Mechanics and DIYers, these copper crush washers are essential for creating perfect seals in high-pressure and high-temperature applications. You get 24 pieces of 16x20x2mm washers that fit M16 fittings perfectly. The copper material provides a tighter seal and much better heat endurance compared to steel or rubber washers - they can handle temperatures up to 350°C and pressures up to 16MPa! The melting point is 1083°C, so these are seriously heat-resistant. They're widely used in automotive braking systems, chemical plants, power stations, and various industrial applications. The copper construction means they deform slightly under pressure to create a perfect, leak-proof seal. Each washer has an inner diameter of 16mm (0.63 inches), outer diameter of 20mm (0.79 inches), and thickness of 2mm (0.08 inches). The 24-piece pack means you have plenty for multiple projects or replacements. They work great for sealing high-pressure braking systems, air pumps, water pumps, valves, cylinders, and precision instruments. The copper tone looks professional, and the quality is consistent across all washers in the pack. Whether you're working on automotive repairs, industrial equipment, or precision machinery, having these quality copper crush washers on hand ensures you can create reliable, leak-proof seals that withstand extreme conditions. They're one of those small components that make a huge difference in the reliability and safety of your mechanical projects.
