Agile* and *Proven* engineering company that develops, produces and markets high performance products and solutions.
