Frequently Asked Questions

Q: What material are these O-rings made from, and why does it matter?

A: These O-rings are made from FKM (Fluorocarbon/Fluorine) rubber, a high-performance elastomer known for its outstanding resistance to heat, oils, fuels, and chemicals. Compared to standard NBR or EPDM rubber O-rings, FKM offers significantly better durability in harsh environments — making it the go-to choice for automotive, industrial, and chemical-handling applications.

Q: What does "CS2mm" mean for these O-rings?

A: "CS" stands for Cross-Section, which refers to the diameter of the O-ring's circular profile. A CS of 2mm means the rubber cord has a 2mm thickness. This measurement is critical when selecting the correct O-ring for a specific groove or fitting to ensure a proper, leak-free seal.

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

A: Yes. FKM fluorocarbon rubber is specifically engineered to withstand elevated temperatures that would cause standard rubber seals to degrade or fail. These green FKM O-rings are an excellent choice for engine components, industrial machinery, and other high-heat environments.

Q: Can these O-rings be used with chemical fluids and oils?

A: Absolutely. FKM rubber has superior resistance to a broad range of chemicals, including petroleum-based oils, hydraulic fluids, fuels, and many industrial solvents. Always verify chemical compatibility for your specific application before use.
