The problem – This usually happens when you first turn on the air, if you haven’t tightened the yoke enough. With the seat loose, pressure forces the O-ring to squeeze through the gap and tear, causing a loud escape of air. Another cause is using the wrong-size O-ring.
How tight should a scuba tank valve be?

How do you stop a CO2 tank from leaking?
CO2 LEAK PREVENTION TIPS

Why should I not turn off a dive computer between dives?
Don’t turn your computer off between dives. Most won’t let you, but if you take out the battery or shut the computer down, it loses its memory of your previous dives and your residual nitrogen. You’ll have to allow all residual nitrogen to leave your body before resuming use of the computer.
Is it OK to dive with a leaking pressure gauge?
– If it’s the high-pressure hose to the SPG, it will be a small leak. As long as it doesn’t seem to affect the gauge, you can probably continue the dive. The high-pressure hose leak looks dramatic but involves very little air — the orifices are tiny.
Is it safe to dive with a leaking pressure hose?
As long as it doesn’t seem to affect the gauge, you can probably continue the dive. The high-pressure hose leak looks dramatic but involves very little air — the orifices are tiny. A low-pressure hose actually leaks more air, but you will still have time to return to the surface calmly and deal with it.
Why is there a leak in my hose?
A leak immediately after an overhaul probably means the tech has not tightened the hose enough. If very loose, the O-ring can blow out with sound effects as above. The fix – Also as above. Where there is a swivel on the hose, be sure to separate between the swivel nut and the next nut, not between the two nuts and the SPG or second stage.
Why is my 2nd stage purge valve not sealing?
The problem – Sand, grit or corrosion under the second stage valve seat prevents it from sealing. The fix – Swirl the second stage through the water while working the purge (tank pressure must be on). The sand or grit may be washed out. Back on the boat, you may be able to remove the purge cover for better cleaning.
