A 90° elbow stem connector that joins standard 1/4″ OD tubing to a 1/4″ stem port — the push-in stem plugs directly into inline filters, RO membrane housings, and other stem-port components. Tool-free push-to-connect, sold as a 2-pack.

What it does

This 90° elbow stem connector links standard 1/4″ OD tubing to a component that has a 1/4″ stem port — such as an inline filter, RO membrane housing, or other push-fit accessory. One side is a push-to-connect port for your tubing; the other is a 1/4″ stem that plugs straight into the mating fitting or port. No thread, no tape.

The 90° elbow shape turns the run at a right angle right at the connection, keeping installs compact in tight spaces (behind a countertop unit, inside an RO enclosure) and reducing stress and sharp bends on the tubing. Because it uses a stem rather than a thread, it’s the fitting you reach for when your component accepts a plug-in stem instead of a threaded port.

Good to know before you buy

• Plug the 1/4″ stem into the mating stem port or fitting on your component until it seats fully.
• Cut the tubing square (90°) and push it fully into the quick-connect side until it seats. Give the tube a gentle tug to confirm it’s held.
• To remove tubing: press and hold the collet ring flat against the fitting, then pull the tube straight out.
• Confirm your component accepts a 1/4″ stem (not a threaded port) and your tubing is 1/4″ OD.
• Check all connections for leaks before putting the system into service. Cold / potable water only.
