This 19ft flexible rubber brake hose is DOT approved and engineered for hydraulic trailer brake systems. It is widely used on boat trailers to run from the master cylinder or surge coupler along the frame to the first braked axle, but it is also suitable for any trailer equipped with hydraulic brakes. Rated for high-pressure applications, this hose works seamlessly with both drum and disc brakes, including systems utilizing surge couplers or electric-over-hydraulic units. The UV-resistant rubber construction ensures long-lasting performance even under harsh marine conditions, protecting against sun and saltwater damage. It features durable brass 3/16-inch male inverted flare fittings with a standard 3/8"-24 thread, which are compatible with most trailer brake components such as calipers, wheel cylinders, master cylinders, and solenoid valves. The swivel fittings prevent twisting during installation, ensuring a secure, leak-free connection.
