The assistance provided by Martec during the project was invaluable. Their prompt service enabled us to arrive at a solution within the short time scales of our project, and their advice on the type of vacuum grease to use and how to prepare the contact surfaces to ensure proper sealing was much appreciated. Martec was also most helpful in scheduling the manufacturing of the connectors, which are usually only manufactured to order.


Our engineers reported that the resulting products are some of the “coolest bits of technology that they have worked on” and they are truly a “design win”. On the whole the quality of the product far exceeded our expectations – the levels of finish are exceptional and met all of our design criteria. Martec is an excellent partner.
