Plumbing distributors and importers often struggle to identify truly reliable brass PEX manifold suppliers among so many flashy claims.
Here is an updated 2025 list of the top 10 brass PEX manifold manufacturers in the world, based on product quality, pricing, production capability, and global customer reputation.
Choosing the right brass manifold supplier impacts not only your inventory cost but also your project schedule. Let’s explore the leading players and help you source smarter in 2025.
What is Brass Pex Manifolds?
Brass Pex Manifolds Different Types
Many new plumbing buyers feel confused when trying to choose the right manifold system for their PEX projects.
Brass PEX manifolds are plumbing distribution devices that control the flow of water or other fluids from a central source to multiple outlets through PEX tubing.
They are mainly used in radiant floor heating, domestic plumbing systems, and some commercial applications. The brass material ensures higher durability and pressure resistance compared to plastic types.
Why use brass instead of plastic?
The most common alternatives to brass manifolds are plastic (usually PPSU) manifolds. However, brass manifolds offer:
- Higher temperature and pressure tolerance
- Better mechanical strength
- Longer lifespan
- Easier connection with brass fittings
- More trust in regions with strict plumbing codes
Typical applications
| Application | Description |
|---|---|
| Radiant Floor Heating | Distributes hot water to various zones |
| Potable Plumbing Lines | Delivers water to kitchens, baths |
| Commercial Buildings | Multi-branch water supply control |
Depending on the setup, brass PEX manifolds come with different numbers of ports (2 to 12 outlets), often with built-in valves, gauges, or flow meters.
How does it work?
A brass manifold has a main inlet (or two) and multiple outlet ports. You connect the PEX pipe from each port to fixtures or underfloor loops. Shut-off valves on each port let you isolate zones during maintenance or control flow independently.

What makes a good brass manifold manufacturer?
When sourcing from China or Europe, I always look at the following:
✅ Product Quality
Use of CW617N brass, leak testing, polished surface treatment, and reliable sealing structures.
✅ Certifications
WRAS, NSF, ACS, DVGW – especially important for EU and North American markets.
✅ Production Capacity
Can they produce 50,000 pcs/month without lead time fluctuation?
✅ Engineering Support
Do they offer samples, drawings, and new design support for OEM/ODM?
Many importers underestimate the need for tech support when ordering custom manifold configurations. But in my experience, suppliers who can adapt fast to custom needs are far more valuable than ones with only catalog products.
How Many Types of Pex Manifolds?
Type of PEX Manifolds
There’s often confusion between different PEX manifold types—some buyers mix them up and end up ordering the wrong version.
There are mainly three types of PEX manifolds1: open-loop manifolds2, closed-loop manifolds, and flow-meter manifolds. They can be made of brass, plastic, or stainless steel.
Each type serves different project needs and installation preferences. Here’s a simplified breakdown.
🔍 Classification by Design
| Type | Use Case | Material Options |
|---|---|---|
| Open-loop | Potable water, plumbing | Brass, PPSU |
| Closed-loop | Heating loops, zone control | Brass, Stainless |
| Flow-meter manifold | Radiant heating, balancing loops | Brass, Stainless |
🔧 Common Port Sizes & Configurations
Most brass PEX manifolds follow a modular format:
- Inlet: 1" or 3/4" Female Thread
- Outlet: 1/2" PEX (or 3/8" on request)
- Port Count: 2 to 12
- Optional: shut-off valve, drain valve, thermometer, air vent
💡 Buying Tip
Some suppliers label their manifolds with port count only, not total configuration. So "6-port" might be 3+3, 6+0, or 2+4. Always confirm the detailed drawing with your supplier.
🔄 OEM/ODM Flexibility
For distributors planning private label lines, this is a key section. A flexible manifold partner should offer:
- Custom logo laser marking
- Alternative ball valve handle colors
- Customized port layout (left-right symmetry, offset designs)
- Optional kits (brackets, adaptors, clamps)
At VPEXCO, we help many clients develop tailor-fit manifold sets for their local markets, including full kits with hoses, adaptors, and even packaging.
This 2025 list helps you find brass PEX manifold suppliers with the right mix of quality, flexibility, and price for your projects.
