Copper Washer Assortment Set, HELIFOUNER 300 Pieces 12 Sizes Copper Metric Sealing Washers Kit

I'm not sure if these are "true" copper, they seem a little hard. That said, so far, they have worked great for my needs!

If you work on your vehicle, always handy to have for brake lines and fuel lines. I replaced my fuel injectors and the kit did not come with new washers. I was able to find the ones I needed in this set.Same thing happened when changing calipers. One box did not have the compression washers. Again, having this set around solved the issues.

Great assortment. Quality seems good. I used on a 2000 Jetta (MK4) when replacing the power steering rack. I didn't replace the lines so I didn't have replacement washers when reattaching them. These worked great!

What can I say? They're copper crush washers. They worked for my application and I was able to find some in the kit that fit perfectly.

These copper crush washers are perfect for their intended use

Very inexpensive set of. Copper washers. A lot cheaper than the auto parts store

I needed these to finish a power steering rack and was glad I ordered this. Had every size I needed and more. These will come in handy I am sure. Washers seem high quality and seem to work well.

I have been using these to seal hydraulic lines on my John Deere tractor and they work great. I have also shared some with my friend to seal water lines. So great to have so many different sizes on hand for such a low price and such a compact package. I have saved money compared to the John Deere price after i used the first 3 washers.
