Hydro-Logic Blue Tubing 3/8" for RO and Filtration Runs
This Hydro-Logic line is a 50 ft roll of blue polyethylene tubing built for reverse osmosis and water filtration setups. The 3/8" OD pushes into standard quick-connect fittings, so runs go together without clamps or glue. It resists kinks, which keeps pressure steady from the filter to the reservoir. Cut it square and it seats clean in a push-connect collet for a leak-free seal. Growers use it to extend a feed line, add a branch, or swap out a worn section.
3/8 RO Tubing That Fits HydroLogic Systems
It's sized to fit most HydroLogic filters, including Evolution-RO, ARCS, ecospring, and Merlin-Garden Pro. Run it as a replacement line. Or plumb a custom RO feed with it. The blue jacket makes it easy to tell your clean-water line from nutrient plumbing at a glance. One thing to check: 3/8" here is the outside diameter, so match your fittings to 3/8" OD, not 3/8" ID. A 50 ft roll covers most single-system runs with length to spare.
