Product Questions & Answers

these are listed as copper washers but the material says steel, which one is it actually?

Question by: Donna H on Jun 12, 2025, 9:51 AM

Good catch on that contradiction. The product attributes list the material as steel, so that overrides the "copper" in the product name. The name appears to reflect the washer type or series designation rather than the actual material composition. What you're getting is a steel sealing washer built to metric specs.

So, these are steel and not actually copper? Just want to make sure before I order a bunch.

That's right. These sealing washers are made of high-quality steel, which provides durability and corrosion resistance for hydraulic applications. The product name refers to their use as a sealing washer, not the material itself.
