This 23ft flexible rubber brake hose is DOT approved and engineered for hydraulic trailer brake systems. It is ideal for boat trailers, efficiently running from the master cylinder or surge coupler along the frame to the first axle. Designed for high-pressure applications, it supports both drum and disc brakes, including setups with surge couplers or electric-over-hydraulic actuators. The UV-resistant rubber construction protects against sun and saltwater damage in harsh marine environments. The hose is fitted with durable brass 3/16-inch male inverted flare fittings using a standard 3/8"-24 thread, ensuring compatibility with most trailer brake components such as calipers, wheel cylinders, master cylinders, and solenoid valves. Swivel fittings help prevent twisting during installation, ensuring a secure, leak-free connection.
