Nitrile Rubber Gasket

1.1 Introduction

• Nitrile Rubber Gaskets (NBR / Buna-N) are engineered for sealing environments involving oils, fuels, lubricants, and petroleum-based fluids.
• They deliver dependable mechanical strength, stable compression performance, and leak prevention under continuous operation.
• Produced by precision molding or die-cutting, they ensure uniform thickness and consistent sealing quality.
•               

1.2 Material Characteristics

• Nitrile rubber is a copolymer of butadiene and acrylonitrile, providing excellent hydrocarbon resistance.
• Available in low-, medium-, and high-ACN formulas for improved fuel resistance or better flexibility at low temperatures.
•  

2.1 Chemical Resistance

• Exceptional resistance to oils, grease, diesel, gasoline, and mineral oils.
• Good resistance to hydraulic fluids and industrial lubricants.
•  

2.2 Mechanical Strength

• High tensile strength and abrasion resistance.
• Low compression set for reliable sealing after long-term use.
•  

2.3 Temperature Resistance

• Working range from −30°C to +110°C.
• Optional low-temperature NBR for improved flexibility.
•  

3.1 Reliable Oil-Sealing Performance
