The John Guest LLDPE range of plastic tubing is produced in Linear Low Density Polyethylene for cold and intermittent hot water applications.

John Guest tubing provides the benefits of a wide range of temperature and pressure suitability, broad chemical compatibility and is made from non contaminating materials. Common applications are in water purification, water conditioners, ice makers and misting systems. LLDPE is more robust than traditional low or medium density polyethylene and is recommended for use with cold and intermittent hot water. John Guest tubing is made from FDA compliant materials and is NSF International certified. Manufacturered in the United Kingdom.

John Guest Polyethylene tubing is designed for use with John Guest Super Speedfit push-in fittings, John Guest Shut-Off Valves and virtually all standard tubing connectors.

Maximum Working Temperature 150°F at pressures shown in the chart above. For temperatures above 150°F customers should refer to John Guest Technical Help Desk.

Please note maximum pressure rating for a 'system' depends on the lowest rated component, e.g. most John Guest fittings have a different rating than the tube ratings shown above.

Burst pressures are approximately 3 times the maximum working pressure.

LLDPE is not recommended for mineral oils, gases and fuels or high pressure compressed air / pneumatic systems.
