Is HRT AB automotive air hose compatible with brake fluids and resistant to oil contamination over long-term use?

HRT AB automotive air hose is designed for pneumatic brake system installations and is made from a polyester-based thermoplastic elastomer (TPE). According to the provided description: - Compatibility with brake fluids: The hose is specified for pneumatic (air) brake systems and lists an operating temperature limit of +65Â°C for water-based media. There is no explicit certification or statement that it is compatible with hydraulic brake fluids (glycol-based DOT fluids or silicone-based brake fluids). Because TPE formulations vary in chemical resistance, and hydraulic brake fluids are aggressive to some elastomers, you should not assume long-term compatibility with hydraulic brake fluids without manufacturer confirmation or chemical-compatibility data. - Resistance to oil contamination long-term: The description emphasizes no plasticizers, no stiffening, UV resistance and suitability for air/water-based media, but does not claim resistance to oils or hydrocarbon-based contaminants. Polyester-based TPEs often have limited long-term resistance to oils and petroleum products. Therefore, HRT AB automotive air hose should not be relied on for long-term oil-contaminated environments unless the manufacturer explicitly certifies oil resistance. Recommendation: Use HRT AB automotive air hose for intended pneumatic (air/water-based) brake applications only, and contact the manufacturer for specific chemical-resistance data if you plan exposure to hydraulic brake fluids or oil contamination.

Does HRT AB automotive air hose maintain flexibility and UV resistance in outdoor installations over time?

Yes. HRT AB automotive air hose maintains flexibility and UV resistance in outdoor installations over time. Made from a polyester-based thermoplastic elastomer (TPE) with no plasticizers, it is formulated not to stiffen and is explicitly resistant to UV radiation. Its operating range (â40Â°C to +100Â°C, +65Â°C for water-based media) and ISO 7628:2010 (category 1) compliance further support suitability for long-term outdoor pneumatic brake system use.

Can HRT AB automotive air hose be safely used with compressed air systems in cold climates down to -40Â°C?

Yes. HRT AB automotive air hose can be safely used with compressed air systems in cold climates down to â40Â°C. The hose is made from a thermoplastic elastomer (TPE) based on polyester, contains no plasticizers (so it wonât become brittle), and is specified to operate between â40Â°C and +100Â°C. Itâs also UV-resistant and designed for automotive pneumatic brake system use, with a working pressure of 10 bar and ISO 7628:2010 (category 1) compliance. These properties make it suitable for compressed air service at temperatures as low as â40Â°C, provided the system pressure does not exceed the hoseâs rated 10 bar and installation follows manufacturer guidelines.
