Material
Hydrogenated Nitrile Butadiene (HNBR), also known as Highly Saturated Nitrile (HSN) is a special class of nitrile rubber (NBR) .O-rings are the most commonly used elastomers for sealing products .Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum base oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties.
Temperature
HNBR can be formulated to meet the application temperatures ranging from -45 ° C to 165 ° C, and HNBR is classified by ASTM as DH-type polymer.
Features
Available for professional use and also suitable for home use.
Strong sealing and durable.
UV resistant, suitable for liquids such as oil.
Our o rings are made from commercial grade nitrile butadiene rubber (NBR) formulation that provides great resistance to oils.
Application
Great for Home and Professional Use
Thick Walled Construction
Say good bye to leaks. The UV resistant material works great with liquids such as oil and extra thick wall construction provides maximum protection while maintaining long term durability.
