This RO Female Adapter with 1/4″ FNPT x 1/4″ Quick Connect configuration is designed
to connect a 1/4″ male threaded fitting to 1/4″ OD tubing in reverse osmosis (RO)
and water filtration systems. It provides a clean, reliable transition from threaded ports to push-fit tubing.

The quick connect (push-fit) side allows fast, tool-free tubing installation—simply push the tubing
into the fitting until fully seated. The female threaded side installs onto standard 1/4″ MNPT
ports using PTFE (Teflon) tape for a secure, leak-resistant seal.
