This 240PSI marine exhaust hose complies with USCG certification and the SAE J1527 B2 industry standard. Manufactured from specialized high-temperature and seawater corrosion-resistant rubber, it can withstand high-temperature engine exhaust gases without softening or damage. The multi-layer textile reinforcement structure ensures stable pressure containment at 240PSI, offering excellent vibration resistance and durability against stretching and deformation caused by vessel movement. The outer cover is highly resistant to salt spray and ozone aging, preventing cracking or delamination even during long-term immersion in marine saltwater environments. Highly flexible for easy installation and routing in confined shipboard spaces, it is professionally designed for exhaust emission systems of various marine engines.
