John Guest 1/2" Polyethylene Tubing (250 FT)

John Guest Tubing is accepted by almost all the world’s beer and beverage producers and by the manufacturers of drinks dispenser equipment. John Guest products have quality and performance approvals from leading testing and acceptance authorities. John Guest LLDPE tubing is suitable for potable cold water applications with a maximum chlorine content of 4 parts per million (4 ppm). Heating water above 70ºF (20ºC) and or pressures above the maximum will significantly reduce service life. Direct exposure to sunlight will also significantly reduce its useful service. As part of good practice tubing should be inspected regularly. If there is any evidence of damage, hardening or cracking it should be replaced immediately.
