What Fluorosilicone O-Rings Offer
Fluorosilicone (FVMQ) O-Rings are military-compliant sealing solutions made with a unique hybrid material combining silicone’s flexibility and FKM’s chemical resistance. They provide excellent sealing performance in applications with extreme temperature fluctuations and various chemicals.
Features & Benefits
- Wide Temperature Range (-100°F to 350°F / -74°C to 177°C): Provides reliable sealing in both high and low-temperature environments, ensuring performance across a broad range of conditions.
- Improved Chemical Resistance: Offers similar chemical resistance to FKM with added flexibility at low temperatures, making them suitable for sealing fuels, oils, and various other chemicals.
- Enhanced Low-Temperature Flexibility: Unlike standard FKM O-Rings, fluorosilicone O-Rings maintain flexibility at extremely low temperatures, ensuring an effective seal even in cold environments.
- Highly Resistant to Fuels and Oils: Offers excellent resistance to fuel, mineral oils, and low molecular weight aromatic hydrocarbons.
- Compliant: Fluorosilicone meets Mil-DTL-25988 specifications and is resistant to jet fuel, so it can be used in military aerospace applications.
Potential Applications & Industries
Fluorosilicone O-Rings are ideal for sealing applications that involve extreme temperatures and exposure to chemicals. They are commonly used in fuel systems, hydraulic systems, and engine components to prevent leaks and maintain system integrity. These O-Rings also seal fluid reservoirs and fuel lines, ensuring reliable performance in harsh environments where low molecular weight aromatic hydrocarbons or mineral oils are present.
Fluorosilicone O-Rings are widely used in industries like aerospace, transportation, military, and oil and gas.
In the aerospace sector, they are critical for sealing fuel systems and hydraulic circuits. In automotive and military applications, they maintain seal integrity in extreme environments, preventing leaks in fuel lines and fluid systems. The oil and gas industry relies on these O-Rings for sealing applications in rigs, pipelines, and valves where fuels and mineral oils are handled under various temperature conditions.
Design Specifics & How The Product Works
Fluorosilicone O-Rings are made from a specialized blend of silicone and FKM materials, combining the best attributes of both. The silicone component provides excellent low-temperature flexibility, while the FKM component contributes superior chemical resistance. The hybrid construction ensures that the O-Rings perform reliably even under harsh environmental conditions, offering both durability and elasticity in sealing applications where other O-Rings might fail.
What Makes Fluorosilicone O-Rings So Effective? Fluorosilicone O-Rings maintain their sealing capability across a wide range of temperatures and resist a variety of aggressive chemicals.
