This propane gas cylinder features the new industry standard LCC27 system that is safer and easier to use than the current POL cylinder connection. The new LCC27 cylinder will allow connection of the new LCC27 appliance connection as well as the POL appliance connection. The new LCC27 cylinder connection incorporates a “back check valve” which, if the appliance connection is not tightened fully, will not disengage and allow gas to flow. Gasmate Safe Lok cylinders feature a black coloured cylinder valve hand wheel to easily identify them from existing POL cylinders. A handy portable gas cylinder from Gasmate that makes outdoor activities simple and easy. It is suitable for outdoor heaters, barbecues and stoves, camping and caravan, boating and is suitable for use with most products that have either the new LCC27 appliance connection or POL appliance connection.
