How to Identify a Gas Cylinder Valve for Replacement

A practical starting point for collecting the information needed for an initial technical review.

Start with the existing valve

The fastest route to a useful answer is a clear record of what is already installed. Photograph the valve from two or three angles in good light, including any markings stamped on the body.

  • A straight-on view of the outlet connection
  • A view showing the inlet thread where it enters the cylinder
  • A close-up of any stamped markings or codes

Confirm the gas and the application

The gas determines much of the specification. Record the gas, its typical working pressure, and whether the cylinder is used for filling, distribution or end use. If the cylinder handles more than one gas over its life, note that too.

Record the connection information

Inlet thread and outlet connection are the two details that most often decide whether a valve fits. If the standard is not stamped on the valve, record the physical measurements you can take and say they are measurements rather than a confirmed standard.

Share what you know

Incomplete information is still useful. A photo with two unknown fields is more actionable than a guess presented as fact. Our team reviews what you send and comes back with an initial matching recommendation.

Before you contact us

  • · A clear photo of the existing valve
  • · The gas and its typical working pressure
  • · Inlet thread and outlet connection, if known
  • · The country the valve will be used in

Final compatibility and regulatory suitability require technical confirmation.
