What Are Copper Washers?
A copper washer is a flat washer manufactured from copper and installed beneath a fastener, fitting or connection point.
Copper washers are frequently used because they can:
- Create a reliable seal
- Distribute loads
- Prevent surface damage
- Absorb vibration
- Resist corrosion
- Accommodate thermal expansion
Their softness and compressibility make them particularly effective in sealing applications where small surface imperfections need to be accommodated.
Why Use Copper Washers?
Copper offers several unique advantages compared with other washer materials.
Excellent Sealing Performance
Copper washers deform slightly under compression, helping to create an effective seal between mating surfaces.
Corrosion Resistance
Copper performs well in many industrial and environmental conditions.
Thermal Conductivity
Copper transfers heat efficiently, making it suitable for high-temperature applications.
Malleability
Copper is softer than many engineering metals, allowing it to conform to irregular surfaces.
Long Service Life
Properly specified copper washers can provide reliable long-term performance.

Annealed Copper Washers
Some applications require annealed copper washers.
Annealing softens the copper and improves its ability to deform under compression.
Benefits include:
- Improved sealing performance
- Better conformity to mating surfaces
- Reduced risk of leakage
- Greater compression recovery
Annealed copper washers are frequently used in hydraulic, fuel and fluid sealing applications.

Frequently Asked Questions
What are copper washers used for?
Copper washers are used for sealing, spacing, load distribution and vibration reduction. They are commonly found in hydraulic systems, fuel systems, plumbing installations and industrial equipment.
Why are copper washers used for sealing?
Copper is soft and malleable, allowing it to deform slightly under compression and create an effective seal between mating surfaces.
What is a copper crush washer?
A copper crush washer is designed to deform when tightened, helping create a leak-resistant seal in hydraulic, fuel and fluid systems.
Are copper washers reusable?
Copper washers are generally not recommended for repeated reuse because compression can permanently alter their shape and sealing performance.
What is an annealed copper washer?
An annealed copper washer has been heat treated to soften the material, improving its sealing capability and ability to conform to mating surfaces.
