NBR (Nitrile Butadiene Rubber), commonly known as Buna-N, is the most widely used O-ring material in industrial sealing applications. It is a synthetic copolymer engineered for outstanding resistance to petroleum-based oils, fuels, and hydraulic fluids, which is why it remains the default choice for automotive, hydraulic, and general engineering systems across India. At Bharati Solutions, our NBR O-rings are manufactured and supplied from our Delhi NCR facility under ISO 9001:2015 certified quality processes, with more than 8,000 sizes held in stock for same-day dispatch.
Our NBR O-rings are manufactured to AS568, BS1806 and DIN3771 size standards, and we regularly supply metric and JIS B2401 sizes as well. Custom sizes and compounds are available on request, and every batch is quality-checked before dispatch to meet the dimensional and performance tolerances your application requires.
As an ISO 9001:2015 certified supplier based in Delhi NCR, we combine consistent material quality with fast turnaround. Our in-house stock of NBR compounds means most standard sizes ship the same day, and our technical team is available to help you select the right hardness and compound for your specific oil, fuel or abrasion resistance requirements.
