Trident Hose 100-0784 Flex Wet Exhaust & Water Hose 7/8" ID x 12.5 ft Hardwall Black

The Trident Hose 100-0784 is a premium 7/8" inner diameter hardwall flex wet exhaust and water hose, supplied in a 12.5-foot length. Part of Trident Marine's trusted 100 Series, this hose is purpose-built for demanding marine environments where longer runs or angled connections are required. The distinctive black hose features a blue stripe for easy identification.

Constructed with a high-temperature EPDM (ethylene propylene diene monomer) rubber tube and cover, this hose withstands continuous operating temperatures up to 250°F and a maximum operating pressure of 57 PSI. An embedded wire helix sits between two tough synthetic spiral cord plies, giving the hose an extra-heavy wall that resists panting, collapse, and kinking — even in tight-radius installations.

Key Features:

• 7/8" inner diameter, 12.5 ft length hardwall construction
• High-temp EPDM rubber tube and cover rated to 250°F continuous operation
• Wire helix embedded between 2-ply synthetic spiral cord reinforcement
• Excellent flexibility and tight bend radius for complex routing
• Resists heat, ozone, exhaust gases, and sanitation chemicals
• Smooth interior surface minimizes engine back pressure
• Black with blue stripe for easy identification
• Meets or exceeds SAE J2006, ABYC, and NMMA standards
• 5-year warranty

At the 7/8" diameter, this hose is well suited for engine intake, bilge discharge, toilet and holding tank connections, and drain scupper lines. Installation requires a minimum of two stainless steel clamps at each end; 3/4" wide T-bolt clamps or 5/8" wide constant torque clamps are recommended for a secure, leak-free seal.
