Cylinder Selection
Begin with gas service, application, required capacity, pressure and destination. The product family and model should follow these confirmed inputs.

Confirm the right inputs before selecting a model.
A concise procurement guide for comparing product options and preparing a clearer enquiry. Product-specific values remain on the relevant category and model pages.
Capacity & Working Pressure
Water capacity and gas capacity are not interchangeable. Confirm the required unit and select working pressure only from available models.
Gas Service
Gas compatibility affects cylinder material, cleanliness, valve, marking and transport. State the exact gas or mixture when requesting a quotation.
Valve & Connection
Confirm the cylinder inlet thread, outlet connection, gas service and pressure together. Market conventions alone are not enough to select a valve.
Applicable Standards
ISO, DOT, EN-TPED and GB options vary by product and model. Identify the destination requirement before the final model is confirmed.
Cylinder Marking & Colour
Colour and permanent marking requirements vary by market and gas service. Provide any mandatory wording, logo or colour reference with the order.
Packing & Container Loading
Packing depends on cylinder size, valve or cap arrangement and handling needs. Loading quantity is confirmed against the final packed dimensions.
Gas Transport Considerations
Filled gases are subject to gas-specific dangerous-goods, packaging, quantity, route and destination requirements. Availability must be checked before shipment planning.
