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.

Replaceable with O-rings and oil seals! Performs well in harsh environments requiring no lubrication, extreme low temperatures, chemical resistance, and heat resistance!
