Media capabilities
Standard materials are suitable for use with most mineral-based hydraulic fluids, and most fire-resistant fluids of the water/ oil or water/glycol types at temperatures up to 100°C (212°F). Also resistant to air, water and most lubricating oils and greases. Where fire-resistant fluids are used, it is essential to advise our Technical Support Team of the type and designation due to the effects that can occur with different grades.
Special materials considerably extend the range of application in terms of temperature, fluid compatibility and abrasion resistance. Please ask our Technical Support Team for further information.
