Product Information
Full details
This 200-piece copper crush washer set by KDMD is an essential toolkit addition for mechanics, automotive enthusiasts, and industrial technicians who require reliable, high-pressure seals for fluid systems. Designed for use with sump plugs, fuel lines, and hydraulic fittings, these washers provide a durable, heat-resistant seal across a wide range of machinery; however, because they are made of copper, they are intended for single-use applications as they deform during tightening to create their seal.

FAQs
Can I reuse these copper washers?
No. These are designed as 'crush' washers, meaning they deform during the initial installation to create a seal. Once removed, they should be replaced with a new one.
Are these suitable for high-pressure hydraulic lines?
Yes, their material properties make them ideal for hydraulic fittings where a high-pressure seal is required.
Do I need to apply any sealant to these washers?
No, these washers are designed to create a seal on their own through compression. Adding chemical sealants is generally unnecessary and may interfere with the seal.
What is the melting point of these washers?
These copper washers have a melting point of up to 1083 Celsius.
Will these work on a marine engine?
Yes, they are highly effective for marine engine applications, including sump plugs and fluid cooling lines.
Troubleshooting
Oil or fluid continues to leak after installation
Verify that the mating surfaces are clean of debris, old gasket material, and oil. Ensure the correct size washer was used and that the bolt was torqued to the correct specification.
Washer deforms unevenly during tightening
Ensure the bolt is threaded squarely into the hole. If the bolt is angled, the pressure will be uneven, preventing a proper seal.
Pros and Cons
Pros
- Extensive 200-piece variety covers most standard fitting sizes
- High melting point ensures integrity in extreme engine heat
- Copper material creates a reliable seal that prevents fluid leaks
- Suitable for a wide range of automotive and marine machinery
Cons
- Copper washers are intended for one-time use only
- Requires proper torque during installation to avoid damaging the fitting
- Not suitable for applications requiring non-reactive materials in specific chemical environments
Setup, Compatibility & Care
To ensure a successful seal, always choose a washer that matches the diameter of your bolt or fitting precisely. When installing, place the new washer on the bolt and tighten to the manufacturer's specified torque settings. Avoid overtightening, which can cause the copper to deform excessively or strip threads.
Storage is equally important; keep the washers in a cool, dry place within their organizer to prevent oxidation. Although copper is corrosion-resistant, environmental moisture can cause surface tarnishing over long periods. Always discard used washers after removal, as the crushing process permanently alters their structure, making them unreliable for a second installation.
