Is the Thermoplastic double hose with polyester braid OLB7 suitable for hydraulic oil at +90Â°C and what is its maximum working pressure at that temperature?

Yes. Thermoplastic double hose with polyester braid OLB7 is suitable for hydraulic oil at +90Â°C. Its operating temperature range goes up to +100Â°C, so +90Â°C is within specification. Maximum working pressure at that temperature equals the hoseâs rated working pressure for its diameter, which ranges from 140 bar to 210 bar. Therefore, at +90Â°C the maximum working pressure will be between 140 bar and 210 bar depending on the specific hose diameter selected.

Can Thermoplastic double hose with polyester braid OLB7 be used for fuels and water-based fluids at +80Â°C and what is its max working pressure then?

Yes - Thermoplastic double hose with polyester braid OLB7 can be used for fuels and water-based fluids at +80Â°C for fuels, but not for water-based fluids: the hoseâs overall operating temperature range is â40Â°C to +100Â°C, however the specification limits water and air applications to up to +70Â°C. Maximum working pressure depends on diameter and ranges from 140 bar to 210 bar; at +80Â°C for fuels you should expect the same rated working pressure for the given diameter (140â210 bar), but for water-based fluids use is limited to â¤+70Â°C so +80Â°C is outside the recommended range.

Can Thermoplastic double hose with polyester braid OLB7 handle compressed air at -30Â°C and what is its working pressure?

Yes. Thermoplastic double hose with polyester braid OLB7 can handle compressed air at â30Â°C. Its operating temperature range is â40Â°C to +100Â°C (for water and air up to +70Â°C), so â30Â°C is within the allowable low-temperature limit. The working pressure depends on hose diameter and ranges from 140 bar to 210 bar.
