Oxygen regulator substitute

[Franklin Sankar]

Anyone tried to use a low pressure propane regulator to regulate oxygen?

Oxygen kit has to be “oxygen clean” on the inside which involves a lot of solvent. Otherwise any oil etc evaporates into the oxygen and you get a flash back BOOM!

Also I think the seals are made of oxygen resistant materials, and the propane threading should be backwards.

A very, very, very bad idea. Others have already mentioned O2 cleaning for O2 service. It's critical.

I deal with O2 clean all the time with my rebreather in SCUBA diving. One tank is pure O2, the other air or other diluent. The unit blends 'nitrox' on my back while I dive.

I fill my own O2 tanks from commercial O2 "T" cylinders using a small air-powered booster. It boosts gas from as low as 200psi to 2400 psi using a standard compressor as 'drive gas'. I have boosted Helium as well as O2 (pure He does not affect O2 clean). The booster is O2 clean, as are all the fittings involved.

Even opening an O2 valve too quickly into an empty tank can generate enough heat to create an O2 fire. O2 fires are incredibly dangerous.

Using a propane regulator is to invite an O2 fire, and since the regulator is at a rather critical point in the whole O2 feed chain, an O2 fire at that point would be a really bad thing.

Can somebody who knows how to do it please start a go fund me account for the nicest glass guy in Trinidad?

Do you need an O2 regulator? I may have an extra one floating around.

You should meet Franklin. He just sent me Cocoa balls from Trini. Great for hot chocolate after plowing the place out.

[Franklin Sankar]

Thanks for the advice and kind words.
Kudos for the board. To its benefits We can add it help saves lives. Not only from poison/toxins you can now add, oxygen fires.
Lucky I asked here before doing it. I always check before I violate any code.
Thanks Brian I found one.

Oh me too! If it isn't a violation, I won't do it!

Actually Franklin has visited me- he was visiting his daughter in England and I invited him for a visit. He had a tight schedule but made it here 3 days- right Franklin?
We blew glass one day, and then drove around in southern Sweden looking at studios and factories a couple of days
By sheer coincidence when we were in the Kosta factory Bertil Vallien came in with his entourage and starting making cast heads
So Franklin got to meet him and shake hands - Franklin was like a pig in a mud bath
Franklin supplies me with good curry- there is a large minority of Indian ancestry in Trinidad

Most memorable trip. I can’t begin to describe all the beautiful emotions.
I was so lost in this big place but Michael is a wonderful host. Sometimes I get nightmares of finding myself alone in the middle of somewhere. 😳😁
Living in a small island does that.

My oxygen concentrator does no have anywhere to adjust the oxygen pressure from the concentrator. so I have to regulate the output. The regulator I got is for high pressure oxygen on the input side. Not sure if it will work because the output pressure from the concentrator is 15 psi. And I want to drop it to 10 psi. Wish I could use a resistor. 😀
My torch requires 10 psi max. So this is the best time to ask. You think 15 psi is ok. Working with gas has been a mystery fir me.

I would run it wide open with NO regulator

[Hugh Jenkins]

The product tanks in most oxygen concentrators have an output regulator that cuts the internal operating pressure down to medical delivery rates. the common setting is from 5 to 5.5 psi. They are quite adjustable and have no lubricants. Both flow volume and pressure have to be considered. You do need a regulator or a good needle valve with pressure gauge to have any repeatable settings for a torch or burner.

15 psi will work just fine.

Thanks Ted.
