Product Description

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。

Model Selection

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；

2、Only need to select the corresponding model from the three connector series; Note：31 is hose connector 31 series; 41 is hose connector 41 series; 61 is hose connector 61 series。

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。
