Which are the lightest 2L Cylinders

iratnl · 3rd April 2007, 09:19

I'm looking to get a pair of 2L Cylinders for my KISS Sport; primarily for travelling - so I'm looking for the lightest ones; which are lighter, Steel or Alloy. I've heard that the thicker walls of the Ally make them heavier than the steels - but whenever I've held a 2L Luxfer, it sure feels lighter than a 2L faber !

The lightest 2L cylinders suitable for O2 are SCI: carbon filament on Ali, 300 bar, O2 rated and given the cost of RBs accessories, are affordable. I have one in my hand. They have an 18mm thread.

Anyone know of any company that makes a 300 bar DIN SCUBA cylinder valve that has an 18mm thread? Getting 25mm valves turned down to 18mm and replated is a pain.

Have a look at Tecme's website, Martin has nice used ali/carbon 2l tanks, 2,2kg with the valve. I use them on my rEvo. ;)

Tank thread is small conical. The valve is O2 German standard but Martin can put standard G5/8 DIN instead.
Have a look:

SCI are the way to go as they are easily accessible, there are some nicer cylinders out there but military only i'm afraid...

Alex et al,

T.D. Preece in Australia do a large variety of different spec valves for scuba, be it military or regular. They have a number of M18 valves depending on the orientation you want.
