Good day.

As in the topic, i have question about scba cylinder.

I am on board and one my bottle has broken threat on this plactic valve knob(turning, but dont open the bottle). I removed it. But now when i put new(some how we had from servis a spare one) it cannot fit. When i assemble it back (plastic washer and spring) the threat is not long enough and i cant catch threat with nut.

Without spring i can fit it and operate the bottle.

Type of bottle honeywell fenzi

if it matter bottle has pressure inside 250. bottle is 300 bar.

Any advice?
