Super Hercules Long Life Excavator Hose Introduction

The bending radius of the long-life excavator hose of Letone Super Hercules is 34% lower than the ISO18752 Class C standard, and the number of hose pulses exceeds 1 million times. With the use of Letone Technology's self-developed hose joints and hydrogenated nitrile seals, the service life can be prolonged. More than 5 years (two years of warranty), and strive to provide five "province" services of "time saving, labor saving, trouble saving, money saving and worry saving".
