When comparing prices, you must evaluate the reinforcement material (e.g., aramid fiber, polyester, or steel wire) as this significantly impacts the Pressure Rating (PN), typically ranging from 70 to 300 bar. Ensure the inner liner material (HDPE, PA, or PVDF) is compatible with the transported medium (oil, gas, or water) to prevent premature failure. Additionally, verify the operating temperature range, as high-temperature resistance (up to 90°C or more) will command a premium price compared to standard water-grade RTP.
