Jiangsu Easywell Smart Products Co., Ltd. presents a high-performance range of in-line manifolds, engineered to optimize fluid distribution in industrial, commercial, and HVAC systems.
As a compact extension of Easywell’s hydronic control solutions, these manifolds — including premium carbon steel and durable steel models — are designed to deliver precise flow control, pressure balance, and seamless integration with various heating, cooling, and water circulation systems.
These in-line manifolds are the perfect solution for retrofit projects, wall-mounted boilers, modular HVAC systems, or tight mechanical rooms where space and performance matter most.
Crafted from high-grade carbon steel, stainless steel, or brass, Easywell’s in-line manifolds ensure exceptional durability, corrosion resistance, and flow stability.
Each manifold undergoes precision machining to provide smooth internal flow paths, minimizing turbulence and improving energy efficiency.
| Material | Key Features | Typical Application |
|---|---|---|
| Carbon Steel | Heavy-duty design, pressure-resistant, corrosion-treated finish | Industrial boilers, district heating, high-flow HVAC systems |
| Steel (Standard) | Cost-effective, reliable performance, quick installation | Commercial and residential heating systems |
| Stainless Steel | Maximum corrosion resistance, hygienic surface | Marine, food processing, and humid environments |
Carbon steel manifolds deliver superior performance in demanding applications,
while standard steel models are ideal for general HVAC or plumbing installations.

Step 1. Preparation
Check all ports for debris or thread damage.
Confirm circuit count and pipe diameter with the system design.
Step 2. Mounting
Secure the manifold horizontally with M8–M10 anchors.
Ensure level positioning for even pressure distribution.
Step 3. Connection
Apply PTFE tape or anaerobic sealant to all threads.
Tighten fittings without over-torquing; use wrench support.
Step 4. Pressure Test
Test at 1.5× working pressure for at least 30 minutes.
Inspect all joints for leaks.
Step 5. Balancing
Open each circuit valve halfway; fine-tune using flow meters after filling the system.
1️⃣ Determine Flow & Circuit Requirements
– Identify how many branches or loops you need (typically 2–8).
2️⃣ Define Your Application
– Heating → carbon steel or stainless steel.
– Cooling → stainless or brass for anti-condensation performance.
3️⃣ Assess Installation Space
– Choose in-line manifolds for wall or cabinet layouts.
4️⃣ Material Selection
– Stainless for corrosion resistance, carbon steel for strength, brass for small systems.
5️⃣ Integration Level
– Select pre-assembled kits for faster installation.
Easywell engineers can help you configure a tailored manifold solution to match your hydronic system design.
| Issue | Cause | Solution |
|---|---|---|
