Frequently Asked Questions (FAQs)
Frequently Asked Questions About NBR O-Ring Factories in China
What are NBR O-Rings and why are they widely used
NBR O-Rings, also known as Nitrile or Buna-N O-Rings, are made from a copolymer of acrylonitrile and butadiene. They are widely used due to their excellent oil resistance, good mechanical properties, and affordability. These O-Rings are ideal for applications involving fuel, oil, gasoline, and other petroleum-based products.
What is the temperature range for NBR O-Rings
NBR O-Rings can operate within a temperature range of -40°C to 120°C (-40°F to 248°F). However, the higher the acrylonitrile content, the better the resistance to petrochemicals, but the worse the low-temperature performance.
What are the common applications of NBR O-Rings
NBR O-Rings are extensively used in various industries, including automotive, aerospace, and petroleum. They are often found in fuel tanks, lubricating oil tanks, and other applications involving fluid media like petroleum hydraulic oil, gasoline, and silicone oil.
How do I choose the right NBR O-Ring supplier in China
When choosing an NBR O-Ring supplier in China, look for manufacturers with ISO certifications (e.g., ISO 9001) to ensure quality standards. Check their product range, customization options, and customer service. Also, consider their experience and reputation in the industry, as well as their ability to provide samples and meet your specific needs.
Can NBR O-Rings be customized
Yes, NBR O-Rings can be customized to meet your specific requirements. Many Chinese manufacturers offer customized sizes, shapes, and colors. You can also provide your design drawings for custom production. This flexibility makes NBR O-Rings versatile for a wide range of applications.
