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

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!

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.

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.

I recommend

These copper crush washers are perfect for their intended use
