💡 What makes cast polyurethane seals better than rubber for hydraulic systems?
The compound brings way tougher wear performance and higher stretch limits than soft rubber options.
- The dense polymer handles high pressure shocks without permanent deformation or extrusion gaps
- Petroleum fluid compatibility prevents swelling while maintaining tight tolerances on moving pistons
- Abrasion resistance extends equipment lifespan across continuous heavy duty cycling sessions
