One of our most usable O-Ring kits. Buna-N O-Rings are the most common and the simplest types of seal with an excellent sealing property and durability. Recommended for use with crude oil, gasoline, propane, petroleum oils and water. It is used in engines, gearboxes and also can be found in anything from shower heads, garden hoses, pumps up to an aircraft. Nitrile O-Rings are used as a face to face gasket style seal or as a shaft seal, and allow both rotary and linear movement.

This kit contains a total of 382 O-Rings in 30 different sizes, providing an extremely low cost per size value.

Buna-N O-Rings 70 Duro (NBR):

The most commonly used elastomer for sealing products. Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum base oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties. The material performs well with most dilute acids, silicone oils and lubricants and in water applications. It is not recommended for use with ketones, aromatic hydrocarbons and phosphate ester hydraulic fluids. More than 50% of the O-Rings sold are Nitrile O-Rings, commonly used in hydraulic/pneumatic motors, cylinders, pumps and valves.
