EN856 4SH High-Pulse Breaker Rubber Hydraulic Hose
In heavy machinery such as hydraulic breakers, large excavators and mining drills, the main hydraulic lines suffer extreme working conditions including high-frequency impact, severe vibration and pressure fluctuation. LETONE EN856 4SH high-pulse breaker rubber hydraulic hose is built under EN856 4SH standard, with 4-spiral steel wire reinforcement, sizes 5/8", 3/4", 1", 1-1/4", 1-1/2", 2", and working pressure 45MPa to 25MPa, ideal for heavy-impact and high-flow hydraulic systems.
