yep should, i had the very same manual mate for my old maxy

[JSC_Liason_neo]

The things is that when it is turn off, air still comes out, so the on/off doesnt work

[i8dafrog]

Mate u just need to replace one or mabey both orings in the on off.

most likely the small o-ring in the block of the reg, not actually around the on-off shaft. You'll need a small allen key or a pick of some sort.


Get the on-off shaft out, look straight down the hole and on the side closest to the bottle near the bottom of the hole you will see a small o-ring. Pull that o-ring out, and if there's a little nick taken out of it, thats your problem. You can get away with rotating it rather than replacing it if you get stuck: if you don't have a replacement o-ring, rotating it 180 degrees before re-seating should fix the problem.


I find the usual cause of this is opening the on-off when your tank is pressurized and the reg is not connected to your marker. These o-rings get chewed pretty quickly by doing this.
