Watts Radiant offers a wide variety of stainless steel, cast brass, and tubular brass and copper manifolds. All are manufactured in-house or sourced from our sister companies in Europe, Watts Dumser and Watts Cazzaniga. Any of these styles can be fitted with a wide variety of Onix, PEX Crimp, PEX Compression, RadiantPEX-AL Press, or RadiantPEX-AL Compression fittings.

Stainless Steel Manifolds

CazzBrass Manifolds are made of heavy-walled, 1-1/4” cast brass. Manifold sections are offered in three different varieties, allowing five different configurations to meet project needs. Sections are easily conected to each other using built-in swivel union adapters. Note: RadiantPEX-AL fittings are not available for CazzBrass Manifolds

Tubular Copper Manifolds Watts Radiant manufactures a wide variety of copper tubular manifolds from 1” to 6” in diameter. Three styles are available: Custom Tubular Manifolds, CustomCut Manifolds, and Swedged Manifolds. Custom Tubular are sold in pairs; CustomCut and Swedged are sold individually. Nearly any custom configuration is possible to meet the most demanding commercial specification.

Manifolds

Stainless Steel manifolds are made of heavy-walled, DIN-standard stainless steel. Matching fittings and acessories are made of solid brass and are heavily plated with nickel to match the appearance of the manifold trunk. Standard features included flow balancing valves and flow meters. Manifolds are sold in pre-mounted pairs in 1” and 1 1/2” sizes.

Manifolds

These manifolds truly represent state-of-the-art quality and design. Stainless Steel manifolds are made of heavy-walled, DIN-standard stainless steel tubing from Germany’s finest steel mills. This tubing is carefully milled and machined by CNC machines, and robotically welded to meet the most exacting professional standards. Matching fittings and accessories are made of solid brass and heavily plated with nickel to match the appearance of the manifold trunk. Standard features include flow balancing valves and flow meters. Manifolds are sold in pre-mounted pairs. Find tubing fittings in the Onix, RadiantPEX, or RadiantPEX-AL sections.

Stainless Steel Manifolds are sold in pairs, one supply and one return, mounted to metal bracket as shown. Accessories such as Trunk Isolation Ball Valves, Vent/Purge Assemblies, and Actuators are purchased separately. For added convenience, several of these accessories can be purchased in kits (see next page). Each circuit can be individually balanced by adjusting the valve located under the blue cap. Maximum flow rates are 12 gpm for 1” manifolds and 20 gpm for 1-1/2” manifolds. Individual circuit flow meters are 0–2 gpm for 1” and 0–4 gpm for 1-1/2” manifolds. Circuits can be completely isolated by installing Circuit Isolation Ball Valves. Manifolds and gauges are rated to 194°F at 87 psi pressure. Fittings are spaced at 2-1/8” on center. Order Onix, Crimp, or Compression fittings separately. NOTE: Find tubing fittings in the Onix, RadiantPEX, or RadiantPEX-AL sections. Only SS-T20 styles are compatible with Stainless Steel manifolds.

for 1” Stainless Steel Manifolds

IsoTherm for 1” Stainless Steel Manifolds

The IsoTherm is a compact, efficient pre-piped and pre-wired pump and mixing valve control designed to connect to Watts Radiant 1” Stainless Steel Manifolds. With a standard temperature range of 113° to 140°F (45° to 60°C), many different installation types can be accommodated. When combined with Watts Radiant electrothermal Actuators and Watts Radiant Actuator Valve Controls, a complete trouble-free system is created, serving from 1 to 12 zones and delivering up to 50,000 Btu/h (maximum of 68,000 Btu/h with a minimum boiler temperature of 160°F). See Hydronic Accessories for ordering information.

The Pressure Differential By-pass Valve Assembly for 1” Stainless Steel manifolds eliminates water velocity noise and water hammer. This Pressure Differential By-pass Valve installs directly on the 1” Stainless Steel manifolds. This valve adjusts from 0.7 psi (1.6 feet water) to 10.3 psi (23.8 feet water) using a graduated knob. Water by-pass capacity is 1.2–9 gpm. See Hydronic Accessories for ordering information.

