Mariel USA Disposable Tank of Nitrogen (Filled)

I was happy to receive these tanks (2) to test my new MiniSpit. I had pulled a sub 250 micron vacuum that held for days with little loss while I waited for nitrogen. So I was surprised to find a slight leak while under pressure. Was able to put over two hundred pounds pressure on system using both tanks. Have to admit they were worth the wait.

Considerably smaller than I expected for a disposable container :-(. If your buying this to terminate your pain and suffering then you'll want to order 2 if not 3 cause 1 didn't work for me! Going to try the Largest container of Helium next! If I don't leave a review there then you'll know it worked.....

Bought this to install a mini unit over fourth of July weekend. Got everything installed and ready to purge. Connected this can and it was empty. So frustrating. Had to scramble to scrounge up other purge option last minute since all the stores were closed for the holiday.

This worked fine with C&D 1/4" Thumbscrew Core Depressor (Part No. CD5050). Was able to pressure test Chrysler Town And Country front and rear AC from vacuum to about 75 PSI with one disposable tank. Was expecting a little more pressure out of it but at the end the test revealed no pressure drop and system has been working fine without loosing pressure for over a month now. If I had to do more work with nitrogen I would consider getting a 22 cu ft cylinder to get more pressure and volume out of it. For small one time pressure test/purging/drying these seem to be OK. The tank seems to have a refill valve too.

Didn't seem to have any nitrogen in the tank!

Excellent product. I used less than 3/4 of a tank testing a single zone mini split at 10 feet of distance.

Was enough to charge my 1.5 ton mini split with 15' lineset to 140psi. A little low for pressure testing but it worked.

Good product, Should be enough to blow out and dry some new lines. I might need more but will see.
