Is FM040 steel braided thermoplastic hose compatible with hydraulic oils, gases, fuels, air, and water-based fluids across its full temperature range?

Yes. FM040 steel braided thermoplastic hose Format is compatible with hydraulic oils, gases, fuels, air and water-based fluids within its specified operating limits. It is specifically designed for hydraulic oil installations and for gases, air, fuels and water-based fluids, with a polyester inner layer, steel braid reinforcement and microâperforated polyurethane outer layer. Its operating temperature range is â40Â°C to +93Â°C; note that for air and water the upper limit is +65Â°C. Ensure working pressures (97â330 bar, depending on diameter) and the specific fluidâs chemical compatibility with polyester and polyurethane are suitable for your application.

Can FM040 steel braided thermoplastic hose handle continuous use at its maximum working pressure across all diameters?

No - FM040 steel braided thermoplastic hose should not be assumed safe for continuous use at its maximum working pressure across all diameters. The specified working pressure range (97â330 bar) depends on diameter; continuous operation at the top end may reduce service life and increase risk of failure due to fatigue, temperature effects, dynamic loads or fluid type. Follow manufacturerâs detailed ratings per specific diameter, apply appropriate safety factors, consider duty cycle, temperature limits (â40Â°C to +93Â°C, with water/air up to +65Â°C), and perform regular inspections. If continuous high-pressure operation is required, consult the manufacturer or engineering guidance to confirm suitability and any derating.

Does FM040 steel braided thermoplastic hose require special fittings for micro-perforated polyurethane outer layer?

FM040 steel braided thermoplastic hose does not inherently require special fittings solely because of its micro-perforated polyurethane outer layer. However, selection and preparation of fittings should consider several practical points to ensure performance and longevity: - Compatibility: Use fittings compatible with the polyester inner layer and steel braid reinforcement. Standard hydraulic fittings designed for steel-braided hoses are typically suitable. - Outer layer condition: The micro-perforated polyurethane outer layer may allow fluid migration to the exterior under certain conditions. Ensure fittings seal and clamp the hose without damaging the outer layer; use ferrules or clamps sized for the hose OD and designed to compress to the braid/inner layers rather than the outer jacket. - Sealing and clamping: Use crimp or swage fittings that penetrate to the reinforcement level for reliable pressure sealing (working pressures 97â330 bar). Mechanical or reusable fittings must ensure sufficient bite into the braid; verify manufacturer recommendations for crimp depth and ferrule design. - Corrosion and exposure: Because the outer polyurethane is micro-perforated, fluids reaching the braid could cause corrosion over time. Consider using corrosion-resistant fittings (stainless steel) in aggressive environments. - Temperature and media: Match fittingsâ materials and seals to the operating temperature range (â40Â°C to +93Â°C; for water/air up to +65Â°C) and the media (hydraulic oil, gases, air, fuels, water-based fluids). - Assembly best practice: Trim jacket cleanly where the fitting needs to engage; avoid leaving loose or damaged jacket material between fitting and hose that could trap contaminants. If jacket integrity is required, consider a protective sleeve or sealing compound specified by the hose manufacturer. In summary, FM040 steel braided thermoplastic hose can use standard steel-braided hose fittings, but choose fittings and assembly methods that engage the braid, protect against fluid migration and corrosion, and respect temperature and media compatibility. When in doubt, follow the hose manufacturerâs fitting recommendations.
