PTFE Stainless Steel Oil Seals
PTFE (Polytetrafluoroethylene) Stainless Steel Oil Seals are engineered to provide exceptional sealing performance in a variety of industrial applications. These seals combine the chemical resistance and low friction of PTFE with the strength and durability of stainless steel, making them ideal for environments that demand both reliability and longevity.
PTFE Stainless Steel Oil Seals are available in the following configurations: single-lip, double-lip, triple-lip, and four-lip. The lip orientation can be forward, reverse, or a combination of both forward and reverse.
The lip portion is made of PTFE composite material, which has obtained FDA environmental certification—this significantly enhances the wear resistance and fatigue resistance of the sealing lip. The metal case (or “skeleton”) is constructed from 304/316 stainless steel, which offers excellent corrosion resistance.
PTFE is a material that is well-known due to its outstanding resistance to chemical attack and its low-friction properties. flexible fluoropolymer, which is great for sealing jobs with a great deal of work. This unique molecular design of PTFE offers an exceptional resistance to chemicals and temperatures and environmental elements. This makes it the ideal material to use in critical industrial processes.
Main advantages of PTFE seals include:
High chemical resistance
Wide operating temperature range, –90 to +260 °C (with instantaneous tolerance up to 300°C)
Withstand speeds up to250m/s
Withstand pressures up to 1MPa
Key Features of PTFE Stainless Steel Oil Seals
Inner Wall Grooves
The inner wall of the PTFE oil seal is engraved with thread grooves in the opposite direction of the shaft. When the shaft rotates, an inward thrust is generated to prevent the seal from moving away from the shaft, ensuring a tight and secure fit.
Top Material
PTFE oil seals exhibit excellent anti-friction properties, making them particularly suitable for applications that operate in oil-free or low-oil environments. Even after long periods of inactivity, these seals can immediately resume operation with low friction, ensuring smooth and efficient performance.
Wear-Resistant Hardware
The high-strength hardware used in PTFE stainless steel oil seals is designed to be robust and wear-resistant. It maintains its integrity over extended periods of use, resisting rust and corrosion, which is crucial for the longevity of the seal.
Enhanced Sealing Design
Based on the single lip design, an additional sealing lip is incorporated with an extra lip opening. This design enhances the sealing performance by providing a more effective barrier against leaks.
Improved Pump Suction
An oil return line is added to the inner lip design, which helps to form a pump suction effect and increases the overall sealing performance. This feature is particularly beneficial in applications where maintaining optimal pressure is critical.
Applications of PTFE Stainless Steel Oil Seals
PTFE Stainless Steel Oil Seals are widely used in a variety of applications due to their versatility and reliability:
Screw Air Compressors: These seals are used to prevent oil leakage and ensure efficient operation in air compressors.
Vacuum Pumps: They provide tight seals in vacuum pumps, maintaining the necessary vacuum levels without contamination.
Motors and Air Conditioners: In these applications, the seals help maintain the integrity of the system by preventing fluid leaks.
Automated Precision Machinery: The low friction and wear resistance of these seals make them ideal for precision machinery where smooth operation is critical.
