The design of hub dust seals varies depending on the application and environmental conditions
hub dust seal. Some seals incorporate metal inserts for added strength and durability, while others may have unique compounds to withstand extreme temperatures or resist chemical corrosion. It's crucial to choose the right type of seal for each specific application to ensure maximum effectiveness.

The primary seal, often made of polyurethane, rubber, or PTFE (Teflon), prevents fluid from leaking past the piston. The secondary seal, typically an O-ring, provides additional security against fluid bypass. Wear rings, usually made of hard materials like bronze or steel, reduce friction and prevent scoring of the cylinder wall.
