Corporate Profile


Creations and Challenges

HKT has been doing business with many domestic manufacturers of trucks, buses, and large vehicles since it started manufacturing air horns (warning sound devices which use compressed air) for the first time in Japan.
Our primary products are electromagnetic selector valves used for trucks and buses that require higher standards to withstand severe environments. The basic function of the valves is to "start and stop" the flow of compressed air, negative pressure, hydraulic pressure, natural gas, and coolant water. HKT also provides to customers products such as glow plugs and post-processing devices for diesel engine exhaust.

We aspire to be "a company that is capable of skillfully crafting and offering a variety of small quantity products better than any other companies, at minimum cost to our customers." To achieve this goal, we design products according to customer requests, assessing our product performance under individual environments based on required specifications so that we can offer high performance and quality products to customers. Focusing on our motto of "make every effort to produce products on a commercial basis," HKT will continue its challenge to create products in every field utilizing know-how which we nurtured in the large motor vehicle industry.
