Watts Stainless Steel Manifolds

The ONLY radiant floor manifold we recommend

Brass isn’t always best when it comes to manifolds; try Watts radiant floor heating and switch to stainless steel manifolds.

Quality Materials and Construction

Made from heavy-walled, DIN-standard stainless steel tubing, we ship the manifolds directly from Germany’s finest steel mills. The stainless tubing is carefully milled and machined by CNC machines and robotically welded to meet professional standards.

For a durable and long-lasting product, seats are machined and threaded into the manifold, not stamped and pressed in like lesser-quality brands.

Features

Manifolds come pre-attached to mounting brackets with vibration absorbing clamps, priced in pairs. Nominal 1" diameter trunks can be joined together to serve more circuits. Visual flow meters (gpm) are located on the supply manifold and combo balancing/shut off valves on the return manifold.

Professional Appearance and Easy to Use

Manifolds are visible to builders and homeowners, and stainless steel offers a professional appearance. To match the appearance of PEX tubing, fittings and accessories are made of solid brass. Installation of these manifolds is easy with one-piece construction.

For your convenience, optional accessories are available. Browse the PDF guides for a full list of features and for additional information.
