    John Guest LLDPE (linear low density polyethylene pipe) is suitable for a wide range of temperature and pressures, has broad chemical compatibility and is made from non-contaminating materials. It is compatible with pneumatics applications with a maximum pressure 10 bar @ 20°C. At elevated temperatures (50°C), mineral oil used in some systems will degrade LLDPE tubing. Therefore, LLDPE tubing used in pneumatic circuits should be periodically checked and replaced if necessary. Chemical Resistance For use of LLDPE with chemicals or potentially aggressive liquids, please refer to our Technical Service Department. When using cleaning agents or other potentially aggressive liquids, please ensure compatibility with pipe and fittings. LLDPE is not recommended for mineral oils, gases and fuels or high pressure compressed air/pneumatic systems. Exposure to Ultraviolet Light If biofilm growth is considered an issue, only black pipe should be installed in areas exposed to any light. Black pipe is also UV stabilised and can be installed where exposed to direct sunlight (UV). Flexible and robust LLDPE (Linear low density polyethylene) pipe Suitable for air and pneumatics, cold, and intermittent hot water applications Broad chemical compatibility Colour coded for easy identification of service type FDA and NSF certified
