Parker 1/4" Union Tee

When a single line needs to branch into two, the Parker 1/4" Union Tee is the fitting that gets it done. With three 1/4" push-to-connect ports arranged in a classic T configuration, it splits flow cleanly and reliably. Parker Hannifin molds it from durable POM polymer, giving you a corrosion-resistant junction that stands up to years of continuous water-treatment service at a featherweight 0.01 lbs. It is a foundational piece for any quick-connect plumbing layout.

Branching Made Simple

This union tee is perfect any time you need to feed two devices from one supply line or merge two returns into one. Common uses include splitting RO product water to a faucet and a refrigerator, teeing off to an ice maker, or distributing line pressure across a small filtration manifold. The equal-diameter ports keep flow balanced between the two branches, which is important when both legs serve fixtures that should receive comparable pressure and volume.

• Three-way tube x tube x tube union tee
• Equal 1/4" x 1/4" x 1/4" ports for balanced flow
• POM polymer body resists rust, scale, and most chemicals
• Push-to-connect design needs no wrenches or sealant
• Reusable collets for easy line changes
• Compact footprint fits crowded cabinets

To install, cut each tube square and free of burrs, then push it fully into each of the three ports until seated against the internal stop. The integral O-rings form an immediate seal, and the locking collets hold the tubes firmly even under system pressure. Releasing a tube is just as easy: press the collet ring and pull. Because no tape or thread sealant is involved, you can reconfigure your plumbing as needs change without creating new leak points. As with all Parker quick-connect fittings, precise molding tolerances ensure a snug, leak-free fit and a long, trouble-free life in home and light-commercial water systems.

For new builds and upgrades alike, keeping a few union tees in your kit means you can split a feed line wherever a project calls for it, without a trip to the hardware store. Combined with elbows, connectors, and valves from the same Parker quick-connect family, this tee helps you assemble a clean, modular, and easily serviced water-treatment system.
