HERCULES METAL CLAD WIPER

Precisely, this metal clad wiper is engineered to prevent contamination from dust, dirt, and moisture, which helps protect your hydraulic systems from potential damage and extends the lifespan of hydraulic components.

Metal cladding gives the wiper a rigid outer shell that holds its shape under pressure and impact, which a plain rubber wiper just can't match in rough industrial conditions. The metal backing keeps the sealing lip positioned correctly against the cylinder rod even when there's side loading or vibration involved. For applications where dust, dirt, and moisture are a constant problem, that added structural support means the wiper stays effective a lot longer before you start seeing contamination work its way into the hydraulic system.
