Tare weight

Postby forestg » Mon Jun 11, 2007 2:31 pm

Does anyone know what the tare weight is on 30# cylinders of R-12 or if it is marked on the cylinder where to find it?
Thanks,
Forest

I think it's 5lbs and a little for the box. I recall either seeing it marded TW =? on some but just looked at a Johensens 134a and it was not marked. I may have just weighed the dang thing for 12 but I don't have an empty one right now to double check and I won't take it out as it's my last sealed real Dupont Freon which will probably become a collector's item!!

i actually got lucky a few weeks ago. Me and my business partner bought out an old refrigeration company and with it came all of their stock parts that they had in their shop.

I found a skid of real DuPont -R12 freon. There are 9 full 30# drums and 4 50# drums here and several partials. Needless to say once the partials are gone i'm going to go back to using MP39 in my older refrigeration applications.


I just went and weighed an empty 30# drum for you, the tare weight without the box is exactly 5 pounds.

Thanks, I weighed one of my empties and it weighed 5 lbs 3 oz. I didn't know if they were all the same or not. The reason I asked is that I just purchased a supposedly full 30# and it weighs 27 lbs gross. If I deduct 5 lbs for tare then I only have 22 lbs of R-12. Seller maintains that none was ever used but container was not sealed so I don't know how he can be so sure in light of the total weight of the received container. He says maybe it leaked some in transit but if that were the case all of it would be gone.

BULL POOP!! That's a plain rip off! I knew they were 5lbs TW and the box could have weighed the little extra. Bet the cans don't all weight the same but surely not less than the net weight.

When a seal is missing or looks faked beware. My seals say the manufacture's name/logo in shrunk wrap and could never be reinstalled to look new.

Warren had posted that someone was busted for mixing up product to make some $$ but got busted. Bad enough to not get what you purched but mixed up junk in plain mean!

Does a 30# tank weigh 35# full or 30#?

The Net weight should be 30#
The Tare weight approx 5 #
The Gross weight would be Approx 35#

Yeah, 35 or 36lbs. for a new tank.
If the seal was broke ,they charged up a car. Isn't 5lbs. about a full charges for most mid size cars ?

Not sure about the mid-size cars but my 1982 Chevy Silverado regular cab calls for 44 oz. R-12 which is 2 and 3/4 lbs. Sure wish I could get my hands on enough to put it back to R-12. I found one 12 oz. can of Dupont so far. Am needing three more. Had to pay 30 bucks for this one can though!!

No way! Even the dual air monster SUV Caddy Escalade w dual system uses just 4 lbs.

This is a year old thread already. Still a valid point - you are buying the contents and the container is the "tare" weight which can vary some as said,
