FAQs
1. What is the difference between a rubber washer and a gasket?
Rubber washers are typically smaller, simpler seals used with fasteners. Gaskets are larger, more complex seals used to seal between two surfaces, often in larger assemblies.
2. How do I choose the right material for my white rubber washer?
Consider the application’s operating conditions, including temperature, chemical exposure, and required durability. The material properties table above helps in making the right selection.
3. Can I get custom-sized white rubber washers from Chinese manufacturers?
Yes, many Chinese manufacturers offer custom-designed and manufactured rubber washers to meet specific requirements. This is a common service offered by companies like Lindas Rubber and Hebei Shida.
4. What are the common manufacturing methods for white rubber washers?
Common methods include molding (for complex shapes), die-cutting (for simple shapes), waterjet cutting (for intricate designs), and lathe cutting (for precise dimensions). Qianlang Rubber, for example, uses various manufacturing methods.
5. How long does it typically take to receive an order of white rubber washers from China?
Lead times vary depending on the quantity, customization requirements, and the manufacturer. Some manufacturers, like Lindas Rubber, claim delivery within 1-2 weeks, but this can be longer for larger orders or custom designs.
