Active in harsh environments requiring no lubrication, extreme low temperatures, chemical resistance, and heat resistance! A substitute for O-rings and oil seals!

The "spring-loaded seal" is a high-performance resin seal that combines the low friction properties of PTFE with the high elasticity of a spring. A metal spring with excellent corrosion resistance is embedded inside a precisely machined jacket, providing sufficient elasticity to the jacket through the spring's load, which helps prevent deformation of the cover wall due to cold flow, wear, and expansion or contraction from temperature changes. Additionally, very important for the use of this product are the hardware conditions (surface roughness, hardness, compatibility due to differences in conditions, etc.). Our company has accumulated know-how from over 35 years of experience in selling spring-loaded seals. We can respond to your challenging applications, including requests to replace existing seals or extend maintenance periods.

Responding to the needs for leak improvement and longevity with product strength, improvement technology, and support capabilities. There is a proven track record of reducing the maintenance frequency of hydraulic cylinders.

【Products Offered】 ◎ Spring-loaded seals… Combining a high-performance resin jacket primarily made of PTFE with a metal spring, these seals can be used for both fixed and moving applications. They are capable of withstanding temperatures up to 300°C and have a proven track record of reducing the frequency of packing replacements in hydraulic cylinders. ◎ Cinchseal… A mechanical seal that accommodates shaft runout of ±3mm. ◎ Arrowhead seals… Specifically designed for use in grooves. They prevent sticking by adjusting the contact area, providing retention, and adhering to the groove. Compliance with food sanitation laws is also possible. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

We propose a seal packing that solves the issues of medical device performance and maintenance costs. *A catalog with application examples is currently being offered.

◎Spring-loaded seals… These combine a high-performance resin jacket primarily made of PTFE with a metal spring, making them suitable for both fixed and dynamic sealing applications. They can handle a wide temperature range from -269°C to +300°C and are compatible with various chemicals and organic solvents. ◎Composite resin packing… This is a composite resin packing that combines resin with rubber or metal. It allows for the creation of sealing packings that leverage the advantages of each material, such as the slip and wear resistance of resin and the elasticity and flexibility of rubber. 【Application Examples】 ■ Cryogenic equipment ■ Semiconductor manufacturing equipment (film deposition systems, transport systems, cleaning systems) ■ Dosing and coating equipment ■ Medical and analytical devices, HPLC ■ Sanitary equipment (food and cosmetic filling machines, kneaders), etc. *For more details, please refer to the <Download Catalog>.
