Connects a standard 3/4″ garden or laundry hose outlet to 3/8″ OD quick-connect tubing. The 3/8″ version of the garden adapter — for systems using the larger tubing size. Not compatible with MWC Legacy countertop RO systems (those use 1/4″).

What it does

This adapter screws onto any standard 3/4″ garden hose thread (GHT) outlet and converts it to a 3/8″ OD quick-connect tubing connection. Use it when your system runs 3/8″ tubing and the closest water source is a hose bib, laundry outlet, or utility faucet.

Not compatible with MyWaterClub Legacy countertop RO systems (which use 1/4″ tubing). For Legacy systems, use the 1/4″ garden adapter instead.
