FAQs About NBR 80 O-Rings
1. What is the difference between NBR 70 and NBR 80?
NBR 80 is harder and more wear-resistant, making it suitable for high-pressure and heavy-load sealing, while NBR 70 offers better flexibility. Your choice depends on the operating environment.
2. Can you manufacture customized O-rings based on drawings or samples?
Yes. We accept CAD files, 2D/3D drawings, or physical samples. Our engineers can also help redesign for better performance.
3. Do NBR 80 O-rings resist oil and fuel?
Absolutely. NBR is one of the best elastomers for resistance to petroleum-based oils, lubricants, and fuels.
4. What is the lead time for bulk orders?
Typically 12–18 days after sample approval, depending on order quantity.
5. What is your minimum order quantity?
Our MOQ starts at 50 pcs, ideal for both wholesalers and small-volume OEM buyers.
