John Guest Quick Connect Tee Fitting - 1/4in QC

John Guest 1/4in QC Tee Fitting — Three-Way Junction for Hydroponic Water Systems

This John Guest-format 1/4in Tee Fitting splits or joins water lines at a T-junction with the same tool-free push-fit ease as the rest of the QC line. Push 1/4in tubing into each port and it locks in place, which makes the tee useful for customizing RO system layouts, adding reservoir feeds, or branching supply lines in hydroponic setups.

Frequently Asked Questions

What is a tee fitting used for?

A tee fitting creates a T-junction in a water line, letting you split one line into two, or merge two lines into one, at a single connection point. It is a common way to add a branch feed without re-plumbing an entire line.

Do I need tools to install this tee?

No — push 1/4in tubing into each port until it clicks. All three ports use the same push-fit design for tool-free installation.

Can I use this in my Hydro-Logic RO system?

Yes — this 1/4in QC tee is compatible with Hydro-Logic systems and any other water purification or hydroponic setup using 1/4in QC tubing. No adapters are needed as long as your lines already use 1/4in QC tubing.

How do I disconnect the tubing?

Press the collet ring at any port inward while pulling the tubing to release it without damaging the fitting or tubing. Both the fitting and the tubing can be reconnected afterward without loss of seal integrity.
