Mbsomnus Copper Washers M12x18 mm Sump Plug Washer 20 Pieces Copper Sealing Rings Flat Sump Plug Gasket Crush Washer Metric Flat Gasket Rings for Fuel Accessories Oil Line Connection

• Package Contents: You will receive 20 Pieces Mbsomnus M12 copper washers. Mbsomnus sump plug washer measured approximately 12mm in inner diameter, 18mm in outer diameter, and 1.5mm in thickness. This ample quantity caters to diverse assembly and routine maintenance requirements. We also offer multiple specifications to facilitate selection according to your specific needs.
• Premium Material: Mbsomnus copper washers assorted are crafted from phosphor bronze, offering excellent ductility and corrosion resistance whilst maintaining stable performance in humid and high-temperature environments. Mbsomnus m12 washers copper exhibit high thermal conductivity. When compressed, they form extensive contact with metal surfaces, rapidly dissipating heat from contact points whilst minimising contact resistance.
• Reliable Connection: Mbsomnus copper m12 washers distribute the preload force between bolts and nuts, providing a larger bearing surface to prevent the nut or bolt head from tearing the fastened material. The damping properties of Mbsomnus crush washer partially absorb mechanical vibration energy, reducing the risk of bolt loosening.
• Effective Sealing: Mbsomnus Copper Sealing Rings undergo plastic deformation when subjected to bolt pressure, filling irregularities on the contact surface to form a tight fit. This prevents gas or liquid leakage while simultaneously generating frictional resistance between the Flat Washers m12 and threads through plastic deformation. This reduces friction between fasteners and prevents loosening.
• Versatile Applications: Mbsomnus Sump Plug Gasket Crush Washer serves as seals for pumps, valves, cylinders, oil pipe fittings, compressors, condensers and similar components. They also function as thermal interface materials between power devices (such as IGBTs and CPU heat sinks) and their housings. Ideal for oil pan plugs, sump plugs, fuel and hydraulic fittings, Sealing Ring Washer further serve as essential auxiliary components during maintenance and assembly procedures.

Mbsomnus copper washers are available in multiple standard sizes, including M6, M8, M10, M12, M14, M16, M18, and M20. These offer flexible compatibility with screws, bolts, and nuts of varying diameters, catering to diverse assembly and maintenance requirements. Whether for industrial machinery or everyday applications, suitable models can be readily found for swift and convenient installation. Mbsomnus Flat Washers possess excellent electrical and thermal conductivity, effectively aiding equipment heat dissipation and reducing overheating risks, thereby ensuring stable operation of mechanical and electrical apparatus. These washers exhibit superior corrosion resistance, remaining rust-free and distortion-free even under demanding conditions such as humidity or high temperatures, enhancing overall operational efficiency. Mbsomnus Copper Washer Sealing Rings form a tight seal with connecting components such as bolts, filling surface irregularities to create a robust barrier. This effectively prevents gas and liquid leakage, ensuring reliable operation throughout equipment cycles. Widely applicable in the assembly and maintenance of diverse equipment including piping systems, water heaters, air conditioning units, automobiles, motorcycles, and marine vessels, Mbsomnus Flat Copper Sealing Washers serve as indispensable, high-quality auxiliary components in both industrial production and domestic repairs.
