Tag: HBY buffer seal

What is an HBY buffer seal? HBY buffer seal is a specialized hydraulic buffer ring designed to protect primary rod seals from pressure spikes, heat, and excessive wear in heavy-duty hydraulic systems. As a critical component for cylinder longevity, it solves common pain points like seal failure, leakage, and premature downtime—making it indispensable for excavators, loaders, and industrial hydraulic machinery.
