Is HRT AB Automotive Air Hose suitable for pneumatic brake systems operating between -40°C and +100°C with a working pressure of 10 bar?

Yes. HRT AB Automotive Air Hose Format is suitable for pneumatic brake systems operating between -40°C and +100°C with a working pressure of 10 bar. The hose is specifically engineered for automotive pneumatic brake installations, made from TPE (polyester-based) without plasticizers to maintain long-term flexibility. It is rated for a 10 bar working pressure and has an operating temperature range of -40°C to +100°C (note: up to +65°C when used with water-based media). It also meets ISO 7628:2010 (category 1) and features UV-resistant outer surface and calibrated OD for reliable assembly and durability in demanding conditions.

Can HRT AB Automotive Air Hose maintain flexibility and resist hardening over time without plasticizers when used in automotive pneumatic brake systems?

Yes. HRT AB Automotive Air Hose is formulated from an advanced polyester-based thermoplastic elastomer (TPE) that delivers long-term flexibility and resists hardening without the need for plasticizers. The material’s composition and UV-resistant surface ensure the hose remains supple under automotive pneumatic brake system conditions across a wide temperature range (−40°C to +100°C, up to +65°C for water-based media). Built to ISO 7628:2010 (category 1) and rated for 10 bar working pressure, it maintains dimensional stability and performance under mechanical and environmental stress, offering a durable, maintenance-free solution that minimizes stiffness or embrittlement over time.
