The Double Fittings are made of stainless steel and are designed by our own engineers. Everything produced by DERC is made according to drawings and has its own unique part number. It is designed according to the latest quality standards and requirements for the high pressure water jetting, oil and gas industry. For safety and traceability all products we produce are marked with a part number, maximum working pressure and thread connection.


All the products we produce are manufactured in our up to date machine park according to the latest quality standards. All necessary control and measurement checks have been performed before the products leave our factory. Our production staff is trained in the latest production standards and techniques.

Testing and Certificates

The products that DERC Salotech engineers and manufactures are being tested to withstand the maximum working pressure which they are designed for. We also test our standard products by means of hydro static pressure tests. These hydro static tests are performed in our own machine park as well. All products produced by us can be supplied with a test certificate, if required.
