Never run out of gas again with the Gaslow 500 Automatic Changeover Head, designed for twin-cylinder LPG systems in caravans, campervans and motorhomes. This clever device automatically switches from your main (service) cylinder to the reserve cylinder when gas runs low, so your supply stays uninterrupted and your appliances keep running smoothly.
It fits any post-2004 30mbar regulator with a W20 inlet, for an instant upgrade in convenience and safety. The easy-view colour indicator shows green when drawing from the service cylinder and red when switched to the reserve, so you always know your gas status at a glance.
Built with safety in mind, the integrated non-return valve lets you replace an empty cylinder without shutting off your gas system — perfect for off-grid touring, winter use and extended stays.
