Polyethylene Tubing for Reverse Osmosis Systems

Compatible with all Bulk Reef Supply RODI Systems and other RO(DI) systems that utilize 1/4" Polyethylene Tubing. The 1/4" measurement is the outside diameter of the tubing and will work with all 1/4" Push-Connect fittings. 

Black Tubing is commonly used for wastewater lines with reverse osmosis systems and is commonly found coming out of the waste-water fitting on the membrane housing.

Make sure to pick up an RO Tubing Cutter for a perfect cut every time!

 

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.
