Due to its high abrasion resistance and endurance to ageing, the HNBR O-Ring 80 Shore A needs to be replaced less often thus saving on maintenance and replacement costs.  If durability and reliability are important the HNBR O-ring is a good investment.

Less Flexible in Extreme Cold

The HNBR O-ring 80 Shore A performs great in a variety of temperatures but at extreme cold (below -25°C) it can become stiffer. Reduction in flexibility can affect sealing performance, especially when used in areas where movement and adaptability are required. In very cold conditions, you run the risk that loss in seal quality will increase. When used in places where temperatures are regularly below -25°C, alternative materials such as FKM or silicone are recommended. Nevertheless, HNBR remains a durable solution in most industries.

Not Suitable for Dynamic Applications

Although the HNBR O-Ring 80 Shore A is suitable for static sealing where it can withstand high pressure and chemical stresses for long periods of time, it is less flexible and may deteriorate faster with constant movement or friction. This is due to its high shore hardness of 80. So it is less suitable for dynamic applications such as rotary seals. When you need a seal that moves a lot, softer materials such as NBR or FKM are recommended.
