[Hot Item] 21ft Boat Trailer Brake Hose with Male Inverted Flare Fittings

This 21ft flexible rubber brake hose is engineered to meet DOT standards for hydraulic trailer brake systems. Primarily used on boat trailers, it can also serve any trailer equipped with hydraulic brakes. Typically, it runs from the master cylinder or surge coupler along the frame to the first axle brake assembly. Rated for high-pressure applications, this hose works with both drum and disc brakes, including those using surge couplers or electric-over-hydraulic units. Its UV-rated construction protects against sun and saltwater deterioration, ensuring long-lasting performance in harsh marine environments. The hose is fitted with durable brass 3/16-inch male inverted flare fittings, featuring a standard 3/8"-24 thread for a secure, leak-free connection with most trailer brake components such as calipers, wheel cylinders, master cylinders, and solenoid valves. The swivel design of the fittings prevents twisting during installation for optimal performance.
