Product Overview
Wiper seals keep contamination out of hydraulic cylinders and are a high-wear component in construction machinery, injection molding equipment and industrial hydraulics. The specialists listed here machine or mold DZ, DH, J and AD profiles per ISO 6195 from polyurethane 90–95 Shore A or PTFE-bronze compounds, covering rod diameters from 12 to 400 mm. Sharp wiping lips and correctly matched interference fit are inspected per batch to prevent oil film scraping or ingress. Suppliers serve cylinder repair shops and OEM hydraulics makers with both catalog sizes and per-drawing production, and material certificates accompany each shipment. Production lead time is typically 15–25 days for catalog sizes and 25–35 days for custom tooling programs.
