    Metal parts

    The standard Fischer Connectors shells are nickel plated brass with natural (silver) chrome finish. Black chrome finish is available as an option. Internal piece parts are nickel plated brass. When warranted by an extreme environment, in most cases stainless steel can be substituted for all metal parts.

    Insulator and sealing

    Contact blocks and other insulators for our standard connectors are manufactured from high performance engineering plastic materials. The standard materials of each connector series are listed here. Ceramics and other dielectrics are available on special order.

    Elastomer seals

    Sealed connectors are fitted with O-rings and cable sealing gaskets. The standard materials are:
    • Viton® for O-rings
    • TPE (Thermoplastic Elastomers) for cable seals, protective sleeves and strain reliefs.

    Please note that as an elastomer reaches its lower temperature limit, it becomes rigid and loses the flexibility required for connector mating and unmating. If sealed connectors have to be manipulated at low temperatures, the O-rings in the mating area must be of a material with a considerably lower temperature limit. The elastomers listed below represent presently available materials, which Fischer can substitute when required by an application. Not all materials are available in all shapes and sizes so please check with us for details.
