Genuine Shacman X5000 Polyamide Tube SZ144000751 – OEM Pneumatic Tubing

Technical Specifications of Polyamide Tube SZ144000751

The Function of This Polyamide Tube

The SZ144000751 polyamide tube serves as a critical air line for the vehicle’s pneumatic system, primarily in air brake or suspension circuits. Polyamide 12 is the preferred material for air brake systems due to its excellent balance of flexibility, pressure resistance, and long-term durability in harsh conditions.

The OEM-specified length of this SZ144000751 tubing provides the exact reach required for specific routing from the air dryer to the primary reservoir or from the foot brake valve to the rear axle chambers. The color-coding aids in maintenance and troubleshooting.

Unlike traditional rubber hoses, this SZ144000751 polyamide tube offers superior resistance to ozone, UV radiation, and a wide range of chemicals. It maintains structural integrity across a broad temperature spectrum, ensuring reliable braking performance in extreme climates.

The material’s low moisture absorption rate prevents freeze-ups in winter conditions, a common failure point in inferior tubing. This feature is particularly valuable for vehicles operating in cold climates where moisture in the air system can freeze and block the SZ144000751 line.

The tube’s smooth internal bore minimizes pressure drop, ensuring that the air brakes receive full system pressure instantly when the pedal is applied. This responsiveness is critical for the safe operation of a heavy commercial vehicle.

Durable Polyamide Material

This SZ144000751 polyamide tubing resists moisture, chemicals, and temperature extremes. Its low moisture absorption rate prevents freeze-ups in winter conditions, a common failure point in inferior tubing.

The precision-cut ends of the SZ144000751 tube ensure a perfect seal with standard push-to-connect or compression fittings, eliminating the risk of leaks at the connection points.

Polyamide 12 also offers excellent resistance to road salts, diesel, and other common chemicals found in the under-chassis environment. This ensures the SZ144000751 tubing remains flexible and crack-free even after years of exposure to corrosive substances.

Installation and Replacement

Replacement of the SZ144000751 polyamide tube is straightforward: cut the old line, remove any fittings, and install the new tube. Ensure the ends are cut squarely to prevent leaks.

Always use the correct cutting and deburring tools for polyamide tubing. After installation of the SZ144000751 tube, the system must be pressure-tested to ensure there are no leaks before the vehicle is returned to service.

When routing the new SZ144000751 line, ensure it is securely clipped away from moving parts, sharp edges, and heat sources. Proper routing is essential to prevent chafing and premature failure.

Quality Control and Certifications

Each batch of SZ144000751 polyamide tube undergoes rigorous testing to meet international standards such as ISO 14743 for air brake tubing.

We provide full traceability and material certification, ensuring that every meter of SZ144000751 tubing meets the exact specifications required by Shacman for safety and reliability.

The SZ144000751 tubing is tested for burst pressure, tensile strength, and flexibility at both low and high temperatures to guarantee performance in all operating conditions.

When This Tube Needs Replacement

Visible cracking, brittleness, or chafing of the SZ144000751 polyamide tube surface are clear signs of degradation. Even minor chafing can lead to a blowout under pressure.

Persistent air leaks that are not coming from a fitting often indicate a pinhole or split in the SZ144000751 tubing itself. Corrosion or chemical attack on the tubing also warrants immediate replacement.

If the vehicle is being repurposed or the air system is being reconfigured, a new SZ144000751 line of the correct length is essential to maintain system efficiency and safety.

Regular inspection of air lines should be part of every preventative maintenance schedule. Look for signs of wear on the SZ144000751 piping, especially where the tubing passes through bulkheads or near moving components.
