4LIFETIMELINES 3/16" x 18" Rubber Brake Hose – 3/8-24 Male to Female Swivel Fitting | DOT Approved, SAE J1401 Compliant | Universal Trailer & Vehicle Brake Line Replacement

Upgrade Your Trailer Braking System with Confidence: When brake hoses age, they crack, swell, and create a spongy pedal feel that compromises stopping power — especially under heavy towing loads. The 4LIFETIMELINES 3/16" x 18" Universal Rubber Brake Hose is a direct bolt-on replacement designed to restore firm, responsive braking to your trailer, utility vehicle, or equipment. Built to Spec, Not to a Price Point:This hose features a 3/8-24 thread male-to-female swivel fitting that connects directly to standard brake line hardware. The heavy-duty rubber construction resists brake fluid, ozone, UV, and road salt — the four biggest enemies of brake hose longevity. DOT approved and SAE J1401 certified, it meets every federal requirement for highway use. Who Is This For?: If you're maintaining or rebuilding the hydraulic brake system on a boat trailer, utility trailer, car hauler, RV, or industrial cart, this hose delivers the quality and peace of mind that generic imports cannot.

The male-to-female swivel fitting ensures a secure, leak-free connection without adapter hassles. Ideal for boat trailers, utility trailers, car haulers, RVs, and industrial equipment.
