Single-pack, bagged packaging ensures you get a focused, ready-to-use connector without bulk.
Ideal use cases
This expansion-to-barb tee is perfect when you need a clean, compact branching point in a 3/4 in PEX network. Use it to:
- Create a branch from a main 3/4 in PEX-A loop to a secondary line without sacrificing system integrity.
- Integrate a radiant floor heating circuit with a reliable brass tee that handles frequent temperature changes.
- Facilitate potable water distribution in tight spaces where traditional push-to-connect or crimp-only fittings are less practical.
Installation at a glance
- Prepare all tubing: cut square and deburr the ends for a smooth fit.
- Expand the 3/4 in PEX-A end with a compatible Apollo expansion tool according to manufacturer guidelines.
- Slide the expanded PEX-A onto the expansion end of the tee, ensuring full seating.
- Attach your two 3/4 in PEX runs to the barb ends using appropriate clamps or crimp rings, depending on your system design.
- Perform a pressure test and check for leaks before finalizing the installation.
Practical tips for best results
For reliable performance, pair this brass tee with high-quality PEX-A tubing and properly rated clamps. Avoid excessive bending near the fittings and keep expansion ends free of debris to maintain a clean, leak-free seal over time.
What makes it a smart choice
The Apollo PEX-A Brass Tee embraces the strengths of expansion technology on one end and the versatility of barb connections on the other two. This combination reduces the number of separate fittings in a run, minimizes potential leak points, and delivers a robust, code-compliant solution for 3/4 in PEX networks. If you’re upgrading a manifold, branching a supply line, or integrating radiant heating, this tee provides a precise, dependable connection that stands up to everyday use.
