Trident 1-1/4-Inch 50-Foot Flex Wet Exhaust Hose

The Trident Flex wet-exhaust hose is built to follow curved engine-room plumbing without relying on a series of short rigid sections. Its 1-1/4-inch inside diameter is used for compatible exhaust, engine intake, critical water, and drain connections. High-temperature black EPDM rubber, marked with a blue stripe, forms the tube and cover.

Multiple layers of high-tenacity polyester and a steel-wire helix reinforce the rubber so the hose resists collapse, vibration, and repeated flexing. Trident lists a 70 psi working-pressure rating and a tight 1.5-inch bend radius for this size. Trident rates the hose for service up to 250°F and cites SAE J2006-R2, ABYC/NMMA P-1, and Lloyd’s type approval. These standards matter for wet-exhaust service where ordinary water hose would be unsuitable.

The 50-foot coil is intended for cutting to the lengths required by a particular installation. Confirm the engine manufacturer’s required hose diameter, temperature capability, and clamping method before using it on an exhaust connection. A proper exhaust-hose installation must accommodate engine movement without allowing the hose to sag or kink. Find other fittings and hose options in our marine exhaust components range.
