While EVs primarily rely on electric motors for propulsion, they still use hydraulic systems in various parts of the vehicle, which require hydraulic seals to maintain their functionality. Here are a few examples of where hydraulic seals are commonly used in EVs:

• Brake Systems: Many EVs use hydraulic brake systems, similar to traditional internal combustion engine vehicles. Hydraulic seals are used in the brake calipers and master cylinder to maintain hydraulic pressure and prevent fluid leakage.
• Suspension Systems: Some EVs have hydraulic suspension systems for improved ride comfort and handling. Hydraulic seals are used in these systems to prevent leaks and maintain pressure.
• Power Steering: Some electric vehicles have hydraulic power steering systems that assist with steering. Hydraulic seals are used in the power steering pump and other components to ensure that hydraulic fluid is contained within the system.
• Cooling Systems: Electric vehicle batteries and power electronics generate heat, and many EVs use hydraulic cooling systems to manage temperature. Hydraulic seals are used in these cooling systems to prevent leaks.
• Transmission and Drive Systems: Some EVs, especially hybrids, may have hydraulic components in their transmission or drive systems. Seals are used to prevent fluid breaches in these areas.

It's worth noting that the extent to which hydraulic systems are used in EVs can vary. Some EVs, especially those with fully electric powertrains, may have fewer hydraulic components than traditional vehicles, while others, like hybrid vehicles, may still rely on hydraulic systems to some degree. As technology evolves, the automotive industry is also exploring alternatives to hydraulic systems in favor of more energy-efficient and environmentally friendly solutions.
