Meet a smart, multi-zone distribution solution built for efficiency and reliability: the Apollo Expansion PEX / Pex A 3/4 in. Expansion PEX to 1/2 in. D PEX Plastic 6-Port Manifold. This compact, durable unit is purpose-built to bridge larger expansion PEX runs with smaller-diameter PEX circuits, delivering clean, balanced flows across up to six outlets. Ideal for radiant floor systems, domestic hot water distribution, and multi-zone plumbing, it keeps installations tidy and leak-free from the first connection to the last.
Why this Apollo 6-Port Manifold stands out
-
Expansion-to-PEX transition: End 1 uses 3/4 in Expansion PEX, seamlessly stepping down to End 2’s 1/2 in PEX ports. This reduces the need for additional adapters and minimizes potential leak points in multi-zone layouts.
-
Six-port versatility: Six individual outlets give you the flexibility to run multiple zones—think separate bathroom and hydronic floors, or distinct hot water feeds—while keeping a single, tidy manifold assembly.
-
Lead-free, plastic construction: Safe for potable-water applications, with a durable plastic body designed to resist corrosion and wear over time.
-
ANSI-certified: Built to meet industry standards for quality and performance, giving you confidence on the job and for code compliance.
-
High-temperature, high-pressure tolerance: Handles up to 100 psi and up to 200°F, making it suitable for hot-water distribution and radiant heating needs.
-
Bulk packaging, single unit: Ready to integrate into your project without excess packaging waste, ideal for contractor jobsites or bulk inventories.
Where it shines: use cases and applications
-
Radiant floor heating zones: Route different loop circuits from a single manifold, balancing flow to each room or zone for consistent warmth and efficiency.
-
Multi-zone domestic hot water distribution: Supply hot water to several fixtures from one central manifold, reducing joint connections and potential leak points.
-
Compact retrofit projects: Replace bulky fittings with a streamlined manifold when upgrading legacy piping, especially in tight spaces.
-
New construction plumbing runs: Simplify layout planning by consolidating upstream expansion PEX and downstream PEX branches into one organized manifold.

Practical tips for install and optimization
- Plan zone layouts before assembly to maximize the 6-port configuration and minimize crossover piping.
- Use the expansion PEX tool correctly on End 1 connections to ensure a durable, leak-free seal; verify each port after installation with a quick pressure test.
- Label each outlet during install for easier future maintenance or zone adjustments.
- Pair with compatible Apollo Expansion PEX and PEX A components to preserve system integrity and warranty coverage.
Designed for professionals and DIYers alike, the Apollo Expansion PEX / Pex A 3/4 in. to 1/2 in. D 6-Port Manifold delivers reliable multi-zone distribution, tool-friendly installation, and peace of mind for potable-water and radiant heating projects. Whether you’re upgrading an existing system or outfitting a new build, this manifold helps you streamline connections, reduce fittings, and achieve balanced flows across all zones.
