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.


It is always refreshing to find a vendor like Martec that acts as a partner in the product development process.  They have been responsive, show enthusiasm, and have demonstrated dedication in delivering a product that meets our needs and the needs of our end customers.
