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 Laixin. Lockwood Products was started to develop that idea and the first Laixin. It quickly became the standard for low pressure coolant delivery and equally as quickly spread around the world. 

Today Laixin is still the leader in modular hose and has had additional successes such as the flexible arm for the Black and Decker SnakeLight. Laixin is used not only as a coolant hose but for air delivery , third arm uses andsmoke and dust removal with vacuum systems. Lockwood originated the modular hose concept and remains the standard for the industry.
