Buna-N nitrile O-Rings
Buna-N / Nitrile / nbr O-rings offer general purpose sealing
Buna o-rings, NBR or nitrile o-rings offer excellent sealing properties and good mechanical properties with low cost. Buna and Nitrile O-rings have a basic resistance to common lubricants, and is recommended for crude oil, gasoline, propane, petroleum oils and water. Nitrile and Buna O-rings are used in engines, gearboxes, aircraft pumps, and common water applications.
Nitrile Buna-N NBR O-Rings are used as a face to face or shaft seals, and allow rotary and linear movement. Good tear and abrasion resistance with Operating temperature: -30° to +250F° (can be increased special compounds).
Buna-N O-Ring Variations
Buna-N / Nitrile / NBR o-rings are available in many colors and durometers, and have a variety of compounds for specific applications.Durometers and Colors, as well as many compound variations designed to meet specific applications. Nitrile / Buna / NBR o-rings have limitations in ozone, sunlight and weathering.
Parker Buna-N, Nitrile o-rings are recommended for: Petroleum base oils and fluids, mineral oils, ethylene glycol base fluids, silicone and di-ester base lubricants, air, water under 150°F, and natural gas. Common Parker compounds for NBR, Buna, Nitrile o-rings are N0674 Black.
