Product Description

Product Name: NBR O-ring, also known as NBR O-ring and nitrile O-ring, is the most widely used O-ring material in the world. Due to its low cost, good mechanical properties, water resistance, and resistance to most base oils, lubricants, and some fuels, it is the default choice for many pneumatic and hydraulic systems. Nitrile rubber O-rings have good wear resistance, tensile strength, and resistance to compression permanent deformation.
Due to its excellent resistance to petroleum products and the ability to be used in combination within a temperature range of -35 ° C to+120 ° C (-30 ° F to+250 ° F), nitrile/NBR is the most widely used elastomer in the sealing industry today. In addition, many rubber specifications for fuel resistant and oil resistant O-rings require the use of nitrile compounds.
Temperature range: NBR/nitrile O-ring can resist oil-based hydraulic oil, fat, and oil. Temperature range -30 ° C to+120 ° C, hardness tester/hardness 70.

Product Description

 

                Nitrile rubber (NBR)

 

wear-resisting

Oil resistant

waterproof

heat-resisting

Rubber with good friction resistance, oil resistance, wide application range, and low cost is commonly used in the production of lubricating oil tanks, fuel tanks, and in fluid media such as pressurized oil, gasoline, and silicone oil in petroleum systems, with a suitable temperature range of -20~120 ºC.
