The Parker Markwel Spiraflex SAE 100 R15 hydraulic hose is a high-performance, heavy-duty hose designed for extremely high-pressure hydraulic applications. With an inner diameter of 1 inch and a working pressure of up to 420 bar (6000 PSI), it is engineered using multiple layers of high-tensile steel wire reinforcement to ensure superior strength, durability, and flexibility. The inner tube is made of oil-resistant synthetic rubber, while the outer cover is designed to withstand abrasion, weather, and harsh environmental conditions. This hose is suitable for petroleum-based and water-based hydraulic fluids and performs efficiently in demanding industrial, construction, and earthmoving equipment. It also offers excellent impulse resistance with up to 500, 000 cycles and operates within a temperature range of -40°C to +121°C.
