Ultraflex Hydraulic Steering Hose Kit 9m

Ultraflex hydraulic steering hoses (SKU 40847P, EAN 8031164408472) are factory-assembled, two-line flexible hoses designed for hydraulic steering systems of boats and yachts with a hand pump (helm pump) and Ultraflex rudder actuator. Applications include both single-direction installations in small units with outboard engines and more complex systems with distributors, autopilots, or additional control stations, provided they fit within the allowable pressure and are compatible with ISO VG 15/32 class hydraulic oil. The hoses are terminated with straight fittings with 1/4"-NPT tapered thread (typical for Ultraflex systems), allowing quick assembly without crimping the ends; connections are sealed with PTFE tape or appropriate NPT thread paste. Each set includes a pair of hoses (PORT and STBD) with an outer cover resistant to UV radiation, saltwater, and abrasion, with a factory-installed vent/transport cap. The hoses are color-coded/marked for easy direction identification. Installation should be done with gentle bends, maintaining minimum bend radius and avoiding twisting; the route should be secured with glands and clamps every 30–50 cm. The product is part of systems compliant with the Recreational Craft Directive (RCD) and ABYC/ISO standards for steering systems; it works with Ultraflex UP series pumps and UC actuators. Dedicated for replacement/extension of OEM installations in motorboats and RIBs where reliability, tightness, and marine environment resistance are critical.
