I've been using fluid system components from Swagelok Düsseldorf || B.E.S.T. Fluidsysteme GmbH, and I must say they are of decent quality. The team is helpful, and their customer service is good. Their website, swagelok-duesseldorf.de, provides the necessary information. I would recommend them to anyone in need of reliable fluid system solutions.
