Description
Product Overview
The Fitting Store 4‑loop PEX manifold is engineered for radiant heating applications, offering a robust metal construction that resists corrosion and mechanical stress. Each of the four branches features demagnetized tubing to prevent impurity buildup, and the manifold includes red and blue handles with 1/2″ ball valves for precise flow adjustment. Designed for easy integration, the unit fits standard 1″ trunk lines and connects directly to PEX piping, simplifying installation and maintenance.
Usage
This manifold is perfect for homeowners installing under‑floor heating, contractors outfitting multi‑zone commercial spaces, and retrofit projects in older buildings. It can be mounted in utility closets, under sinks, or within dedicated heating cabinets, providing a clean, centralized control point for up to four heating loops.

FAQ
Can this manifold be used with existing PEX piping?
Yes, the manifold is designed to connect directly to standard 1″ PEX trunk lines and includes compatible fittings for 1/2″ branch connections.
What is the purpose of demagnetized tubing?
Demagnetized tubing reduces the risk of metal particles and other contaminants entering the water, helping maintain system efficiency and longevity.
Is the manifold suitable for outdoor installations?
While the metal body is corrosion‑resistant, we recommend installing the manifold in a protected indoor environment to avoid exposure to extreme weather.
How do I balance the flow between zones?
Adjust each ball valve using the red or blue handle until the desired temperature and flow rate are achieved in each loop, ensuring balanced heating throughout the space.
What warranty does Fitting Store offer?
The manifold comes with a one‑year limited warranty covering manufacturing defects and material failures.
