Do not kink, twist, or bend the hose so tightly that oil flowing in the hose is blocked or reduced. Periodically inspect the hose for wearing, because any of these conditions can damage the hose. 8.WREN JH series 100Mpa high pressure hose's operating pressure is 100Mpa,. Overpass this pressure is forbidden.
