500 Piece 1mm Cross Section Metric Buna-N 70 O-Ring Kit
This comprehensive 500-piece metric O-ring kit is designed for durability and performance, offering a wide range of O-rings with a 1mm cross section, ranging from 2.5mm to 20mm in ID. Made from high-quality 70 durometer Buna-N (Nitrile), these O-rings provide reliable sealing solutions in various applications.
Buna-N seals are resistant to mineral oil-based lubricants, greases, many hydraulic fluids, aliphatic hydrocarbons, silicone oils, and water up to 80°C, making them ideal for a broad range of uses. Whether you’re working with hydraulic systems, automotive maintenance, or general industrial equipment, this kit is an essential addition to your toolbox.
Each O-ring is precisely sized and organized in a sturdy plastic case for easy access and storage, ensuring you have the right size on hand when you need it.

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.

- General purpose sealing.
- Petroleum oils and fluids.
- Gasoline
