Product description

This specialized U-cup packing kit is optimized for Joyce 10-1/2 inch bore cylinders that require a ribbed-style seal. Unlike standard flat packings, the ribbed U-cup design provides multiple contact points to better handle minor surface imperfections on the ram. It is particularly effective for Joyce lifts where a standard packing might struggle to maintain a perfect seal under fluctuating pressures. The U-cup geometry utilizes hydraulic pressure to expand the seal against the cylinder wall, creating an increasingly tighter fit as the load increases. This kit is the preferred choice for technicians looking for a modern sealing solution for legacy Joyce equipment.

Product highlights

• Ribbed U-Cup Design: Features a multi-lip profile that improves sealing performance on older or slightly worn Joyce ram surfaces.
• Pressure-Activated Sealing: The U-cup shape naturally widens under load to provide a more secure barrier as lifting weight increases.
• 10-1/2 inch Bore Precision: Sized specifically for the internal dimensions of Joyce in-ground hydraulic cylinders.
• Friction Reduction: Engineered to slide smoothly against the ram, reducing heat buildup and wear during high-frequency lift cycles.
