Breakdowns of overseas machines can be quickly repaired with domestic parts! A conversion adapter that resolves compatibility issues and transforms the "waiting for overseas parts" that used to take weeks into "same-day recovery."
In the maintenance of overseas equipment operating in domestic factories and construction sites, the biggest obstacle is the "difference in screw standards." Standards unique to overseas (such as ISO/BSPP) are difficult to obtain domestically, and there are many cases where one has to endure high shipping costs and several weeks of line stoppage just to procure a single part from the home country. The "conversion adapter" provided by Du Yamamoto is a revolutionary product that instantly converts these overseas standards to the commonly used "domestic standards (such as JIS)" in Japan. This allows for the use of readily available general-purpose hoses and fittings in the country, enabling the restoration of machinery on the same day without waiting for parts to arrive. We maintain a constant stock of major sizes at our headquarters warehouse in Koto, Tokyo, and have established a system for same-day shipping at the earliest. In 2026, we will continue to support significant reductions in downtime in the maintenance of overseas machines as a partner in creating "unstoppable sites."

【No technical skills required, no leaks】 Convert international standards to domestic standards! A conversion adapter with a special structure that eliminates the need for sealing tape and offers high workability, allowing connections in tight spaces at any angle.
In the repair of overseas equipment, not only the differences in standards but also the "difficulty of work" pose challenges. The Do Yamamoto conversion adapter series features three characteristics that reduce the burden on the site. 1. Reliable sealing without technical skills: Adopting the "O-ring port" that seals with a rubber gasket (O-ring) instead of sealing tape. Regardless of the worker's experience, the risk of leakage can be minimized, no matter who installs it. 2. Direction adjustment in tight spaces: A lineup of models that can be adjusted to any direction after connection, even in the tight piping spaces of overseas machines. 3. Reduced running costs: Once converted to domestic standards, inexpensive domestic general-purpose products can be used for subsequent repairs, leading to reduced maintenance costs. As a specialized company in industrial hoses established in 1959, we solve all "disconnections" under strict quality control. If you are troubled by deficiencies in hydraulic piping for overseas machine tools, construction machinery, etc., please feel free to consult us.
