After years of being frustrated by the existing coolant hose products on the market; all of which suffered from a variety of shortcomings, Arnold Lockwood conceived the idea for the modular hose that became Loc-Line®. These shortcomings included, metal coolant hoses that would not stay where they were positioned and plastic hoses with metal positioning rods that broke.

In 1981 Lockwood Products was formed to develop and distribute Loc-Line®. The first products were shipped in August of 1983.

Loc-Line® quickly became the standard for coolant delivery around the world and was easily recognized by our Blue and Orange colors.

Today Loc-Line® is still the leader in modular hose and continues to innovate in the modular hose field. Loc-Line® is used not only as a coolant hose but for air delivery, smoke and dust removal vacuum systems, agriculture,  third arm uses including positioning cameras, lights and items for handicap assist.

Lockwood Products originated the modular hose concept and remains the standard for the industry.
