<div dir="ltr"><div>Hi All,</div><div> </div><div>Ive got a 10 litre aluminium scuba tank fitted outside my sub that carries 100% O2. The system has a scuba regulator 1st stage that drops the pressure to ambient. There is also an overpressure relief valve set to 14 bar. The entire system is new and has been O2 cleaned.</div>
<div> </div><div>I was led to believe by the shop I got it from that the aluminium cylinder was fine for 100% O2 service. </div><div> </div><div>However, doing a bit more research, im now not convinced the alu cylinder is safe. There seems to be a lot of conflicting evidence, depending on what you read.</div>
<div> </div><div>Does anyone have any thoughts, advice before I go and change the tank for a 10L steel O2 clean one?</div><div><br />Many thanks</div><div>James</div></div>
