The Hydraulic Power Hammer Piston U Cup Seal is designed to seal components used in hydraulic power hammers to maintain unit integrity and efficiency. This U-shaped seal fits around the piston, creating a tight barrier that prevents hydraulic fluid from leaking past the piston during operation. It maintains the correct pressure within the hydraulic system, the U Cup Seal enhances the power hammer's performance, reliability, and lifespan. Attributes:• Effectively seals under high hydraulic pressures.• Consistently provides a secure seal over long-term use.• Ensures zero leakage for optimal hydraulic performance.Applications: The Hydraulic Power Hammer Piston U Cup Seal is positioned within the hydraulic power hammer assembly, around the piston, where it creates a seal to prevent hydraulic fluid from leaking and to maintain the necessary pressure for effective operation.
