FAQs
1. What is the difference between NBR and FKM O-rings?
NBR O-rings are cost-effective with good oil and fuel resistance but limited high-temperature performance. FKM O-rings are more expensive but excel in chemical and high-temperature resistance.
2. How do I choose the right hardness for a 50mm O-ring?
The required hardness depends on the application. Higher hardness offers better compression set resistance but reduced flexibility. Consider the pressure and surface finish of the mating parts.
3. What are the common quality control measures for 50mm O-rings?
Quality control includes visual inspection, dimensional measurement, material testing (tensile strength, hardness), and performance testing (leakage, compression set).
4. Are 50mm O-rings suitable for all applications?
No, the suitability depends on the specific application requirements. Factors like temperature, pressure, and chemical exposure determine the appropriate O-ring material and hardness.
5. Where can I find reliable suppliers of 50mm rubber O-rings in China?
Numerous reputable manufacturers and suppliers are available in China. Online B2B platforms and industry directories can help you locate and vet potential suppliers. Thorough due diligence is recommended.
