Is the Thermoplastic double hose with aramid braid OLB8 compatible with hydraulic oils, gases, air, fuels and water-based fluids across its full temperature range (-40Â°C to +100Â°C)?

Yes . Thermoplastic double hose with aramid braid OLB8 is compatible with hydraulic oils, gases, air, fuels and water-based fluids over its specified operating range, with one important limitation: while the hose overall temperature rating is -40Â°C to +100Â°C, compatibility with water and air is limited to -40Â°C to +70Â°C. The hose is specifically designed for those media (standards SAE 100R8, ISO 3949-R8), features a polyester inner tube, double aramid braid reinforcement and a micro-perforated polyurethane outer layer, and has working pressures from 245 to 350 bar depending on diameter.

Can Thermoplastic double hose with aramid braid OLB8 be used with water-based fluids at pressures up to 350 bar?

Yes. Thermoplastic double hose with aramid braid OLB8 Format is specified for hydraulic oil installations, gases, air, fuels and water-based fluids. Its construction-polyester inner layer, double aramid braid reinforcement and micro-perforated polyurethane outer layer-gives working pressures from 245 to 350 bar depending on diameter. Operating temperature range covers -40Â°C to +100Â°C (for water and air up to +70Â°C). Therefore, when selecting the appropriate diameter that provides a 350 bar working pressure and operating within the temperature limits (â¤ +70Â°C for water), this hose can be used with water-based fluids at pressures up to 350 bar.

Can Thermoplastic double hose with aramid braid OLB8 withstand continuous exposure to oils and fuels at 100Â°C?

Thermoplastic double hose with aramid braid OLB8 Format: According to the provided specification, the hose has an overall operating temperature range of -40Â°C to +100Â°C, but with a specific note that for water and air the maximum is +70Â°C. Oils and fuels are explicitly listed among the media the hose is designed for (hydraulic oil installations, fuels). Therefore, continuous exposure to oils and fuels at 100Â°C is within the stated maximum operating temperature for the hose in general. However, because the datasheet limits water and air to +70Â°C, and continuous exposure to aggressive fluids at elevated temperatures can accelerate polymer ageing (inner polyester layer and microâperforated polyurethane outer layer), longâterm service at 100Â°C may reduce hose life compared with lower temperatures. Recommendation: Thermoplastic double hose with aramid braid OLB8 Format can operate with oils and fuels at 100Â°C per the stated maximum temperature, but for continuous highâtemperature exposure verify fluid compatibility and expected service life with the manufacturer, and consider reduced safety margins, periodic inspections, or selecting a hose rated specifically for continuous highâtemperature fuel/oil service if long-term durability is critical.
