Green FKM O-Rings CS 2.4mm – Fluorine Rubber Seals & Gaskets

Green FKM Fluorine Rubber O-Rings – CS 2.4mm Seals & Gaskets

Keep your connections leak-free and long-lasting with these high-performance Green FKM (Fluorocarbon) Rubber O-Rings. With a cross-section thickness of CS 2.4mm, these precision-standard ring gaskets are engineered for demanding industrial and mechanical sealing applications where reliability truly matters.

Why Choose FKM Fluorine Rubber O-Rings?

• Exceptional Temperature Resistance: FKM (Viton®-type) fluorocarbon rubber withstands a wide operating temperature range, making these O-rings ideal for both high-heat and low-temperature environments.
• Outstanding Chemical Resistance: Highly resistant to oils, fuels, hydraulic fluids, solvents, and many industrial chemicals — perfect for fluid handling and sealing systems.
• Superior Wear Resistance: The durable FKM compound maintains its shape and elasticity under mechanical stress and repeated compression cycles, ensuring a long service life.
• Precision Standard Sizing: Manufactured to standard dimensions for easy identification and drop-in replacement across a wide range of equipment.
• Distinctive Green Color: The green color provides instant visual identification of FKM material, simplifying inventory management and maintenance workflows.
• Versatile Applications: Suitable for automotive, hydraulic, pneumatic, plumbing, and industrial machinery sealing tasks.

Frequently Asked Questions

Q: What does FKM mean and why is it important for O-rings?

A: FKM stands for Fluorocarbon rubber (also commonly known by the trade name Viton®). It is a high-performance elastomer known for its excellent resistance to heat, oils, fuels, and a wide range of chemicals. FKM O-rings are the preferred choice in demanding environments where standard rubber or NBR seals would degrade quickly.

Q: What is the cross-section (CS) of these O-rings and why does it matter?

A: The cross-section (CS) refers to the diameter of the O-ring's circular profile — in this case, 2.4mm. The CS determines how the O-ring fits within a groove and how much compression it provides. Choosing the correct CS is essential for achieving a reliable, leak-free seal in your specific application.

Q: Are these FKM O-rings suitable for high-temperature applications?

A: Yes. FKM fluorocarbon rubber O-rings are specifically engineered to handle elevated operating temperatures, typically up to around 200°C (392°F) depending on the specific compound and media. This makes them a top choice for automotive, industrial, and hydraulic systems exposed to heat.

Q: Can I use these O-rings with oil and fuel systems?

A: Absolutely. One of the key strengths of FKM rubber is its high resistance to petroleum-based oils, fuels, hydraulic fluids, and many solvents. These green FKM O-rings are well-suited for use in fuel lines, hydraulic systems, and oil-wetted environments.
