Is the OL7 M Thermoplastic Hose with Polyester Braid suitable for hydraulic oil and air systems at temperatures down to -40°C and pressures up to 250 bar?

Yes. The OL7 M Thermoplastic Hose with Polyester Braid is suitable for hydraulic oil and air systems at temperatures down to -40°C and pressures up to 250 bar, provided you select the appropriate diameter variant that supports the required working pressure (hose working pressures range from 210 to 250 bar depending on diameter). Note: the stated maximum operating temperature for air and water is +70°C, and the hose is designed for Z-type fittings; ensure compatibility with your system and safety margins for your application.

Can the OL7 M Thermoplastic Hose with Polyester Braid be used with water-based fluids and fuels at temperatures up to +70°C while maintaining pressure ratings between 210–250 bar?

Yes. The OL7 M Thermoplastic Hose with Polyester Braid is specified for use with water-based fluids and air at temperatures up to +70°C while maintaining working pressures in the 210–250 bar range (depending on diameter). The hose’s construction—polyester inner layer, double polyester braid reinforcement, and polyurethane outer cover—meets SAE 100R18 and ISO 3949-R18 standards and is explicitly rated for an operating temperature range up to +100°C overall, with the caveat that water and air are limited to +70°C. Therefore it is suitable for your stated fluids and temperature/pressure conditions.
