BTS steel scuba cylinders from 1 to 20 litres, supplied with the valve you need.

Steel cylinders carry more gas for their size than aluminium and sit negative in the water, which means less lead on your belt. Our BTS range runs from small 1 to 3 litre cylinders for pony and inflation use, through 7, 8.5 and 12 litre singles for everyday diving, up to 15, 18 and 20 litre cylinders for long and deep dives. Choose 232 or 300 bar, a DIN or M26 valve, left or right handed outlets, a second outlet for a pony regulator, or nitrox and rebreather valves, with flat bottom options that stand upright without a boot.

Trade and public orders welcome, with fast UK and worldwide shipping.
