We are a family business, with a global presence, that values customer service and employee well-being over everything else. DILO GmbH was founded in Germany in 1951. The name DILO comes from the German word “dichtungslos”, which means “without o-rings”. DILO is a nod to our first product, self-sealing metal to metal couplings that ensure leak proof connections.
