Product Features

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。

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.。

One-piece non-stripping glue joint (31 and 41 series)

  • 1)Eliminates hose crimping problems caused by stripped or too short hoses;
  • 2)Save manpower, easy to operate;
  • 3)One connector is suitable for multiple hoses;
  • 4)Clean and beautiful after crimping。

Split connector (61 series)

  • 1)More flexibility, more choices of joints and sleeves;
  • 2)Joints and sleeves can be purchased separately according to existing inventory。
Customized Outer Layer Of Hose

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:

  • Standard outer layer:Oil-resistant, abrasion-resistant and weather-resistant synthetic rubber;
  • Abrasion Resistance (AR) outer layer:The wear-resistant quality loss is 1/7 of that of the standard tube outer layer, that is, its wear resistance coefficient is 7 times that of the standard outer layer. Wear-resistant AR outer hose is suitable for relatively harsh environment;
  • Super abrasion resistance SAR (Super >Abrasion Resistance>) outer layer:Using UHMWPE outer layer, the quality loss of outer layer material under 2000 cycles is 0. Super wear-resistant SAR outer hose is suitable for extremely harsh environment。
