Nylon breathable joints have various uses in automobiles, mainly related to ventilation and pressure reduction. Here are some common applications:

Fuel tank ventilation:

Nylon breathable joints are used to maintain proper ventilation of car fuel tanks, preventing tank deformation or fuel leakage caused by pressure changes.

Engine system ventilation:

Use nylon breathable joints in the engine hood and crankcase to maintain internal pressure balance and prevent component damage caused by excessive buildup.

Transmission ventilation:

Help balance the internal pressure and dissipate heat of the transmission, protect the seals, and improve the service life of the transmission.

Ventilation of braking system:

In some advanced braking systems, nylon breathable joints can be used to ensure normal system pressure, prevent brake fluid leakage or air from entering the system.

Exhaust Gas Recirculation (EGR) System:

In EGR systems, ventilation joints can be used to ensure proper flow of exhaust gases, helping to reduce emissions and improve fuel efficiency.

These uses are mainly achieved by providing ventilation solutions to maintain pressure balance within various systems, thereby optimizing automotive performance and extending the lifespan of critical components.
