3. Size and Specifications The dimensions of the hydraulic cylinder oil seal play a crucial role in determining price. Custom-sized seals are often more expensive due to the added manufacturing requirements. Standard sizes typically benefit from economies of scale, driving down costs. Additionally, seals designed to meet specific pressure ratings or other performance criteria may incur higher costs due to the need for advanced materials and testing.
