DIFFUSION ABRASION SLEEVE (DAS)
Diffusion Abrasion Sleeve (DAS)
Experience the pinnacle of textile sleeve technology with our Diffusion Abrasion Sleeve (DAS). Unveiling a new standard in compactness, strength, and durability, this specialized sleeve is meticulously engineered to elevate the protection of your equipment.
The DAS is crafted from continuous nylon fiber treated through a unique de-aering process. This process removes air from the textile fibers, causing a controlled 5% shrinkage. This meticulous technique ensures unparalleled compactness and strength, setting the foundation for reliable and robust protection.
With rigorous testing, the DAS has successfully passed the following:
Abrasion Test (ISO 6945), Fire Resistance (USMSHA), Electrical Conductivity (ISO 8031), and
Oil Retention (SAE J 343, 4.4).
Key Features
Streamlined Design
The DAS boasts a remarkably dense construction without compromising on bulkiness, offering a perfect balance of protection and efficiency.
Unparalleled Abrasion Resistance
Equipped with exceptional abrasion resistance, the DAS safeguards your equipment from wear and tear in the harshest of environments.
Expansion Resilience
With a high degree of expansion resistance, the DAS maintains its protective integrity even under pressure and strain.
Leakage Prevention
The advanced design of the DAS effectively reduces concentrated stream pinhole leaks, enhancing operational safety and minimizing disruptions.
Leak Containment
The DAS excels in containing potential leaks, ensuring that your equipment stays operational and reducing potential damage.
Smooth and User-Friendly
The sleek surface of the DAS allows for easy sliding onto hoses, even over extended lengths, streamlining installation and maintenance procedures.
