We rank first in the market share nationwide (approximately 50 percent)in manufacturing a wide variety of joints for hydraulic piping used for power shovel etc.

Joints and fittings for high-pressure piping

Joints and fittings for high-pressure piping used as the components of construction machinery etc


Construction machinery and agricultural machinery such as power shovels, cranes, etc transmit their power by hydraulic hoses. One power shovel has about 120 joints used for these hydraulic hoses. We manufacture the joints for high-pressure piping used for power shovels and other machinery. These joints and fittings for machinery must be extremely durable enough to resist high inner pressure up to 200 to 400 kilograms per one square centimeter to prevent accidents or breakdown. To meet these tough conditions, we have developed and manufactured joints and fittings with stable quality applying our high technology of manufacturing products with reliable quality to resist harsh environment.
