402.04.0004 SCANIA Hose, Air Brake Compressor Repair Kits

The 402.04.0004 hose is a vital component within the air brake compressor repair kit system, designed to maintain precise pneumatic flow and system pressure. This part plays a critical role in ensuring the efficient operation of the compressor assembly, providing the necessary durability to withstand constant pressure fluctuations in heavy commercial vehicle environments.

This product is an OE-equivalent part designed for SCANIA vehicles. Specifically, 402.04.0004 is the OE equivalent of the SCANIA 812854, 814351, and 815459 hoses used in heavy-duty truck systems. It is engineered to meet strict technical standards to ensure seamless integration with existing braking architectures.

Workshop technicians should prioritize regular inspection of the compressor hose connections during routine maintenance intervals to prevent air leaks or pressure drops. When replacing this component, ensure that all fittings are secure and that the hose is routed away from extreme heat sources or moving mechanical parts to maintain long-term reliability and system integrity.
