The Apollo 1/2 in. Expansion PEX Tee is a precise, three-port plastic fitting designed for clean, reliable PEX piping configurations. Built for expansion PEX A on two ports and a PEX-to-PEX connection on the third, this tee anchors branch lines with a secure, leak-resistant seal that’s ideal for residential plumbing and radiant systems.
Key benefits you’ll notice in real-world installs:
-
Three 1/2 in. ports tailored for small-diameter PEX lines, enabling quick branch connections without sacrificing flow.
-
Expansion PEX A compatibility on End 1 and End 3 delivers a robust, tool-assisted fit that minimizes crimps and fittings where precision matters.
-
End 2 PEX compatibility supports standard PEX runs, giving you flexible, mixed-material branching options in a single fitting.
-
Lead-free, plastic construction designed for safe potable-water service with long-term durability in typical indoor environments.
-
ANSI certified and engineered for reliable performance within its rated specs, giving you peace of mind on code-compliant projects.
-
Pressure and temperature tolerance rated up to 200 (psi/°F), suitable for typical household and radiant heating applications.
-
Bagged in sets of 10 for convenient inventory management on larger projects or multi-branch installations.
How it fits into common projects:
- Branching a main 1/2 in. PEX line to serve multiple fixtures without adding extra elbows or adapters.
- Creating a dedicated line for a small appliance, fixture, or zone valve within a home’s plumbing or radiant floor loop.
- Retrofits where expansion PEX A is already part of the system and you need a coordinated tee for a clean run.
Why choose this Apollo expansion tee over other options? Its design emphasizes compatibility and reliability: two expansion PEX A ends provide the strong, secure joints that expansion systems are known for, while the third end accommodates a standard PEX path, reducing the need for additional adapters. The result is a straightforward install process, fewer leak points, and a tidy piping network that’s easier to inspect and maintain.
Practical notes for use:
- Ensure tubing ends are clean and properly prepared for expansion or barb insertion according to PEX-A and PEX guidelines.
- Verify system pressure and temperature are within the 200 psi / 200°F range for uninterrupted performance.
- Inspect joints after initial fill and test for leaks before burying or concealing the piping.
