John Guest 1/2" Blue Tubing is commonly used in conjunction with John Guest Push Fit fittings for water dispensers and coolers, hot brewing appliances, beverage vending machines, ice makers and beer/drinks dispense.
Technical Specifications
Outer Diameter (OD): 1/2"
Inner Diameter (ID): 0.375"
Tube Tolerance: +0.001/-0.004"
Minimum Bend Radius: 1.00"
Potable Water Applications
John Guest LLDPE tubing is suitable for potable cold water applications with a maximum chlorine content of 4 parts per million (4ppm). Heating water above 20°C and/or pressures above the maximum will significantly reduce service life. Direct exposure to sunlight will also significantly reduce its useful service.
UV Resistance
Only black LLDPE tube should be installed in areas exposed to any light if biofilm growth is considered an issue. In this case, any other coloured tube must be protected from light exposure. Black LLDPE tube is also UV stabilised and can be installed where exposed to direct or indirect sunlight (UV).
Tube Inserts
If the LLDPE tube is used in a warm water system a tube insert is necessary.
