5,500 mm Stainless Steel Brake Line Kit – Tandem Axle Trailer | DOT/SAE Certified

Overview

This 5,500 mm Stainless Steel Brake Line Kit (BLK.5500T) is a full hydraulic brake hose solution for tandem‑axle trailers up to approximately 7 m long. Featuring braided stainless steel hoses with PTFE (Teflon®) inner cores, this kit includes pre‑flared 3/8″ UNF fittings and brass 3‑way joiners—no flaring tools needed. Engineered for clean interiors and flexible routing, this kit is certified to SAE J1401 and U.S. DOT standards and suitable for caravans, boat trailers, campers, and RV builds.

⚙️ Technical Specifications

🚚 Ideal Applications

• Tandem-axle trailers used for caravans, RVs, boats, or campers (approx. 7 m chassis length)

• Brake systems that require easy, flexible routing without rigid steel tubing

• Coastal or high-damp environments demanding corrosion-resistant hardware

🔍 Why Choose This Kit?

Compared to traditional copper or rubber brake hoses, stainless braided hoses with PTFE cores deliver firmer pedal response, less expansion under pressure, and greater flexibility for clean chassis routing. The complete kit—with multiple hose lengths and joiners—reduces install time and tools required, while maintaining full DOT/SAE brake compliance. 

🛠 Installation Tips

• Secure hoses along the chassis using stainless steel P-clips to prevent wear

• Maintain smooth curves; avoid tight bends near suspension or pivot points

• Always hand-tighten fittings before torqueing to avoid damage

• Bleed the brake lines thoroughly after installation to remove air
