Note style
Low bend:The average minimum bending radius of the entire series of hoses is 34% lower than the ISO18752 Class C standard (Note: The Class C standard refers to the compact category in the ISO18752 standard), which is easy to install and save equipment space;
High pressure:All pressures meet/exceed ISO18752 AC/BC/CC/DC standards;
Life:Powerful pulse performance, the pulse times of the entire series of hoses are more than 1 million times, which greatly extends the service life of the hose。

The convenience of the Super Hercules low bending series is mainly reflected in three aspects:
1、There is obvious pressure classification, easy to find the model;

3、Adopt one-piece non-stripping glue joints (31 and 41 series) and split joints (61 series))Note: The integrated non-stripping glue and split joints are matched with Litong self-developed hydrogenated nitrile seals, which is infinitely close to the sealing goal of zero leakage.。

Based on EN853: 2015, the outer layer of the Super Hercules low bending hose series is reciprocated at a frequency of 1.25HZ under 25N gravity according to the method specified in the GB/T 12721-2007/ ISO6945: 1991 inspection standard. In the abrasion test, the quality loss of the outer layer material under 2000 cycles is compared, and the outer layer of the Super Hercules low-bending hose is divided into the following three types:
