Is HYDRAFIX FR211 coolant hose suitable for use with oil-based coolants and grease-contaminated environments at temperatures up to +80Â°C?

Yes. HYDRAFIX FR211 coolant hose is specifically described as oil, grease, and hot chip resistant and designed for low-pressure delivery of liquid or gaseous coolant during metal processing, so it is suitable for environments contaminated with oil and grease. Its material is black PVC with steel guiding reinforcement (and an extra nickel-plated steel spiral cover for DN 10), a working pressure of 4 bar, and an operating temperature rating up to +80Â°C, which matches your temperature requirement. Provided it is used within the stated working pressure (â¤4 bar) and maximum operating temperature (+80Â°C), HYDRAFIX FR211 is appropriate for oil-based coolants and grease-contaminated conditions.

Can HYDRAFIX FR211 coolant hose be used for low-pressure delivery of gaseous coolants in metal processing at 4 bar?

Yes. HYDRAFIX FR211 coolant hose is specified for low-pressure delivery of liquid or gaseous coolants during metal processing and lists a working pressure of 4 bar, so it can be used at that pressure. Its black PVC construction, steel guiding cover (and additional spiral cover on DN10) provides reinforcement suited to that application, and the shape-memory feature allows precise coolant direction. Ensure your operating temperature does not exceed +80Â°C and that connections (BSP/metric threads) and gas compatibility with PVC are acceptable for your specific gaseous coolant and safety requirements.

Does HYDRAFIX FR211 coolant hose maintain its shape memory for precise coolant direction under continuous use?

Yes. HYDRAFIX FR211 coolant hose is designed to maintain its shape memory and keep coolant direction precise under continuous use, within its specified limits. The black PVC material combined with the steel guiding cover (and an extra nickel-plated spiral on DN 10) provides structural reinforcement that preserves the hoseâs preformed shape while resisting deformation from flow and handling. Its operating temperature rating (up to +80Â°C) and working pressure (4 bar) define the normal conditions in which the shape-memory performance is reliable. Caveats: Extended exposure above +80Â°C, pressures above 4 bar, or prolonged mechanical abuse (excessive bending, crushing, or impact) can degrade the PVC and reinforcement over time and diminish shape retention. For best long-term precision, use within the specified temperature and pressure ranges and avoid harsh mechanical stresses.
