Introduction to Nitrile Rubber O Rings

Nitrile Rubber O Rings, also known as NBR O Rings or Buna-N O Rings, are one of the most commonly used sealing elements in industrial engineering applications. These circular elastomeric seals are designed to be seated in grooves and compressed between two or more parts during assembly, creating a tight and leak-proof seal.

In fluid power and mechanical systems, O Rings function as critical components that prevent leakage of fluids and gases under pressure. Because of their exceptional resistance to petroleum-based oils, hydraulic fluids, diesel, lubricants, and certain chemicals, Nitrile Rubber O Rings have become a standard choice across industries.

At Krishna Industries, we supply precision-manufactured Nitrile Rubber O Rings that meet the dimensional and performance requirements of diverse Indian industries. Our O Rings are produced using high-grade nitrile elastomer compounds that ensure excellent mechanical strength, abrasion resistance, and long-term durability.

What is Nitrile Rubber (NBR)?

Nitrile Rubber, technically known as Acrylonitrile Butadiene Rubber (NBR), is a synthetic copolymer composed of acrylonitrile and butadiene. The percentage of acrylonitrile content determines oil resistance and flexibility characteristics.

Key Chemical Properties:

• Excellent resistance to petroleum oils and fuels
• Good resistance to hydraulic fluids
• Moderate resistance to acids and bases
• Temperature range typically from -20°C to +120°C

Due to these properties, NBR O Rings are extensively used in automotive engines, compressors, pumps, valves, and industrial equipment across India.
