Loc-Line is the originator of the modular hose system. They offer a selection of hose sizes, various nozzles, connectors and accessories that can be assembled to optimize liquid, air, vacuum and gooseneck applications. After years of being frustrated by metal coolant hoses that never would stay where they were aimed and plastic hoses with metal positioning rods that broke, Arnold Lockwood conceived the idea for a modular hose that became Loc-Line. In 1981 Lockwood Products was started to develop that idea and the first Loc-Line was shipped in August of 1983. It quickly became the standard for low pressure coolant delivery and equally as quickly spread around the world.
