Polished Copper Washers, For Fittings, Automotive Industry, Feature : High Quality, Corrosion Resistance

Material: Copper washers are made from pure copper or copper alloys. Copper is chosen for its excellent thermal conductivity, corrosion resistance, and malleability, which allows for a good seal when compressed between mating surfaces.

Shape and Size: Copper washers typically have a flat, round shape. The size of a copper washer is specified by its inner diameter (ID), outer diameter (OD), and thickness. These dimensions are measured in millimeters (mm) or inches (in) and should be compatible with the mating surfaces.

Sealing Applications: Copper washers are commonly used in applications that involve sealing connections where fluids or gases are present, such as pipe fittings, hydraulic systems, fuel systems, and engine components. They are often used in conjunction with bolts or screws to create a tight seal.

Compression and Sealing: Copper washers work by being compressed between the mating surfaces, which deforms the washer and creates a seal. The soft and malleable nature of copper allows it to conform to irregularities and create a reliable seal.

Advantages: Copper washers offer several advantages, including good heat and electrical conductivity, resistance to corrosion, and excellent sealing properties. They can withstand high temperatures and are suitable for applications where a reliable and durable seal is required.
