Frequently Asked Questions

Which HydroLogic systems does this tubing fit?

This 3/8in OD tubing is designed for HydroLogic Evolution-RO and Merlin-Garden Pro systems. Verify your system's tubing size before ordering, since different HydroLogic product lines use different OD sizes.

Can I use this tubing with non-HydroLogic fittings?

Yes — standard push-fit or compression fittings sized for the matching OD are compatible with this tubing. Confirm the fitting's rated OD matches the tubing size before assembly.

Why are there two colors available for each size?

Black and blue color options make it easy to differentiate feed water, product water, and drain lines during installation and troubleshooting. This is especially useful on systems with multiple parallel lines running to the same area.

How do I cut the tubing cleanly?

Use a sharp tubing cutter for a clean, square cut. A clean cut ensures a proper seal when the tubing is inserted into push-fit fittings.
