Hydraulic applications create a demanding environment for sealing elements. High pressure inside the cylinder, constant motion and fluctuating temperatures require seal materials that are both flexible and wear-resistant. Choosing the wrong material may not show up immediately, but over time it leads to micro-leaks, pressure loss and eventually system failure.
A hydraulic seal's core job is preventing fluid leakage from the cylinder. To do this reliably, the material must match the operating temperature range, the chemical nature of the fluid used (mineral oil, water-based fluid, synthetic oil, etc.) and the system's pressure level. For example, fluorocarbon (Viton) based compounds are preferred where high temperature and chemical resistance are required, while natural rubber or nitrile-based materials may suit more standard conditions.
Verdi Plastik matches the seals and sealing elements it produces for hydraulic systems to the application's pressure and temperature conditions through material engineering.
