Spring-loaded seal / PTFE seal packing and gasket
Active in harsh environments requiring no lubrication, extreme low temperatures, chemical resistance, and heat resistance! A substitute for O-rings and oil seals!
This is a sealing packing that combines the properties of PTFE (low friction, heat resistance, chemical resistance, etc.) with the followability provided by the elastic force of a spring. We will respond to various conditions such as "liquid hydrogen," "abrasive fluids," "non-lubricated sliding," and "high speed and high pressure" with Seal Tech's 35 years of sales experience and know-how tailored to your applications! Seal Tech's proposed spring-loaded seals will solve your sealing packing issues! 【Features】 ■ Usable for both fixed and moving seals ■ Compatible with most chemical agents and organic solvents ■ Usable from ultra-low temperatures of -269°C to high temperatures of +316°C ■ Usable from high vacuum to high pressure (inquiry required) ■ A wide range of sealing materials (fillers) and spring materials available depending on the fluid and conditions ■ Lineup according to JIS-P size for moving O-ring groove dimensions * Due to machining, we can also accommodate other groove standards and special groove dimensions and shapes. ★ Our company has accumulated know-how regarding "hardware conditions and compatibility" through years of experience. This is also very important for selecting the appropriate seal design (performance, lifespan, etc.). Please feel free to consult us about your applications (usage conditions) and requests.
basic information
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.

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. We sincerely ask for your continued support and patronage.
