SAE 100 R4 is suitable for low-pressure and vacuum hydraulic lines, used for suction and return of petroleum‑based and water‑based fluids. It features a composite reinforcement of textile fibers and helical steel wires, specifically designed for low‑pressure suction and vacuum oil‑return applications, offering collapse resistance and excellent negative‑pressure tolerance.
Structure: The hose consists of an oil‑resistant synthetic rubber inner layer, a reinforcement layer made of single‑ply or multi‑ply fabric or braided fibers with an appropriate helical steel wire winding, and an outer oil‑ and weather‑resistant synthetic rubber cover.
Applications: Suitable for low-pressure and vacuum applications, using petroleum-based hydraulic fluids.
A hose with a temperature range of -40°C to +100°C.
Size range: Standard inner diameters from 3/4" to 4"; oversized sizes available upon special order.
Application: Suitable for low-pressure hydraulic lines, it can safely suction and return petroleum‑based and water‑based fluids, making it a reliable choice for industrial suction operations.
Service Support: We offer bulk ready‑stock supply, support customized solutions, and provide compatible connectors and accessories to meet the efficient procurement needs of diverse industrial applications.
