Broken on/off knob

[july_favre]

the metal piece inside the rubber knob on my valve broke. Can I replace the part myself, and where would I get that piece?

Is the cylinder empty?

How did the "piece" break?

Sounds like you should take this to an equipment service specialist.

You may be in need of a new valve.

Good luck,

Have some one who is look at it. It might call for a valve rebuild.

What brand is the valve?
What metal piece is broken?

 

[july_favre]

I dont know the brand off the top of my head. The square rod that the screw screws into was broken.

 

[Uncle Pug]

...is there enough sticking out of the valve body that you could graps it with pliers?

 

[july_favre]

No, its about 1cm inside.

The valve will need to be repaired or replaced and you will probably need to to take it into the shop to have them bleed any pressure off rather than try to do it yourself.

Sounds like you may only have sheared a valve stem. If your shop will sell you a new stem, then yes you can fix it your self. You won't need to bleed the tank to do this and YOU WILL NOT NEED A NEW VALVE. Any one who tells you otherwise is misinformed or trying to rip you off.

The method of knob shear may have damaged the valve elsewhere. I agree that for a simple bent or broken stem a valve replacement is not usually necessary. The other side of this is that anything striking the vlave with enough energy to snap a stem will probably have damaged the packing nut and/or stem neck as well.

I keep a few spare stems in my Save-a-dive kit, but i have been accused of being a bit anal when it comes to filling that kit. Your LDS should have the parts, or be able to gt them rather quickly. As a rule shops stock valves and the parts normally replaced during service. Stems and packing nuts may not be on the repair bench parts list, so the shop may offer a replacement valve instead.
