✅ Hard durometer A90 handles extreme loads
✅ Works in hydraulic oil and light acid mixtures
✅ Cast polyurethane lasts longer than rubber

💡 What makes cast polyurethane handy for tough hydraulic mounts?

Polyurethane compounds stay firm when pumps kick in. Regular rubber swells or melts. - Oil proof cores handle pump friction daily - Hard durometers block slurry grinding - Low compression keeps gaps sealed tight - Acid resistant blends survive factory washdowns✝️
