Polytetrafluoroethylene (PTFE) stainless steel oil seals, also known as PTFE iron housing oil seals, are upgraded alternatives to rubber skeleton oil seals, designed to cope with extreme working conditions. The product combines the corrosion resistance and high strength of stainless steel with the excellent chemical stability, self-lubrication and high and low temperature resistance of PTFE. It is an ideal sealing solution for the chemical industry, high-temperature operating environments and high-precision machinery.
Advantages
Excellent chemical stability: PTFE is resistant to almost all chemical media, including strong acids, strong bases, strong oxidizers and organic solvents, ensuring long-term stable work in a variety of complex environments. Ensure long-term stable work in a variety of complex environments.
Wide temperature working performance: it can work normally in a wide temperature range from -200℃ to +350℃, which is far more than ordinary rubber oil seals, and meets the sealing requirements under extreme conditions.
Extremely low coefficient of friction: the coefficient of friction of PTFE material is only 0.02, which is 1/40 of that of rubber, significantly reducing the friction heat, minimizing the energy consumption, and prolonging equipment Extend the service life of the equipment.
Excellent self-lubrication: the surface has excellent self-lubrication, almost does not adhere to any sticky substances, reducing maintenance costs and improving the operating efficiency of equipment.
High abrasion resistance: through the filler modification treatment (such as adding glass fiber, carbon fiber, graphite, etc.), PTFE’s Wear resistance is greatly improved to ensure long-term reliable sealing.
Springless design: Unique wide-lip power structure, without the need for spring assistance can be tightly adhered to the shaft surface, reduce wear and tear, improve sealing effect.
High-pressure sealing capability: The double-lip design can withstand fluid pressure up to 3MPa, far exceeding traditional rubber oil seals, suitable for high-pressure working conditions.
Applications
PTFE stainless steel oil seals are widely used in air compressors, vacuum pumps, automobile engines, motors, air conditioners, mixers, automated precision machinery, Robots, chemical processing equipment, pharmaceutical and food processing equipment, etc. It is especially suitable for harsh environments where traditional rubber oil seals are unable to cope with.
