Meet the Apollo Expansion PEX / Pex A 3/4 in. Expansion PEX to 1/2 in D PEX Plastic 2 Port Manifold — a precise, reliable junction engineered to streamline small-diameter PEX distribution in residential plumbing projects. Designed to convert a 3/4 in expansion PEX supply into two 1/2 in branches, this compact manifold is ideal for clear, organized water distribution where space is at a premium.
Why this manifold stands out
-
Two-port distribution that efficiently splits a single 3/4 in expansion PEX feed into two 1/2 in PEX lines, reducing the need for multiple fittings and potential leak points.
-
Expansion PEX A technology at End 1 offers a robust, expansion-based connection for a secure, long-lasting seal with compatible PEX-A tubing.
-
End 2 uses standard PEX compatibility to accommodate common 1/2 in PEX runs, giving you flexible options for routing.
-
Lead-free, plastic construction provides corrosion resistance and durable performance in typical potable water applications.
-
Performance envelope rated for up to 200°F and up to 100 psi, making it suitable for a range of residential hot and cold water scenarios.
-
Single-unit package delivers a ready-to-use manifold without additional components, simplifying installation and reducing parts inventory.

- Organize a compact distribution point in tight utility rooms or closets where space saving is essential.
- Combine expansion-based PEX-A connections with standard PEX runs to create neat, efficient plumbing layouts without excessive fittings.
Installation notes
- Plan your route so End 1 (3/4 in Expansion PEX) provides the primary feed, while End 2 (1/2 in PEX) branches to your destinations.
- Use compatible expansion tools and PEX-A tubing for End 1 to ensure a secure, leak-free seal.
- Inspect all connection points after installation and perform a pressure test to verify performance before commissioning the system.
- Avoid exposing the plastic manifold to extreme mechanical stress or unapproved solvents to preserve longevity.
Whether you’re upgrading a small bathroom project, building out a compact hot-water supply, or simplifying a radiant heating feed, this Apollo 3/4 in expansion PEX to 1/2 in D PEX 2 Port Manifold gives you a clean, dependable distribution solution with minimal fuss and compatible integration into your existing PEX layout.
