Copper Washers AWTools AW18307 — 95 pieces, flared/annealed type

Set of 95 copper washers AWTools AW18307 intended for sealing and ensuring conductive or pressure-tight connections in a range of mechanical and fluid systems. These flared/annealed copper crush washers are manufactured to be soft and malleable, allowing them to conform to irregular mating surfaces on fittings, bolts and banjo connections. The set contains multiple sizes suitable for common automotive, plumbing and hydraulic repair or maintenance operations where copper sealing rings are specified.

Advantages

Copper construction provides good thermal and electrical conductivity while remaining ductile enough to form a reliable seal under compression. The annealed, flared design improves contact area and adapts to surface imperfections, reducing the risk of leaks at joints exposed to pressure or vibration. Supplied as a comprehensive set of 95 pieces, the pack gives a range of sizes for different thread diameters and connection types, reducing the need for multiple separate purchases.

Suitable for

• Automotive brake and fuel banjo fittings
• Hydraulic system connections and adapters
• Plumbing joints where metal crush washers are required
• General maintenance and repair tasks requiring reliable metallic seals

Key specifications

• Material: annealed copper
• Type: flared / crush (malleable sealing washer)
• Pack quantity: 95 pieces
• Intended use: sealing and conductive connections for fittings, bolts and banjo joints
• Compatibility: suitable for hydraulic, automotive and plumbing applications where copper washers are specified

How to use

Select the washer size that matches the fitting or bolt diameter and place the copper washer between the mating surfaces, ensuring the flared side (if applicable) aligns with the sealing face. Tighten the fastener or banjo bolt to the manufacturer’s specified torque so that the washer deforms and forms a metal-to-metal seal. After installation, inspect the joint for any signs of leakage and retighten to specified torque only if recommended by the equipment manufacturer.

Usage recommendations

Use new copper washers for each sealing operation rather than reusing compressed washers. For critical systems such as brake or high-pressure hydraulic lines, follow vehicle or equipment manufacturer torque and replacement guidance and inspect connections after initial operation. Store the washers in a dry environment to prevent surface oxidation before use.
