DuraLink™ DOT Air Brake Tubing Copy

DuraLink™ DOT tubing is Alkon’s high-performance nylon tubing, engineered for demanding air brake and air suspension systems. Made in the U.S., it is DOT-compliant and meets the Federal Motor Vehicle Safety Standard (FMVSS) 49 CFR 571.106 and the Society of Automotive Engineers (SAE) J844.

Part of the DuraLink™ Solution, it provides secure, leak-resistant connections for both new builds and repairs. Its construction withstands vibration, pressure changes, and extreme temperatures, delivering consistent operation in demanding conditions.

Alkon DuraLink™ DOT tubing undergoes rigorous in-house testing to meet SAE J844 and FMVSS 49 CFR 571.106 standards. These tests simulate real-world air brake and air suspension conditions, ensuring leak-free, durable, and safe connections.
Key performance highlights:

• Tensile Strength: Nearly 2x the SAE peak load requirement
• Elongation: 3x the required elongation
• Bend Performance: Maintains integrity at tight bend radii
• Operating Temperature: Performs reliably from -40°F to +200°F

These results give fleets and OEMs confidence that DuraLink™ tubing will perform reliably in every installation.

Alkon DuraLink™ DOT tubing consistently outperforms U.S. and imported alternatives:

• Elongation: Competitor fittings and tubing achieve only 20% of DuraLink™’s elongation
• Tensile Strength: Many import fittings and tubing fall up to 40% below Alkon standards
• Bend Integrity: While competitor tubes may fail under tight bends, DuraLink™ retains its shape and function

These performance advantages reduce maintenance and downtime, making DuraLink™ a reliable choice for DOT-compliant air brake and suspension systems.

Yes. DuraLink™ tubing is compatible with other manufacturers’ fittings and can improve their performance. Internal testing shows that pairing competitor fittings with DuraLink™ tubing delivers:

• Up to 145% increase in elongation
• Up to 43% increase in tensile strength

For the best overall performance, use the full DuraLink™ Solution. Combining DuraLink™ DOT tubing with Alkon push-to-connect fittings delivers unmatched system durability and DOT compliance.

Air brake systems rely on both tubing and fittings. Even the best fittings cannot compensate for inadequate tubing. Low-quality tubing can stretch, crack, or pull out under pressure, resulting in air leaks or system failure.

DOT-compliant tubing maintains consistent air pressure, safe braking, and long-term operation, protecting fleets from downtime, costly repairs, and safety risks. According to the Federal Motor Carrier Safety Administration (FMCSA), brake issues contribute to 45.5% of large truck crashes, highlighting why every component must perform reliably. 

DuraLink™ DOT tubing is available in multiple diameters and colors. It can be ordered in standard roll lengths or cut-to-length to meet the needs of new builds and repairs.

Choosing the complete Alkon DuraLink™ Solution ensures peace of mind in every connection and delivers high-performance air brake reliability that cannot be achieved by mixing components. 

The full solution works together to provide three key advantages for fleets and OEMs:

1. Proven System-Level Performance: Alkon’s in-house testing shows the DuraLink™ Solution delivers higher tensile strength, greater elongation, and improved overall durability than any mixed-component pairing.
2. North American Manufacturing: Producing both tubing and fittings in North America ensures consistent materials, controlled processes, and quality, supporting dependable lead times and a stable supply chain.
3. Compliance with SAE and FMVSS Standards: Every DuraLink™ Solution is engineered in accordance with SAE J844 and DOT FMVSS 49 CFR 571.106, giving fleets and OEMs confidence that it meets or exceeds all DOT requirements.
