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.

In addition to preventing leaks, oil seals also protect the system from contamination by external particles like dust and debris. They act as a shield, stopping foreign elements from entering the hydraulic system and potentially causing wear and tear or blockages They act as a shield, stopping foreign elements from entering the hydraulic system and potentially causing wear and tear or blockages

The 90% part signifies the sealing effectiveness. An ideal oil seal should ideally prevent 90% or more of the lubricant from escaping, while also preventing contaminants from entering the system. Advanced designs, such as labyrinth seals or double lip seals, enhance this percentage by creating multiple barriers, improving the seal's ability to protect the internal components from damage Advanced designs, such as labyrinth seals or double lip seals, enhance this percentage by creating multiple barriers, improving the seal's ability to protect the internal components from damage

The concentration of HPMC in water also affects its solubility
hpmc solubility in water. As the concentration of the polymer increases, the viscosity of the solution also increases, making it more difficult for the polymer molecules to dissolve. However, at very low concentrations, HPMC may not dissolve completely, resulting in a colloidal suspension.

In addition to pH, the temperature of the solution also plays a significant role in the solubility of HEC

hydroxyethyl cellulose solubility. HEC is soluble in both cold and hot water, with solubility increasing as the temperature of the solution increases. However, care must be taken not to exceed the maximum temperature at which HEC can dissolve, as excessive heat can cause the polymer to degrade and lose its effectiveness.
