Every gas stove installer faces the same task sooner or later: converting a stove from LPG to natural gas, or the reverse. The change is simple in principle — swap the nozzles — but getting the aperture right is where mistakes happen. Here is a practical conversion chart and the logic behind it.
LPG (propane and butane) is stored as a liquid and delivered at high pressure, typically around 30 mbar in many markets. Natural gas arrives through a pipeline at a much lower pressure, often around 20 mbar. To deliver the same heat output, a nozzle must flow more gas volume at low pressure than at high pressure — which means a larger aperture for natural gas and a smaller aperture for LPG.
As a rule of thumb, converting a burner from LPG to natural gas means stepping up roughly 0.15–0.25mm in aperture, depending on burner size and gas pressure. Always confirm against the appliance manufacturer's specification. The full range below covers the common conversion window:
Our entire nozzle range — 16 aperture sizes from 0.45mm to 1.35mm — shares a unified M6x0.75 thread. That single standard means one wrench, one thread gauge, and interchangeable nozzles across the whole SABAF-compatible ecosystem. For a distributor, it means stocking fewer variants to serve more conversions.
Wholesalers who stock the complete 0.45–1.35mm range can serve both the LPG market and the natural-gas market — and every conversion job in between. THREEMI supplies the full range factory-direct at wholesale prices, with flexible carton MOQ. Keep both gas-type columns of the chart in stock and become the conversion source for your region.
