Re: [MBZ] Test Refrigerant

Iirc Jim Cathy said it's "wet" which made it unsuitable for use in AC systems. I've found the stuff in 20# cans to be oily which can clog up gas jets in heaters. We refill 1# cans for the Mr Heater at camp and about once a year I have to clean the jets... Curt Sent from Yahoo Mail on Android

Re: [MBZ] Test Refrigerant

I just noticed that they do not call it R-12A any longer. It’s R-134A. Probably some rule about not being to replace anything in an R-12 system. Jon > On Nov 27, 2016, at 11:21 AM, Mitch Haley via Mercedes > wrote: > > Commercial grade propane. > It's the highest

You can cook with HD10 but you really need HD5 for your forklift if you don't like gummy piston rings. http://www.propane101.com/propanegradesandquality.htm > On November 27, 2016 at 11:47 AM Curley McLain via Mercedes > wrote: > > > Is the kind they pump into your 20

Re: [MBZ] Test Refrigerant

Is the kind they pump into your 20 lb tank the same, or do they pawn off some low grade crap for BBQ grills and forklifts? I am guessing the tank exchange IS low grade crap. Mitch Haley via Mercedes November 27, 2016 at 10:21 AM Commercial grade propane. It's

Re: [MBZ] Test Refrigerant

Commercial grade propane. It's the highest common everyday grade (refrigerant grade R-290 isn't that common) In most states not named California, HD5 is the only grade that's legal for sale as home heating propane. Mitch. > On November 27, 2016 at 11:07 AM Floyd Thursby via Mercedes >

That's the advantage of Cathey Special Blend. If it leaks, just add propane until the pressures are good again. BTW, I was looking at Linde Gas this morning, and they claimed their R290 was 97.5% propane. Any reason why I should pay dollars per pound for 97% refrigerant grade when I get pounds

Re: [MBZ] Test Refrigerant

I have tried this and duracool and I just do not like the blends. If you have any sort of leak at all the different elements leak at different rates which changes the mix and it does not cool. You can't simply top it up you have to discharge and start all over. You may not have had a leak leak

Re: [MBZ] Test Refrigerant

I have also used it with excellent results! When the compressor blew on the 123 (totally unrelated to the ES-12) the mech used good AC parts from a recently wrecked 300CD and filled with R-12. That was in 2013, and I have not had to charge since. I had some cans left over, so Dimitri and I

I’ve used the Industrial 12a-6 in my W126 and it did a great job. My only complaint was having to buy a case of the stuff as it was far cheaper than just buying a few cans. Dan > On Nov 27, 2016, at 8:44 AM, Jon Agne via Mercedes > wrote: > > Hopefully this isn’t

Re: [MBZ] Test Refrigerant

What we're talking about here is Jim Cathey's homemade ES-12a, so you're right on topic. I think Kaleb used to buy ES until he got some cylinders of R-12. Mitch. > On November 27, 2016 at 8:44 AM Jon Agne via Mercedes > wrote: > > > Hopefully this isn’t too far OT, but

I don't pre-mix. You want ISO-butane. Sold as high-altitude camping fuel. If you could premix, I suspect you'd need to charge from the bottom of the bottle. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To

Re: [MBZ] Test Refrigerant

that is my guess. I don't know if you could safely pump it in with a vac pump. I'd guess you could pump it in with an old refrigerator compressor with refrig valves soldered on. Jim is the guru of test refrig. Maybe he'll tell us. Floyd Thursby via Mercedes

Re: [MBZ] Test Refrigerant

The better camping gas has iso-butane in it. Butane is a bit low in the vapor pressure department for diluting propane refrigerant. It doesn't even make decent lighter fuel in cold weather unless you carry it in a warm pocket. Mitch. ___

Re: [MBZ] Test Refrigerant

How would it work? Would the pressures allow the butane to flash into the propane tank, or to run in as a liquid? Start off with an empty propane tank then get the butane in there, then add the proper amount of propane? --FT (no gas tables at hand at the moment) On 11/26/16 11:23 AM,

Re: [MBZ] Test Refrigerant

Well, I made a side-tapper out of a regular R12 tap, a coathanger, and two vise-grips. (Cut coathanger wire to length and twist two loops on the ends, and use the vise grips to clamp the loops together thus trapping the can tap against the can. One on each side. There, now it won't go anywhere

You need R12 gauges, a vacuum pump (if you want to really do it right), a side-tapper or else a fitting taken from a thrift-shop camping stove like I did, a propane torch, and some junkyard fittings and hoses. I'm being deliberately a bit vague, in that if you're not confidant in your ability to
