It’s particularly well-suited for bathroom and kitchen remodels, laundry room updates, or any retrofit that leverages PEX-A tubing without soldering.

Installation tips
- Cut and deburr each PEX end square to ensure a clean seal.
- For the End 1 3/4 in expansion port, use the Apollo expansion tool to prepare the tubing, then slide the 3/4 in PEX onto the corresponding port until fully seated.
- For the End 3 1/2 in Expansion PEX A Barb port, expand the 1/2 in PEX-A tubing with the expansion tool and push it onto the barb until it sits flush with the port.
- Inspect all connections for proper seating, then perform a pressure test according to local code to verify leak-free operation.
- Use only compatible Apollo PEX-A tubing with this brass tee to maintain the integrity of the expansion seal.
With its robust brass construction, precise expansion-based fittings, and clear sizing (3/4 in to 1/2 in), this Apollo tee delivers a practical, long-lasting solution for modern PEX-A plumbing. It’s a smart choice for anyone prioritizing reliability, fixture-friendly branching, and a clean, solder-free installation that stands up to daily use.
