Implementation Standards：It exceeds the ISO18752-AC/CC standard.
Bending radius：It reduces pressure by 41% compared to the ISO 18752 standard; it reduces pressure by 47% compared to the SAE standard; and it exceeds the SAE standard by 60%.

Product Advantages

Super Artery hose features low bending, high pressure, and long lifespan (using Letone's exclusive one-piece hose fittings, weather-resistant for over 5 years, with a 2-year warranty). It has been tested under industry-leading conditions of one million impulse cycles (weather-resistant for over three years), and its bending radius is 30% lower than the SAE/DIN standard.

Softness

Low-temperature bending performance: under -40°C testing conditions, the bending radius is reduced by 50% compared to the DIN EN853 standard; the bending radius of the 1” 42MPa Super Artery low-bending series hose is approximately 250mm.
Impulse performance

Tested with impulses at 1.33 times the working pressure, performance exceeds 1 million impulse cycles.
abrasion resistance

The wear of the ultra-wear-resistant outer layer was 0g under experimental conditions.
Explosive

4 times the work pressure

Frequently Asked Questions

Use and maintenance of rubber hoses

(I) Select the correct type and size of hose according to the usage conditions to prevent misuse and substitution. It is strictly forbidden to use low-pressure hoses instead of high-pressure hoses, or to use ordinary (air or water) hoses instead of special hoses for conveying corrosive media such as acids (alkalis) or oils.
(II) For hoses conveying acids (alkalis), oils, etc., the medium inside the hose should be drained after each use, and the hose should be cleaned promptly to prevent residue from corroding the hose body.
(III) Hose used seasonally must be cleaned and properly stored after use.
