    About Supplier

    Your Best Partner, Jeong Woo Coupling with MP JOINT - the Best Pipe Coupling and Clamp

    We have been approved and listed by ISO 9001, several major classification societies and other agencies. We are registered at Korea Water and Wastewater works Association (KWWA), Japan Water Works Association (JWWA), and Fire Equipment and Safety Center of Japan (FESC). Also, we are designated as World-Class Product Producing Company by Ministry of Trade, Industry and Energy of Korea.

    Through developing our own technology, currently we are exporting 70% of our production to 40 countries such as Japan, England, France, the USA, Singapore, Norway, Sweden, and Australia. Domestically, we do business with a large number of big and small companies including Samsung, Hyundai, Daewoo, Doosan, LG, and SK.

    While other couplings are used for the straight pipe lines only, we developed and obtained a patent for the product, MJET, which connects an elbow or a T part to a pipe.

    Regarding the pipe repair clamp, we developed MJER for elbow repair for the first time in the world. In addition, another world's first product - MJHT, bolt-rotating hinge type for repairing straight pipe lines - has come to make piping work much easier and quicker.

    We will keep developing technology and making products which help you do piping work quickly, easily, economically, and safely.
