I'll start worrying

if he startes asking about nitric acid......

kevin_5

I dunno,

Much about it except I think you can get it from medical supply houses. Or wherever they make glycerin filled guages. How about a web search? Kevin

I use glycerin

to clean the door seal gaskets and other rubber pts on my old cars. You can get it in small (4 oz)bottles at CVS/Walgreens

Matt Undy

how pure?

you can get lab and drug grades from chemical supply houses. Here is one such house:

Here is the search I used to find it:

http://froogle.google.com/froogle?q=glycerine+-soap+usp

The stuff from mcmaster is much less expensive, but it isn't anhydrus/200 proof which is probaly fine for your uses. My guess is that you mean by pure that it isn't combined in some other product such as KY. I'm not sureabout its ability to support bacteria, if you are trying to refill a damped gauge or something there may be some preservatives in the fluid in those.

They keep that stuff locked up tight. I wouldn't feel right "borrowing" it anyway - even with permission. Mad Dog

I think...

he's implying that you'd be attempting to make nitro-glycerin. Great stuff for heart attack victims!

Larry has the ticket. 111.21$ a 5 gal bucket:)

hey cant go wrong:) and if you have a japanese car with a hydraulic clutch....one spoon ful....no more sticking shifter in cold weather:)m oh dont put any in the breaks cylinder. even though it may make them work you have a heat thing going on that may or may not cause them to catch on fire so i was told by old indians:) i must say that i put some in the master cylinder anyway and dumped the system when the temp came up to -30¡ãF. just lucky i guess.

When I was a kid in the sixties the Water Dept put it in fire hydrants in the winter. Don't know if they still do that but your local water dept may know where to get it.

say - mad dog, i hope

you made sure that no part of you sprinkler system can freeze in the winter- it's a common problem be cause the water is stationary - and unless a low part of the system is exposed to house air – so it can convect the btu’s to the extremities – you could be in trouble – that’s why people spend lots of money on those dry-instant-fill-on-pressure-drop systems – I am still waiting for the pex sprinkler people to do a dry system – need real gas tight connectors

Mad Dog

I hear ya

I thought of doing a DRY SYSTEM, but it would be overkill for my house...besides the air compressor would get annoying. I had Mark Bromann Fire Sprinkler Engineer design the system for me to be simple. He writes in PM Engineer every month. Being a plumber first, I learned to always insulate ANY piping that could be subject to freezing temperatures. I insulated the HECK out of the few spots that could ever give me trouble, but I am filling the whole system with antifreeze as well - for good measure. Mad Dog

Thanks Drew and Leo

I am still considering using the PG Firefighter, but am concerned about toxicity. The system has an RPZ on it, but I always prefer to use natural- non-toxic products if I can. Pure Glycerine seems that it may be less expensive as well. Can you give me the advantages of your product over Glycerine? Thanks, Mad Dog

what about solution separation

after extended periods of time, might it not drop out of solution (I am not saying it does – just ignorant of the facts), cause if it does, then, you need to put electric heat tape on the bottom and run it periodically to cause convective circulation to mix it up again - might not be a bad idea to do it anyway - they sell the plug-in types at the HOME-DEsPOT for about 20$ - put it on a timer for 1/5 hr at 5am - the coldest time on avg - to maximize the convective effect – and you only need the show plugged from October to April - you couldn’t care less about the solution after that

Glycerine Purity

Mr. Dog, if I may call you that,

Take a look at our website, www.noblecompany.com . It will give all the non-toxicity information about our product.

Other considerations are; Pure glycerine has a freeze temp of around 57 degrees F. It doesn't really freeze it crystallizes.

Mixing glycerine yourself is a hit or miss proposition. It takes an extreme amount of turbulation to make sure it is mixed properly.

There are another half dozen reasons you shouldn't do this yourself but this would probably bore you.

Just one question. Would you try to mix your own brake fluid for your family vehicle?

I heard this somewhere. Trust the professionals.

Excuse me; I must get down from my soapbox before I fall.

Mad Dog

I believe if it is mixed properly...............................

It will hold up. Its potency will be checked every few years and complete replacement every 7-10 years. Mad Dog

The only reason

we used glycerin was it's compatability with the PVC Blazemaster pipe we installed. Glycols cannot be used in PVC or CPVC pipe.


Regular propylene glycol is accepted and compatiable with copper or iron pipe systems. A RPZ should meet most codes for seperation, although most PG is considered low oral toxicity and would only need a backflow check as per most codes. I'd still go with a RPZ.

The glycerin I have was supplied by Pacfic Fire Supply that also sold the PVV sprinkler pipe. I'm not sure how you dilute or check freeze protection on glycerined systems. I recall we needed a gear pump to install the stuff in cold weather.

A sprinkler system should not have O2 ingress issues like non barrier radiant systems, and the fluid should last a long time under these conditions, I would think

Yes, this is what Mark Bromann told me as well

I know Pg would be fine, but I always feel better using non-toxic, glycerine. From the pricing I've done so far, it seems that the equivalent amount of Pg is double the price of glycerine. Safer and cheaper. Mad Dog
