Is the Thermoplastic hose with aramid braid OL8 compatible with hydraulic oils, gases, air, fuels and water-based fluids across its full temperature range (-40Â°C to +100Â°C)?

Yes . the Thermoplastic hose with aramid braid OL8 Format is compatible with hydraulic oils, gases, air, fuels and water-based fluids across its stated operating range, with one important limitation: the hoseâs general operating temperature is â40Â°C to +100Â°C, but for water and air the maximum recommended temperature is +70Â°C. In other words, for hydraulic oils, gases and fuels you may use the full â40Â°C to +100Â°C range; for water-based fluids and air limit use to â40Â°C to +70Â°C. The hose meets SAE 100R8 / ISO 3949-R8 construction (polyester inner tube, double aramid braid, micro-perforated polyurethane cover) and working pressures from 145 to 420 bar depending on diameter.

Can Thermoplastic hose with aramid braid OL8 maintain its working pressure (145â420 bar) across all diameters and temperatures?

Thermoplastic hose with aramid braid OL8 cannot maintain a single fixed working pressure across all diameters and temperatures. Its working pressure ranges from 145 to 420 bar depending on hose diameter - smaller diameters reach higher pressures, larger diameters lower. Temperature also affects performance: the specified operating range is â40Â°C to +100Â°C (for water and air up to +70Â°C); at elevated temperatures the hoseâs pressure capacity may be reduced and safety margins change. Always use the manufacturerâs pressure ratings for the specific OL8 hose diameter and consult temperature correction charts or technical datasheets for pressure derating at extreme temperatures.

Does Thermoplastic hose with aramid braid OL8 resist micro-perforation damage from oils, fuels, or solvents over time?

Thermoplastic hose with aramid braid OL8 offers good resistance to micro-perforation from oils, fuels, and many solvents thanks to its construction, but it is not invulnerable and long-term performance depends on service conditions. Why it resists: - Inner polyester tube: compatible with hydraulic oils, fuels and many industrial fluids, providing chemical resistance and preventing internal degradation that can lead to perforation. - Double aramid braid reinforcement: aramid fibers give excellent strength and cut/abrasion resistance compared with textile braids, reducing mechanical wear that can initiate micro-perforations. - Polyurethane outer layer (micro-perforated): polyurethane is generally resistant to oils, fuels and many solvents and offers good abrasion resistance, protecting the reinforcement from external chemical attack and mechanical damage. Limitations and caveats: - Polyurethane resistance is good but not universal; aggressive solvents (certain aromatics, ketones, strong polar solvents) and prolonged exposure can soften or swell the outer layer, eventually allowing fluid ingress and micro-perforation over time. - The micro-perforated outer layer indicates intentional small perforations for breathability/drainage; these features can permit oil/fuel contact with reinforcement under certain conditions, increasing risk compared with a fully sealed outer cover. - Elevated temperatures near the upper limit (+100Â°C) or repeated thermal cycling accelerate chemical attack and mechanical fatigue, shortening resistance lifetime. - Pressure cycling (up to 145â420 bar depending on size) and mechanical abrasion, bending, or installation damage also raise the likelihood of micro-perforation over time. Practical recommendation: For typical hydraulic oil, fuel and air applications within specified temperature and chemical compatibility, Thermoplastic hose with aramid braid OL8 will resist micro-perforation reasonably well. For long-term exposure to aggressive solvents, continuous high temperatures, or critical/fluid-sensitive systems, verify chemical compatibility with manufacturer data and consider a sealed outer cover or alternative material specifically rated for the solvent and temperature involved.
