All of the O-Rings listed here on Bath & Spa Parts Online are manufactured from various sources. All are made from Buna-N material, commonly known as Nitrile rubber, Perbunan, acrylonitrile butadiene rubber, and NBR. It is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Trade names include Nipol, Krynac and Europrene. The material is made to last under the most extreme conditions. If you have any questions about our o-rings, please feel free to contact our Customer Support Department for more information. Give us a call at 800-918-9143.

WHY USE BUNA-N (NUTRILE RUBBER)?

|
Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene). Although its physical and chemical properties vary depending on the polymers composition of nitrile, this form of synthetic rubber is unusual in being generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).
Bath & Spa Superstore carries a complete line of Buna-N Nutrile rubber o-rings, readily available for immediate delivery. We also adhere to the AS568 standard set forth for o-rings within their industry. Each individual o-ring will have all available information such as inside diameter (ID), outside diameter (OD), and cross section (CS), along with the AS568 number that corresponds with the product. All other o-rings will be custom o-rings for any given application and will have any information provided by the manufacturer.
