AP Valves Pony Cylinder Cambands

AP Valves Pony Cylinder Cambands are an extremely neat and secure method of mounting 2 or 3 litre pony cylinders alongside your main cylinder.

The pony band can either be used as a replacement for the standard AP BCD camband by threading the pony bands through the camband slots of any AP BCD backpack (fits pre and post 2007 BCD ranges) or alternatively, it can be simply cammed directly onto any main cylinder as shown.
