Red 3/8″ Polyethylene RO Tubing

Polyethylene Tubing for Reactors & Reverse Osmosis Systems

Red RO Tubing is typically used to designate that the water flowing through it is unfiltered. For example, 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.

Made in the USA, Mur-lok Linear Low-Density Polyethylene (LLDPE) tubing is designed for use with all Mur-lok and John Guest push connect fittings. Mur-lok polyethylene tubing offers excellent pressure and temperature ratings and has outstanding resistance to environmental stress cracking, surpassing 1000 hours of ASTM D1693 (10% IGEPAL testing). The tubing is BPA-Free, FDA approved materials and is NSF Standard 58 Certified. The Mur-lok LLDPE Tubing is NSF 58 Component Certified. The products were put through rigorous structural and material testing to help ensure they meet the standards for drinking water. This certification also ensures that our Mur-lok tubing can be easily incorporated into any NSF certified drinking water system with minimal paperwork and minimal, if any, re-testing.
