500 Ft - Red Polyethylene 1/4" RO Tubing Spool

Bulk RO Tubing

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.

Our 500 Foot Spool comes as a complete continuous 500-Foot span of tubing which is perfect for fish stores or service shops to keep on hand. The spool comes with a metal inner ring that makes it convenient to mount on a spindle for quick and easy dispensing of the tube. 

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.

Make sure to pick up an RO Tubing Cutter for easy and clean cuts every time!
