I meet many buyers who struggle to choose a reliable gas manifold supplier in China. I understand this pain well, because I worked almost 20 years in the brass fittings and valves field and helped many clients avoid sourcing failures.
A gas manifold safely distributes gas from one or more sources to multiple outlets. It controls flow, stabilizes pressure, and keeps the gas system running without interruption.
I write this full guide to help you source confidently in 2026.
What is the function for Gas Manifold？
Gas Manifolds Installation
Many buyers misunderstand the real job of a gas manifold. Some of my early clients used the wrong type of manifold and faced leaks, unstable pressure, and failed inspections. I never want you to repeat these mistakes.
A gas manifold connects one or more gas cylinders or gas pipelines, and it distributes the gas to multiple outlets in a safe and controlled way. It also helps switch between gas sources, balance pressure, and reduce downtime. This is why hospitals, commercial buildings, labs, and industrial plants all rely on manifolds.
A good manifold protects the entire gas system. A poor one creates long-term risks, high repair costs, and safety concerns.
Why this matters for real buyers
I had a client from Canada whose system had constant leaks because his supplier used low-grade brass for the manifold body. After switching to a compliant and certified factory, all issues disappeared. This experience reminds me that a gas manifold is not a simple part. It is a safety device.

What Standards and Certificates for the Gas Manifolds？
Gas Manifolds Standard
Most new buyers only check the price and delivery time. But after nearly 20 years in this field, I always check certifications first. Gas systems follow strict rules. A missing certificate can stop your shipment at customs or fail local inspection.
Gas manifold standards fall into three main groups:
material & piping standards, medical gas standards, and factory quality certifications.
1. Material & System Standards (PEX-AL-PEX and Brass Gas Manifolds)
| Standard | Use |
|---|---|
| ISO 17484-1 | Global standard for PEX-AL-PEX multilayer gas piping |
| AS 4176.8 | Australian multilayer gas pipe standard |
| CSA B137.5 | Canadian PEX piping and fittings |
| EN 331 | Gas valves and brass fitting requirements |
| ASTM F1960 / F2159 | US PEX fittings and manifold standards |
These are essential for building-gas systems in many countries.
2. Medical Gas Manifold Standards
| Standard | For |
|---|---|
| ISO 7396-1 | Medical gas pipeline systems |
| GB 50751-2012 | China hospital central gas pipeline code |
| CE — Medical Directive | European compliance for medical equipment |
| HTM 02-01 | UK healthcare gas guideline |
Medical manifolds must meet much stricter purity and leak-rate requirements.
3. Factory Quality Certifications
| Certificate | Meaning |
|---|---|
| ISO 9001 | Quality management system |
| ISO 13485 | Medical device manufacturing system |
| CE Marking | European safety compliance |
| SGS / TUV Reports | Pressure test, brass composition, leak test |
| ISO 45001 | Occupational health & safety |
| ISO/IEC 27001 | For digital monitoring modules |
I suggest buyers always check whether the supplier has passed third-party pressure tests and material testing, especially for brass manifolds.
How to Evaluate Gas-Manifold Suppliers
1. Verify test reports
To request pressure test reports, material composition analysis (especially brass), and leak-test certificates.
2.Drawings and Samples
Drawings and Samples is very important for the gas manifolds,you can check whether the supplier can make the drawings and make the samples according to the drawings diamentions.
3.Evaluate after-sales
How quickly can they ship spare parts? Is there local support? For critical systems like gas manifolds, downtime is unacceptable.
The right gas manifold supplier gives you safety, stability, and long-term value. For more details, welcome to contact us.
