The general-purpose hydraulic hose is engineered for maximum durability and reliability, offering a significantly extended service life proven through rigorous testing of 1,000,000 impulse cycles. Built to meet the demanding requirements of EN 856 4SH and ISO 3862-1 4SH standards, it combines strength with safety, featuring a flame-resistant MSHA-approved outer layer. Its construction includes a black, oil-resistant synthetic rubber inner tube, reinforced with four robust layers of high-tensile steel wire, and a durable outer cover made of oil-resistant synthetic rubber to ensure long-lasting performance even in the harshest environments. Designed to handle working pressures ranging from 250 bar up to 420 bar, depending on the hose diameter, it guarantees consistent efficiency across a wide range of applications. With an operating temperature range from -40°C to +100°C, and the ability to withstand peaks up to +120°C, this hose delivers exceptional versatility and reliability, making it the ideal solution for heavy-duty hydraulic systems where safety, endurance, and performance are critical.
