The Seal Group @Gatlin Corporation offers a wide variety of Buna N (Nitrile,NBR,ACN) materials.

The NBR family often makes up what is known as "Black & Round".  What is key to know, the actual ACN content of Buna N O-rings varies considerably (18% - 50%) with world class manufacturers such as Parker.  The ACN content can vary even more with the "Black & Rounds" of the world.  A polymer with more ACN content exhibits less swell in gasoline and aromatic solvents, while lower ACN polymers exhibits better compression set and low temperature flexibility.

On this page you will find links to the material reports for some of the most common Buna N (Nitrile,NBR,ACN) we offer.  We have UL approved, AMS, FDA, NSF,general purpose, Fuel Resistant and others available.  If you don't see what you are looking for, please fill out our Contact US/RFQ and will get you the information you need.  Thank you for visiting our site!
