Trident Marine 4' Black Stern Flex Hose w/Transom Flange

The Trident Marine 4' Black Stern Flex Hose with Transom Flange is a purpose-built conduit system for routing wiring, control cables, and hydraulic hoses between a vessel's transom and outboard engine. Part of Trident Marine's proven 129 series, this 4-foot black hose assembly connects directly to Trident flange part #142-2000, providing a sealed, flexible pathway that withstands the demanding marine environment where salt air, UV exposure, fuel spray, and constant engine vibration challenge standard hose materials.

The hose features exceptional resistance to crushing and abrasion, critical properties where hoses route under gunwales or near engine manifolds. Chemical resistance protects against fuel, oil, and coolant contact, while the reinforced construction maintains flexibility even in cold water conditions—a key advantage over rigid conduit that can crack or become brittle. The black finish resists UV degradation, extending service life in harsh saltwater and freshwater applications. At 2 lbs and compact in diameter, the hose integrates cleanly into modern outboard installations without adding substantial weight or bulk.

This stern flex hose serves weekend boaters performing routine outboard maintenance and serious offshore anglers operating in exposed waters where reliability is non-negotiable. Whether you're replacing a damaged cable conduit, upgrading from aging PVC tubing, or building a custom engine installation, this Trident hose assembly delivers the durability and flexibility that modern marine systems require. Compatibility with Trident's flange system ensures a secure, watertight connection that isolates internal cables from external elements.
