products

Buna-N flange gaskets, sometimes called Nitrile flange gaskets or NBR flange gaskets, are resistant to oils, fuels, and greases – plus mild chemicals and water. Buna-N is a tough and durable material with good resistance to abrasion, compression, and tearing. It is a multipurpose material with broad ranging application coverage. Flange gaskets are used to seal ASME/ANSI pipe flanges.
