Hydraulic Couplers (High Pressure)

A hydraulic (high pressure) coupler is a term that refers to a plug with a joint called a coupler. Many of them use heat-treated special steel as a material and are strong against vibration and shock. Some are equipped with an automatic open / close valve, and are used in equipment that uses a large amount of flow even in hydraulic pressure. There are plugs and sockets, and they are used for various purposes such as removing hoses from hydraulic equipment and piping for high-pressure gas. There are many types of screw diameters and many are easy to handle.
