This 25ft flexible rubber brake hose is engineered to meet DOT standards for hydraulic trailer brake systems. Ideal for boat trailers, it efficiently routes brake fluid from the master cylinder or surge coupler along the frame to the first braked axle. Designed for high-pressure applications, this hose is compatible with both drum and disc brakes, including setups using surge couplers or electric-over-hydraulic units. Its UV-resistant construction ensures long-lasting durability in harsh marine environments by resisting sun and saltwater degradation. The hose features robust brass 3/16-inch male inverted flare fittings with a standard 3/8"-24 thread, ensuring a secure, leak-free connection with most trailer brake components such as calipers, wheel cylinders, master cylinders, and solenoid valves. The swivel fittings prevent twisting during installation, providing reliable performance even under extreme conditions.
