Heavy Duty Four Spiral Hydraulic Hose
The RX-400H is a heavy-duty four-spiral hose for applications requiring high working pressure and high-impulse performance — demolition tools, compaction machinery, hydraulic hammers and severe-vibration environments. Heavy-gauge wire in all four spiral layers provides exceptional burst resistance in the most demanding hydraulic circuits.
