The Trident Marine Vac Hose is a premium, extra-heavy-duty solution engineered specifically for the most demanding marine sanitation and bilge environments. With a 1 1/2" diameter, this black sanitation hose features a smooth bore interior to prevent clogging and minimize odors, while the rugged, reinforced exterior resists collapsing under high vacuum pressure. Its high-tensile construction is built to withstand extreme temperatures, vibrations, and the corrosive effects of saltwater and waste. Whether you are upgrading a head system or installing a high-capacity bilge pump, the Trident Marine Vac Hose provides the industrial-grade durability and "no-fail" reliability required for critical below-waterline applications.
