Our company has provided various industrial products centered around industrial hoses and flexible joints to many customers and industries. The purpose of this is none other than to enhance the important values of various equipment in the plant business: "safety," "functionality," and "efficiency." Furthermore, we are currently advancing the design, development, manufacturing, and sales of hose products and lined piping materials primarily made of Teflon (PFA/PTFE) for processes that require more precise selection of liquid contact materials. We are promoting development projects for products with "high safety," "high functionality," and "high efficiency," which is possible precisely because our company has faced and supported the field. Using the knowledge and experience we have cultivated so far, we aim to "confront more challenges, grasp essential needs, and flexibly solve problems." Under this policy, our company will continue to be a "group with will" and maintain the unwavering efforts since our founding.
