Radiant Heat Manifold, 4-Branch 1/2 In PEX, Stainless

4-branch radiant heat manifold delivers balanced loop control for more even, comfortable hydronic radiant floor heating. Built from SUS304 stainless steel with high-temperature and corrosion resistance, it supports fast heat distribution while helping prevent “water grabbing” between circuits. Dual temperature gauges (°F/°C) and visual flow meters make system tuning quicker, while included 1/2" adapters streamline tie-in to PEX tubing for clean, professional installs.

• Delivers balanced flow to each loop with visual flow meters and shut-off control for smoother, more consistent heat


• Includes 1/2" adapters plus mounting brackets to simplify connecting PEX tubing and securing the manifold


• Controls temperature at a glance with 2 gauges showing both Fahrenheit and Celsius


• Handles high-demand systems with up to 0–5 L/min flow range for efficient hydronic circulation


• Resists corrosion and heat with SUS304 stainless steel construction for long-term reliability

Designed for hydronic radiant floor heating in residential or commercial spaces, this stainless steel PEX manifold kit helps you fine-tune each heating loop for steadier comfort and efficient operation. The 1" inlet/return ball valves provide straightforward isolation during setup or servicing, while the intuitive layout supports faster commissioning and easier adjustments season after season. If you’re upgrading an existing radiant system or building new, this manifold keeps installation clean and control precise—grab yours today and get your system dialed in.
