Inert to most fluids! Also used as a backup ring for rubber seals!
【Issues】 The commonly used packing materials are primarily rubber such as Viton and HNBR, which are considered suitable for high-temperature applications. However, when temperatures exceed 200°C, as is often the case with SN cylinders, deterioration is unavoidable. In severe conditions, there have been reports of cases where packing replacement is necessary every 2 to 3 weeks. 【Improvements and Effects】 The spring-loaded seal combines PTFE, which excels in heat resistance, sliding, and extrusion resistance, with the high-temperature spring characteristics of 17-7PH, achieving sealing performance and long lifespan that were difficult with conventional packings. Practical examples in Japan are steadily increasing, and many end users and cylinder manufacturers have adopted this solution. 【Examples】 (Lab Test) Test Conditions: Unloaded sliding test: 10 reciprocations (full stroke) - 9.8 MPa (100 kg/cm²) pressure resistance: 10 pressure tests (1 minute each) - 20.6 MPa (210 kg/cm²) pressure resistance: 10 pressure tests (1 minute each) *For more details, please refer to the PDF document or feel free to contact us.

Company information
We, Seal Tech Co., Ltd., entered into a sales agency agreement with FURON Corporation in the United States in June 1987 and began domestic sales of their SPRING ENERGIZED SEAL. Today, there is a growing demand for improved working environments, efficiency, and safety across all industrial sectors. However, even in this technologically advanced era, issues caused by fluid leakage persist, and we feel that the demands are increasing. Through the sale of fluid control equipment, our company has developed as a technical trading company that addresses such troubles and technical challenges, responding to the increasingly sophisticated and diverse needs, and contributing to Japanese manufacturing. To gain even greater trust and assurance from our customers, we obtained ISO 9001 certification on April 24, 2011, and are committed to continuous improvement and maintenance through the thorough establishment and operation of a "Quality Management System." Moving forward, we will continue to adopt a customer-oriented approach and strive to respond accurately and swiftly to our customers' needs through the development of products and technologies.
