FPM O-Ring 37.5x3.55 FKM Viton

Applications in Hydraulic and Industrial Systems

The FPM O-Ring 37.5x3.55 made of FKM (Viton) is a high-performance industrial sealing component designed for demanding operating environments. This rubber gasket is commonly used as a static seal in hydraulic and pneumatic systems, fuel installations, pumps, valves, and various industrial assemblies exposed to aggressive media.

Thanks to its chemical resistance, this O-Ring provides reliable sealing in contact with mineral oils, greases, fuels, solvents, and many industrial chemicals. It is widely selected for hydraulic and automotive seals where standard NBR rubber seals may not offer sufficient durability.

Material Properties - FKM / Viton

FKM (fluoroelastomer, commonly known as Viton) ensures high durability and long service life even at elevated temperatures. Typical working temperature range is approximately -20°C to +200°C, making this O-Ring suitable for high-temperature industrial applications.

The material offers excellent resistance to oils and grease, low gas permeability, and strong aging resistance. As a result, this shaft-independent static seal is frequently used in chemical processing, automotive, energy, and heavy industrial applications requiring reliable technical sealing components.

FAQ

1. What is the difference between FKM and NBR O-Rings?
FKM O-Rings provide significantly higher temperature and chemical resistance compared to NBR rubber seals.

2. Is this O-Ring suitable for hydraulic systems?
Yes, it is commonly used in hydraulic and pneumatic applications, especially where high temperatures or aggressive fluids are present.

3. What temperature can FKM withstand?
Typically from about -20°C up to +200°C, depending on operating conditions.

4. Can FKM O-Rings resist fuels and solvents?
Yes, FKM offers excellent resistance to fuels, oils, and many industrial chemicals.

5. How do I select the correct O-Ring size?
Match the inner diameter and cross-section to the groove dimensions and the sealing surface diameter. In this case: 37.5x3.55.
