HERCULES METAL CLAD WIPER RING

On hydraulic cylinders, it sits at the rod end and wipes the rod as it moves so dirt, dust, and moisture do not get pulled into the cylinder. That helps protect the other seals and supports better cylinder performance.

The metal cladding reinforces the wiper's structure so it holds its shape and keeps steady contact with the rod surface even under varying operating conditions. A plain rubber wiper can flex or distort over time, which lets it lose that consistent contact. The metal backing keeps things tight and stable, which is what you need when you're trying to stop dirt, dust, and moisture from sneaking past the rod end and into the cylinder.
