Frequently Asked Questions

Q: What material are these flat gaskets made from?

A: These gaskets are made from Fluorine Rubber (FKM), a high-performance elastomer known for its strong resistance to oils, fuels, hydraulic fluids, and many aggressive chemicals. This makes them suitable for automotive, industrial, and plumbing sealing applications.

Q: What sizes are available for these fluorine rubber washer rings?

A: The inner hole diameters range from M2 to M42mm, covering a broad spectrum of standard fastener and pipe sizes. Thickness options include 1mm, 1.5mm, 2mm, 2.5mm, and 3mm, giving you flexibility to select the exact fit for your project.

Q: Are these gaskets suitable for high-temperature environments?

A: Fluorine Rubber (FKM) is well-regarded for its thermal stability and is commonly used in applications that involve elevated temperatures, such as automotive engine components and hydraulic systems. Always verify the specific temperature and pressure ratings for your particular use case before installation.

Q: How do I choose the right thickness for my application?

A: The correct thickness depends on the gap or clearance between the mating surfaces you need to seal. Measure the recess or gap depth and select the gasket thickness that provides a firm, compressed fit — typically 1mm to 3mm for standard fastener assemblies. When in doubt, opt for a slightly thicker gasket to ensure adequate compression and a leak-free seal.
