50 PCS Nitrile Rubber O Ring 5mm OD 2mm ID 1.5mm Width, Metric Buna-N NBR Sealing Gasket Plumbing, Gas, Automotive and Faucet Repair, Resist Oil and Heat O-Rings, Black

The product is an O-Ring Assortment Kit that includes 15 different sizes of high-quality rubber O-Rings, suitable for various applications such as oil and gas, automotive, aerospace, and industrial manufacturing.

The kit features Nitrile Rubber, Silicone Rubber, and Fluororubber options, each with their own unique properties and advantages. Nitrile Rubber O-Rings offer excellent oil resistance, heat resistance, wear resistance, solvent resistance, and high pressure oil resistance, making them ideal for applications where exposure to harsh chemicals or high pressures is a concern.

They are also good for general purpose applications such as sealing and gaskets. Silicone Rubber O-Rings provide excellent elasticity, heat resistance, cold resistance, ozone resistance, aging resistance, and good insulation properties, making them suitable for applications where high temperatures or extreme weather conditions are present.

They also have good tensile strength and wear resistance, but may not be the best choice for applications that require high pressure resistance. Fluororubber O-Rings offer excellent weather resistance, ozone resistance, chemical resistance, and resistance to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils.

They are not recommended for ketones or low molecular weight lipids, but they provide good cold resistance and are suitable for applications where high temperatures or extreme weather conditions are present. The O-Ring Assortment Kit includes 15 sizes of O-Rings, ranging from 11*8*1.5mm to 6.5*3.5*1.5mm, and is made of high-quality materials such as Nitrile Rubber, Silicone Rubber, and Fluororubber.

The kit also includes a ratcheting combination wrench for easy installation. Overall, this O-Ring Assortment Kit offers a comprehensive solution for various applications that require high-quality rubber O-Rings.

With its diverse range of sizes, materials, and properties, it is an essential tool for any industry or individual looking to ensure the proper sealing and gasketing of their equipment or machinery