CazzBrass™ Manifolds All CazzBrass Manifolds are 1-1/4” diameter cast brass, and available in 3- and 4-branch sections. Each section is fitted with one “union” for easy assembly to a second section, Manifold End Plug, or Vent-and-Purge Assembly. Circuit (branch) outlets are threaded for connection to T20 Compression Fittings. Manifold trunk outlet/inlet is 1-1/4” straight thread; order two Transitional Fittings per manifold pair. Manifolds are supplied as individual units (not pairs) for assembly in the field. Factory-assembly is available with manifold pairs mounted to brackets. Please note, only CazzBrass style fittings are compatible with CazzBrass manifolds. Do not use SS-T20 style fittings. See Onix or RadiantPEX sections for fittings. RadiantPEX-AL fittings are not compatible with CazzBrass manifolds.

Custom Tubular Manifolds Watts Radiant Custom Tubular Manifolds are manufactured to project specifications. All trunks are made of copper; all fittings and ball valves are brass. Every manifold is pressure tested before leaving the factory. Manifolds are available in 1”–6” ID trunk sizes. 1”, 1-1/4”, 1-1/2”, and 2” sizes are in this catalog. Call for pricing on larger manifolds. They are built in ready-to-install pairs: one supply manifold and one return manifold. Three styles are available:

Standard — no mini ball valves

•Standard — no mini ball valves •BVR — mini ball valves on the return manifold •BVSR — mini ball valves on supply and return manifolds

Five fitting styles are available: •Onix •PEX Crimp •RadiantPEX-AL Press •RadiantPEX-AL Compression •T20 (for Onix, PEX, and RadiantPEX-AL)

BVR — pair with ball valves on return

Approximate flow rates for Tubular Manifolds: •1” trunk up to 12 gpm •1-1/4” trunk up to 20 gpm •1-1/2” trunk up to 32 gpm •2” trunk up to 60 gpm

BVSR — pair with ball valves on supply and return

Onix, Crimp, and Compression manifold barbs are all spaced at 2” on center. RadiantPEX-AL Press barbs are spaced at 2.5" on center.

* How to Order: The number of circuits served by the manifold pair determines the last two

digits of the item number, as well as the List Price. For example, a 3/4” Compression Custom Tubular Manifold pair with five circuits is Model Number RLC155505. To price this same manifold pair, multiply the number of circuits (5) by the cost per circuit to arrive at the list price.

How to Order:  The number of circuits served by the manifold pair determines the last two digits of the Model Number, as well as the List Price. For example, a T20 Custom Tubular Manifold pair for five circuits is Model Number PX154505. To price this same manifold pair, multiply the number of circuits (5) by the cost per circuit to arrive at the list price.

CustomCut™ Manifolds CustomCut Manifolds are designed for flexibility at the wholesale and the installation level. They come in 4-ft.-long copper “sticks” to be cut to length in the field — cut off five branches for a 5-branch manifold, seven branches for a 7branch manifold, and so on. You can stock just a few types and have everything you need. CustomCuts are made in various styles: • with Brass fittings: Onix, PEX Crimp, RadiantPEX-AL Press, RadiantPEX-AL Compression, and T20 Compression. • with 1/2” and 3/4” Copper Stubs, for attaching standard ball valves or Female copper sweat fittings in the field. • with 1/2” Brass Base Branches, for attaching Watts Radiant 1/2" male sweat fittings or Mini Ball Valves in the field. CustomCuts are made with branches spaced at 3" or 4" on center, depending on the type of manifold. They are available with and without Mini Ball Valves (MBVs). Larger diameter trunks can be ordered as well. CustomCuts are priced and sold as a single manifold, not in pairs.

Swedged Manifolds Swedged Manifolds are easy to stock and easy to assemble. These 1” copper manifolds are swedged at one end to sweat to each other or to 1” copper pipe. Solder a 2-branch to a 3-branch to make a 5-branch, a 3-branch and 4-branch to make a 7-branch, etc. Four fitting styles are available: Onix, PEX Crimp, RadiantPEX-AL Press, and RadiantPEX-AL Compression. Swedged Manifolds are sold individually, with or without Mini Ball Valves (MBVs).
