propane regulators

Unread postAuthor: isban » Tue Feb 13, 2007 5:16 pm

I was wondering what kind of regulators everybody uses on their propane/mapp guns. Are they adjustable or set at a certain psi and where did you get yours. I've found a lot of different kinds and was just wondering what everyone else is using.

Air compressor regulators are not ment for gas. I've tried them, they leak . Some are non- releveing. Most purge air to regulate, hence the
smell/danger.
I got these Irwins on e-bay 26.$ w/shipping. They come w/60 lb. gauge,
I switched out to oil filled I had.
I got one today in the mail and started rigging after work. Valve on new
one came from Mcmasters 10.$ They deliver so quick!

Well you must have a fault regulator because all the ones I used for propane don't leak.

btw, last time I checked, propane and air are both gasses.

and that was an airflow regulator which I'm sure doesn't limit tank pressure but instead slows the air down.

As long as it's non-relieving
The gasgets are different
There is a reason why different regulators are are used for FLAMABLE gasses.

I have had experiences with several different air pressure regulators, and they all bleed air to regulate pressure. Either use a regulator designed for propane, or dont use one at all, and instead use a pressure guage mounted in the middle of your meter pipe. It will be cheaper and more convenient to use, as you will not have to worry about setting and adjusting a regulator, just closing a ball valve at the proper time.

Well I don't have much experience with metering propane for spud guns, but I can see how a bleeder valve could be just a tiny problem. I'd personally go for the pressure regulator in the meter pipe myself, makes you look smarter for knowing how to work it even though it requires minimal intelligence.

That requires you too focus on the pressure gauge which can get annoying. I would rather have everything in swift motion.

Well that's your opinion. I enjoy spinning random knobs and pushing big red buttons that are entirely pointless. It just makes you look smarter.

lol :lol: :lol: that was funny. When I was 4-6 I wanted to be like the cartoon sciencists always mixing thing and pushing button lol :lol: :lol: :lol: .

And I didnt think co2 regulators release preasure out of a port into the open air except thorough the gun so not all regulate leak air to regulate preasure

I like my regulator set so I don't have to look to shoot.
I tried the gauge in the middle ,it was hard to get exact .
I have the gun on a shoulder strap and bag of gb's on a strap too.
Don't have to put the gun down to shoot, load + shoot.
