Frequently Asked Questions
Q: What is the difference between NBR, VMQ, and FKM rubber flat gaskets?
A: NBR (Nitrile) gaskets are ideal for general-purpose sealing against oils, fuels, and water. VMQ (Silicone) gaskets excel in extreme temperature environments and are often used in food-grade applications. FKM (Fluorine/Viton) gaskets offer the highest resistance to aggressive chemicals and elevated heat, making them suitable for demanding industrial and automotive environments. Choose the material that best matches your specific fluid and temperature conditions.
Q: What sizes are available for these flat rubber gaskets?
A: These Ouling flat gaskets are available in a wide standard size range from M2 to M42. If you require a specific size or need a large custom order, please contact our customer service team who can assist with detailed sizing information and custom manufacturing options.
Q: Are these flat gaskets suitable for waterproof sealing applications?
A: Yes. All three rubber compounds — NBR, VMQ, and FKM — provide excellent waterproof sealing performance. The flat gasket design ensures a tight, even seal when compressed between mating surfaces, effectively preventing moisture and fluid ingress in plumbing, mechanical, and industrial assemblies.
Q: Can I order these rubber gaskets in bulk or with custom dimensions?
A: Absolutely. Ouling offers customized flat gasket production for large-quantity orders. Please reach out to our customer service with your required dimensions, material preference, and quantity, and we will provide a tailored solution for your project.
