Key benefits Provides a reliable seal and even load distribution between flange surfaces, helping to minimize leaks in bolted joints. Copper's malleability allows the washer to conform to minor surface irregularities, improving sealing performance. Thin 2 mm profile with an outer diameter of 30 mm and inner diameter of 24 mm suits compact assemblies while maintaining a solid sealing surface. Red copper (T3) material offers corrosion resistance in many environments and suitable mechanical properties for sealing gaskets. Pack includes 12 pieces, enabling easy replacement and stock for maintenance tasks. Key attributes Type: Copper flat washer with sealing gasket functionality Material: Red copper, T3 grade Inner diameter: 24 mm Outer diameter: 30 mm Thickness: 2 mm Compatibility: Designed for M24 fasteners and standard flange/sealing interfaces Quantity: 12 pieces per pack Specifications and performance The washer acts as both a loaddistributing flat washer and a seal gasket in one component. Made from red copper (T3), offering malleability for forming a tight seal on flange faces. Fits M24 bolt applications with an inner bore of 24 mm, providing a precise and compatible seal surface. Applications and use cases Plumbing flange seals: use in pipe connections where a copper sealing washer is preferred to improve leak resistance. Hydraulic and pneumatic flange joints: suitable for sealing interfaces in systems using M24 fasteners. General mechanical assemblies: appropriate for applications requiring load distribution and a copper sealing ring in compact spaces.
