Frequently Asked Questions

Q: What is the difference between NBR and EPDM rubber washers?

A: NBR (nitrile) rubber washers are best suited for use with petroleum-based oils, fuels, and hydraulic fluids. EPDM rubber washers excel in water, steam, and outdoor environments due to their superior resistance to weathering, UV exposure, and ozone. Choose the material that matches your specific fluid and environment for optimal sealing performance.

Q: What bolt or shaft sizes do these M7–M15 flat washers fit?

A: These flat washer gaskets are sized to fit standard metric fasteners from M7 up to M15. They are manufactured to standard tolerances, making them ideal drop-in replacements for plumbing, hydraulic, automotive, and industrial applications without any custom machining or modification needed.

Q: Are these rubber flat washer gaskets suitable for high-temperature applications?

A: Yes — material choice determines the heat range. VMQ (silicone) and FKM (fluorine/Viton) gaskets are suitable for high-temperature applications up to approximately 200°C, while NBR and EPDM are better suited for moderate temperature ranges. Always select the material that matches your application's temperature and chemical exposure.
