Default regulator problem

My torch has been sitting up for a long time. Maybe 10-15 years, can't remember the last time I used it. I turned the oxygen on and the gauge after the regulator pegs all the way and oxygen sprays out of the weephole in the regulator. could the diaphram be torn or something stuck? And can it be serviced?

Diaphragm blew out, happened, yes they can be rebuilt, generally I just
disassemble them and sort out the parts I need, and rebuild it myself.

They are easy and anymore the cost of sending them out for a rebuild is
close to the cost a buying a new one.

My LWS, SJ Smith is great on getting me parts.

If you do it yourself disassemble slowly, take a lot of pictures and note on how it came apart so you can get every back together the same way.

Easy but tedious, got slow and you will have many years of service.

One thing that Shade forgot to mention is to use no grease, solvent, etc of any kind unless it's oxygen safe. Don't need to read about you in the papers.

+1 On That.....

Also if they need cleaning and you can't clean with Scotch Brite's do not sandblast.... you should only use baking soda blast media...
if you have a blaster for that media... or the adapter for your regular blaster to use the soda media...

I don't include that information to assist with natural selection...

It looks like what is bad is an o-ring on the poppet assy. I can only find the whole poppet assy for $39. Can I just find an o-ring that will fit?

Measure the o-ring OD and the cross section diameter, then google o-rings.
You will likely have to buy 100 of them for $1.99 and $5 shipping.

Ace Hardware has drawers full of O-rings.

I've rebuilt a couple pairs of regulators in the past. Got a "kit" from a Debay vendor--I forget who. Just do a search of your model number and scoll the listings. I think I paid less than $15 a kit to my door. Depending on the regulator, the part that went bad on mine was the "poppet" I guess you could call it. A little valve acted on by the adjustment "T" or knob and not serviceable with my regulators.

This is another reason why you ALWAYS ease the tank valves open and watch the low pressure gauge. If the regulator is bad, and pegs your low gauge, you shut off immediately and fix. The high pressure can damage your gauge, hoses and torch...

Liquid acetylene will toast a regulator, BTW. Plus it can be explosive under the right conditions. That is why we let an acetylene cylinder "settle" upright after transport laying down. At least 12 hours but 24 is better... So only gas flows through the regulator.
