About O-Rings

Find the right size, compare compatible materials, and choose the best cross section shape for your O-ring.

Oil-Resistant Buna-N O-Rings

Made of Buna-N, these O-rings resist grease, hydraulic oil, and motor oil—plus mild chemicals and water. However, Buna-N is not for use with brake fluid. These O-rings are commonly used to create multidirectional seals between two parts in power transmission assemblies, hydraulic cylinders, and pneumatic cylinders. They resist compression and tearing to keep their shape over time. All have shelf life, a cure date, and a traceable lot number printed on the package.

Oil-Resistant Buna-N O-Ring Assortments


380, 436, and 500 Pieces	382 and 385 Pieces

With a range of sizes on hand, you’ll always have the right O-ring for the job. Made of Buna-N, the O-rings in these assortments resist grease, hydraulic oil, and motor oil. They also withstand mild chemicals and water, although they’ll break down from exposure to brake fluid. Their resistance to compression and tearing helps them keep their shape over time, so they’re often used to seal power transmission assemblies and pneumatic cylinders.

FDA-Compliant Oil-Resistant Buna-N O-Rings

FDA compliant for direct contact with food, these Buna-N O-rings create a strong seal in food and beverage lines. They won’t weaken from animal and vegetable oil, citric acid, sodium bicarbonate, and other substances used in food processing. They also resist tearing when used in moving equipment, so you can count on them for durability. All have shelf life, cure date, and a traceable lot number printed on the bag.

Oil-Resistant Soft Buna-N O-Ring Assortments

400 Pieces

Keep a variety of sizes on hand so that you always have the O-ring you need. The O-rings in these assortments are softer than standard Buna-N O-rings, so they form a better seal in low-pressure applications. They offer the same level of oil resistance, so they’re often used on oil drain plugs or hydraulic return lines.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Water- and Steam-Resistant EPDM O-Ring Assortments

400 Pieces

Stock a range of sizes so you always have the O-ring you need. Made of EPDM, the O-rings in these assortments have excellent resistance to water, steam, and glycol-based fluids, including brake fluid. They’re often used to seal plumbing and refrigeration systems, since they won’t swell or break down in moist environments.
