Protective hoses play an important role in vehicle air conditioning systems by protecting sensitive components of the air conditioning system, such as coolant hoses and electrical cables. These hoses resist mechanical damage, environmental influences and help maintain the integrity of components throughout the life of the vehicle. Protection tubes are usually made of durable plastic or metal, which offer excellent resistance to abrasion, impact and corrosion. Properly installed ducting increases the reliability and safety of the air conditioning system, reducing maintenance costs and extending the life of the system.
