Aerospace Gaskets and Materials

We have been in the aerospace industry for over 30 years.  We sell to a variety of commercial and Government users in the traditional markets as well as space, military arms and other applications.  In these industries our parts are used in applications around engines / power, electrical systems and interior components.

We use a variety of materials based on the applications.  For engines and electrical systems, we use high-temp materials including some with electrical grades.  Examples include Nomex, Kapton, Teflon coated fiberglass, Viton, Glass melamine (G-7, G-10, etc), silicone, compressed non-asbestos materials and many others.  We also use EMI materials such as silver-impregnated silicone, flexible graphite and other proprietary EMI materials.  

For interior components, we use common gasket materials including industrial plastics such as Nylon, Polyethylene and Teflon as well as commercial-grade solid rubbers including nitrile, neoprene and silicone.
