★WATER&FOOD USE:The tubing is food grade Polyethylene (PE) materials and is NSF Certified,which were put through rigorous structural and material testing to help ensure they meet the standards for drinking water.It is ideal for plumbing applications requiring low temperature, flexibility, and durability. | ★SPECIFICATION&COMPATIBLE WITH: 1/4" O.D./Outside diameter(≈6.5mm) X 0.142" I.D./Inside diameter(≈4.15mm）X inside/outside wall thickness ≈1.46mm;Working Temperature: 70°F to 150°F;Max Pressure:120PSI;Compatible with all PureSec quick connect fittings or Compression fittings by others' that utilize 1/4" Polyethylene Tubing. | ★Indoor&Outdoor Use: Common applications include water purification systems, reverse osmosis systems,drinking water filters, refrigerator ice makers and misting systems, car wash systems, home/office coffee and beverage dispensing equipment,and pneumatic lines,and many other application requiring connections for transfer of water and liquids. | ★Easy to Use: Red RO Tubing is used on most reverse osmosis systems to designate that the water flowing through it is unfiltered. On most reverse osmosis systems the red tubing will run from the source water connection through pre-filters and up to the source water input on the membrane. After the membrane the color of the tubing will usually change to blue to designate product water, and black to designate waste-water. | ★Quality&Color Option:Our RO Tubing is Dimensional stability, Uniformity and long-term strength,higher burst pressure, Greater tensile strength. It offers prime pressure and temperature ratings and has outstanding resistance to environmental stress cracking.White/Black/Blue/Yellow/Red Colors available (Check our Storefront to buy).
