Find the right size, compare compatible materials, and choose the best cross section shape for your O-ring.
Oil-Resistant Buna-N O-Ring Assortments

All of the O-rings in these assortments are made of Buna-N. They resist animal, vegetable, and motor oils. All have a round profile and are suitable for a wide range of static and dynamic sealing applications.
Inch O-rings have a dash number and are sized to the SAE standard AS568.

Weather- and Oil-Resistant HNBR O-Ring Assortments


Keep a variety of sizes handy so that you always have the O-ring you need. The HNBR O-rings in these assortments are a step up from Buna-N O-rings—they contain extra hydrogen to better resist chemicals, weather, and abrasion. They won’t swell from contact with grease and acid, making them a good choice in engine, hydraulic, and HVAC systems. Because they won’t deteriorate from ozone, UV, or oxidation, these O-rings are also good for outdoor use. However, they won’t withstand solvents or strong acids like Viton® fluoroelastomer O-rings do. They’re also known as hydrogenated nitrile and highly saturated nitrile O-rings.
