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

John Guest tubing is accepted by almost all of the world’s beer and beverage producers and 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 70°F (20°C) and/or operating at pressures above the maximum specified limits will significantly reduce the service life of the tubing. Direct exposure to sunlight will also significantly reduce its useful life. 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. **SPECIFICATIONS** – Pipe Size: 1/2″ – Suitable for cold and intermittent hot water applications – Odorless, tasteless, and non-toxic – Broad chemical compatibility – FDA- and NSF-certified – Strong, flexible, and robust – Maximum Working Temperature: 150°F – Maximum Working Pressure: 230 psi – Minimum Working Temperature: 33°F **PNEUMATIC APPLICATIONS** – John Guest LLDPE tubing is suitable for pneumatic applications, provided the pressure does not exceed 10 bar at 20°C (150 psi at 70°F). – At elevated temperatures (50°C+), mineral oil will degrade LLDPE tubing. Therefore, LLDPE tubing used in pneumatic circuits should be checked periodically and replaced if necessary. **EXPOSURE TO ULTRAVIOLET LIGHT** – Only black or blue tubing should be installed in areas exposed to light if biofilm growth is a concern. – Black tubing is UV-stabilized and can be installed in areas exposed to direct sunlight (UV). – Other tubing colors must be protected from exposure to light. **TUBE INSERTS** – A tube insert is necessary when the tubing is used in a warm water system. **CHEMICAL COMPATIBILITY** For use with chemicals or other potentially aggressive liquids, please contact John Guest Customer Services at (001) 973-808-5600. **IMPORTANT NOTE** Super Speedfit fittings and related products are not recommended for use with explosive gases, petroleum spirits, other fuels, or central heating systems.
