6,000 mm Stainless Steel Brake Line Kit – Tandem Axle | SAE J1401 / DOT Certified

Overview

The BLK.6000T is a comprehensive brake hose system designed for tandem‑axle trailers up to approximately 7 m. It includes braided stainless steel hoses with PTFE (Teflon®) inner cores, all pre-flared with 3/8″ UNF fittings for hassle-free installation. The kit also features three brass 3‑way joiners for clean branch routing.

Fully certified to SAE J1401 and U.S. DOT standards, this kit ensures compliant hydraulic braking for caravans, RVs, boat trailers, and other heavy-duty trailer applications.

⚙️ Technical Specifications

🚚 Best Use Cases

Perfect for:

• Tandem-axle trailers (7 m or shorter chassis) with hydraulic drum or disc brakes

• Boat, caravan, and RV applications where flexible hose routing is essential

• Environments prone to corrosion or moisture

• Projects wanting quick installation with no brake tubing tools

🔍 Why Choose This Kit?

Compared to traditional copper or rubber lines, stainless braided hoses with PTFE inner cores provide superior durability, reduced expansion, and sharper brake response. This complete kit—with multiple fixed lengths and joiners—cuts setup time dramatically while offering full DOT/SAE compliance. 

🛠 Installation Suggestions

1. Secure hoses along chassis rails or “I” beams using stainless P‑clips.

2. Maintain smooth, sweeping curves—avoid tight bends over suspension components.

3. Hand‑tighten flare fittings prior to final torque to prevent hose twisting.

4. Thoroughly bleed the brake system post-installation to eliminate air pockets.
