The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-

draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with

Certified non-conductive

 — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid 

reinforcement,  and  weather  resistant  thermoplastic  or  synthetic  rubber  cover. 

Hose labeled 

certified  non-

conductive is the only hose authorized for use near electrical conductors.

Wire-braided

 (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-

ment, and weather resistant synthetic rubber cover.

ner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover.
