The 3/8" O.D. Linear Low Density Polyethylene Tubing (LLDPE) 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 systems, water conditioners, ice makers, coffee brewers and vending machines. The 3/8" O.D. Linear Low Density Polyethylene Tubing (LLDPE) is more robust than traditional low or medium density polyethylene and is recommended for use with cold and intermittent hot water. This polypropylene tubing is designed for use with Push-In fittings, Shut-Off Valves and virtually all standard tubing connectors.
