A groundbreaking product that integrates the JWWA B 120 "soft seal partition valve for water supply" with a continuous water branching pipe has arrived!

Since our establishment in 1970, we have been a manufacturer of special fittings dedicated to protecting lifelines, introducing numerous innovative products to the market. The ductile iron ball-shaped flexible expansion joint "Flexibender," released in 1980, demonstrated its seismic performance during the Great Hanshin-Awaji Earthquake and the Great East Japan Earthquake. The EM continuous water supply method "S-Gate" series, launched in 1999, has steadily achieved results in various countries around the world, including the United States and South Korea. We are committed to product development with free thinking, unconstrained by conventional wisdom, and contributing to the safety of lifelines.
