Is the Thermoplastic Twin Hose Reinforced with Polyester Braid OLB7 suitable for both hydraulic oil and compressed air applications within its specified temperature range?

Yes. Thermoplastic Twin Hose Reinforced with Polyester Braid OLB7 is suitable for hydraulic oil and compressed air within its specified temperature range. It is engineered for hydraulic oil systems and for conveying gases and compressed air. The hose’s operating temperature is -40°C to +100°C, with a specific limitation of up to +70°C for water and air, so compressed air use should be limited to temperatures ≤ +70°C. Working pressures vary by diameter (140–210 bar), and the double polyester braid reinforcement plus polyester inner tube and micro-perforated polyurethane cover provide the necessary strength, abrasion resistance, flexibility, and reliability for both applications when used within these pressure and temperature limits.

Can Thermoplastic Twin Hose Reinforced with Polyester Braid OLB7 be used for potable water or food-grade fluids, and what certifications support this use?

Thermoplastic Twin Hose Reinforced with Polyester Braid OLB7 is designed for hydraulic oil, gases, compressed air, fuels and water-based fluids. However, its description limits the maximum safe temperature for water and air to +70°C and specifies materials (polyester inner tube and double polyester braid) and standards met (SAE 100R7 and ISO 3949‑R7) that are focused on hydraulic and industrial applications, not specifically on potable water or food-grade contact. Therefore, Thermoplastic Twin Hose Reinforced with Polyester Braid OLB7 should not be assumed suitable for potable water or food-grade fluids unless the manufacturer confirms compliance with food-contact and potable-water approvals (e.g., NSF/ANSI 61, ACS, WRAS, KTW, FDA 21 CFR 177.2600 or EU Regulation EC 1935/2004) and provides specific test documentation (extractables, odor/taste, microbial resistance). The listed SAE and ISO standards do not by themselves certify food- or drinking-water safety.
