Product Advantages
Forever Seals' stainless steel oil seals stand out in the market with a unique combination of premium materials and engineering excellence. The stainless steel outer casing ensures exceptional structural strength and resistance to rust, while the PTFE lips deliver unmatched chemical inertness—resisting acids, alkalis, solvents, and oxidizing agents. Unlike traditional rubber seals, they operate reliably in extreme temperatures ranging from -200℃ to +350℃, making them ideal for high-heat or cryogenic environments. With ultra-low friction coefficients (0.02) and self-lubricating properties, these seals minimize wear on rotating shafts, extending equipment lifespan. Available in single, double, or multiple lip configurations, they offer flexible solutions for varying pressure and sealing requirements.
Working Principle
The sealing efficiency of Forever Seals' stainless steel oil seals relies on the unique memory and contraction properties of PTFE. During manufacturing, the PTFE lips are stretched into a flared shape; when in operation, frictional heat triggers the material’s inherent memory, causing the lips to shrink continuously. This constant contraction ensures a tight, adaptive seal around the rotating shaft, compensating for minor wear or shaft irregularities. The stainless steel casing provides rigid support, preventing deformation under pressure and ensuring the lips maintain optimal contact with the shaft surface—even in high-vibration or misalignment scenarios.

Application Range
These seals are engineered for demanding industrial environments where traditional seals fail. Key applications include:
Pumps (chemical pumps, hot oil pumps, vacuum pumps, air compressors)
Rotating equipment (reducers, gearboxes, bearings, mixers, blowers)
High-temperature machinery (furnaces, heat exchangers, engine components)
Corrosive environments (chemical processing plants, pharmaceutical equipment, marine systems)
Heavy-duty machinery (construction equipment, machine tools, industrial motors)
FAQ
Q: What is the difference between single-lip and double-lip seals?
A: Single-lip seals offer lower friction, suitable for low-pressure, general-purpose sealing. Double-lip seals include an additional barrier, making them ideal for high-pressure systems or applications requiring extra leakage protection.
Q: Can these seals be used with food-grade equipment?
A: Yes, Forever Seals offers food-grade PTFE lips and 316 stainless steel casings that meet FDA and EU 10/2011 standards, suitable for food processing or pharmaceutical machinery.
Q: How do I choose the right lip configuration for my equipment?
A: Consider operating pressure (double lips for >0.3MPa), shaft condition (multi-lip for poor roundness), and environment (single lip for low-friction, high-speed scenarios). Our technical team at Forever Seals can assist with custom recommendations.
Q: What is the maximum pressure these seals can handle?
A: Standard models handle up to 1.0MPa; specialized high-pressure variants (with reinforced lips) from Forever Seals can withstand up to 3.0MPa.
