FPM, ACM, and PTFE Oil Seals – Versatile Rotary Shaft Seals for Extreme Conditions
Selecting the right oil seal material is crucial for ensuring the reliability and durability of rotary shaft seals in various industrial and automotive applications. Oil seals made from FPM (FKM, Viton®), ACM, and PTFE are three of the most popular sealing solutions, each offering unique properties tailored to specific needs and working conditions.
FPM (FKM, Viton®) – Oil Seals for Extreme Temperatures and Chemicals
FPM, also known as FKM or Viton®, is a fluorocarbon material highly valued for its exceptional resistance to extreme temperatures and aggressive chemicals. These oil seals are ideal for rotary shafts in applications where seals must perform in temperatures ranging from -20°C to +200°C, with short-term exposure up to +230°C. FPM offers excellent resistance to oils, fuels, solvents, and other industrial chemicals, making it the preferred choice for demanding environments in the automotive, chemical, and energy industries.
Key Features of FPM Rotary Shaft Seals:
- Temperature Resistance: Operates efficiently between -20°C and +200°C, withstanding short-term peaks up to +230°C.
- Chemical Resistance: Exceptional resistance to oils, fuels, and aggressive chemicals.
- Mechanical Stability: High mechanical stability under dynamic loads and pressures.
Applications:
- Automotive: Widely used in engines, gearboxes, and other critical automotive components where high temperatures and chemical exposure are common.
- Chemical Industry: Ideal for sealing valves, pumps, and equipment handling corrosive substances.
- Energy Sector: Essential for turbines and generators exposed to high temperatures and pressures.
ACM – Reliable Rotary Shaft Seals for High-Temperature Applications
ACM (Acrylic Rubber) rotary shaft seals are specifically designed for applications that require durability in high-temperature environments and exposure to oils. ACM oil seals operate effectively in temperatures ranging from -25°C to +150°C, making them an excellent choice for automotive and industrial settings where long-term heat exposure and contact with lubricants are concerns.
Key Features of ACM Rotary Shaft Seals:
- Temperature Resistance: Suitable for applications between -25°C and +150°C.
- Oil Resistance: High resistance to oils, greases, and other automotive fluids.
- Mechanical Stability: Maintains sealing integrity under various pressures and dynamic conditions.
Applications:
- Automotive: Commonly used in engines, transmissions, and systems exposed to heat and oils.
- Industrial Machinery: Ideal for machinery operating in high-temperature environments with lubricant exposure.
PTFE (Teflon®) – Unmatched Rotary Shaft Seals for Extreme Conditions
PTFE (Polytetrafluoroethylene), commonly known as Teflon®, offers unparalleled resistance to extreme temperatures, chemicals, and environmental factors. PTFE rotary shaft seals are designed for the most demanding applications where traditional seals might fail. They operate effectively in temperatures ranging from -200°C to +260°C, providing reliable sealing in the harshest conditions.
Key Features of PTFE Rotary Shaft Seals:
- Temperature Resistance: Functions across a wide range from -200°C to +260°C.
- Chemical Resistance: Resistant to virtually all chemicals, including acids, bases, and solvents.
- Low Friction: Minimizes wear and extends the lifespan of the sealing system.
Applications:
- Chemical Industry: Used in sealing valves, pumps, and equipment exposed to aggressive chemicals.
- Aerospace: Essential for aircraft engines and components requiring reliability under extreme conditions.
- Pharmaceutical and Food Processing: Non-toxic and non-reactive, ideal for maintaining cleanliness and safety.
