Worldwide there are several different types of valve connections for propane, butane and LPG containers. Often there are different standards even per country, no matter whether gas cylinders are used in the leisure sector for barbecues, in campers or in industry as propellant.

Below we have compiled an overview of the valve connections available worldwide.

On request, we can supply all the valves listed below individually or pre-assembled on composite, aluminium or steel gas cylinders.
