When I picked the box up from the porch, I knew that I'd be glad that I bought this tank. I've owned steel air tanks in the past, and while I did expect this one to be lighter than them, I was surprised just how much so. Another pleasant surprise was the additional stabilizer on the bottom of the tank. Rather than having only one, as shown in the first five photos, there were two, as shown in the sixth photo of the tank near a compressor. I did quick leak test--admittedly for only a few hours--but the pressure was still there with no loss. Also, I like the form factor: longer and smaller in diameter than typical tanks of similar capacity. This is my second purchase of a California Air Tools product, and it probably won't be my last.

Not inexpensive but as long as you don't run over it, it will almost certainly last you your lifetime. If you are a buy-it-once person, do it - you won't regret it. If you aren't, buy a steel one for about half the price and it will probably rust out from the inside in about 10 years like mine did.Upon receiving, I loaded it up with 125PSI, closed the valve, and left it in the garage for a week - no air leaked out. Then I opened the valve and left my own personal hose (I prefer a long one) and fitting on it - still no leaks. So, the quality from the factory is very good. Welds looked nice and the paint job was good quality.Also, it has a water drain. Very few of these portable tanks have proper drains in the bottom.

This tank is a great alternative to steel air tanks. The quick connect coupler makes it easy to fill, and the valve holds air well over time. This tank replaced an old steel one that was rusted and heavy and leaked. Big improvement.

I had a spare air-tank that I used with my compressor, but it was steel. It was surprisingly heavy and difficlut to move around. THis California Air Tools aluminum tank is a fraction of the weight. It works perfectly, holds air, and ie EASY to move around. I highly recommend this if you do much moving around with the tank.

I like this tank but the hose that they sent with it leaks air when hooked up so there is something to bedesired there. Either the male attachment is slightly under-sized for the female connector on the talk orthe female connection is faulty? I don't know which but I will will determine this and replace which ever isat fault. Other than this it is a great tank.

Je l'ai acheté comme réservoir auxiliaire pour utiliser avec une compresseur 5 gallons et ça fonctionne très bien, j'ai donc un compresseur portable et du volume d'air si j'ai besoin en plus d'une tank portable en cas de besoin. Parfait pour de petit atelier.

Pros: light (purchased the AL tank), nice design, nice features (1/4 turn drain, valve to isolate tank from brass, can be filled two ways)Cons: cheap brass, poor assemblyPurchased this tank to match the California Air Tool compressor I purchased at the orange hardware store. I give in 3.5 stars because I really like the tank now that it works correctly.If you purchase this tank please be aware that your will need replace all most all the brass on that comes on the tank. It is cheap and clearly the part of the product that was skimped on the reduce costs. Had to replace all the brass in the in photo with higher quality products from the orange hardware store. The isolation valve and hose coupler leaked and the tee fitting split when replacing the leaky parts. Save yourself some time and have all of these on hand. All are 1/4” npt by the way.The tire chuck hose whip came with nipple finger tight only. Additionally it had an excessive amount of Teflon tape on the hose fitting end including tape covering the opening of the fitting. I also found this on the brass on the tank. This is very poor assembly quality that can damage your tools as the Teflon tape does not break down and clogs screens and jams tools. Sad to see California Air Tools put a sticker on the tank that proudly says it was assembled in the USA but has such poor assembly quality. Please leave the sticker off in future.

Hi AllI bought it a few days ago and the connection were air-tight (there was white Teflon installed, so perfect) and it does not appears to leak at all. The tank was much smaller than I thought (it appears bigger on the picture).

Very poor quality control. Looked and sounded like a good product. Very very disappointed! Right out of the box---four leaks at the top and one at the bottom. I had no intention of trying to tighten fittings because if they stripped, i just bought it (and I shouldn't have to tighten them---as i said---poor quality control). I was going to buy their 10 gallon compressor if i was happy with the tank but they can forget that if they can't even get the fittings on a tank on right.

I found the whole assembly well-thought-out for the casual user. The valve does a good job of keeping the air in when you want it to, the connections make it easy to either fill the tank or use it. Could they be tougher or better protected? Sure. But in casual use, this thing should last for a very long time. Key thing to longevity is to detach all hoses and other stuff while transporting it. You can't expect the tank valve to survive much abuse given how its installed vs. how the rest of the assembly acts on it.Welds on mine looked fine, just as the paint job. It's very light, and it stores a much more air than my compressor. Makes it ideal for quick refills of tires and like stuff, rather than having to lug a compressor and power cord around. I would also recommend it for large but intermittent loads, where your compressor can use it like a battery to store air that is going to be released in short bursts that exceed the capacity of the built-in accumulator.Using this tank in a fixed installation is likely a waste as similar steel-based tanks cost less. Downside of steel tanks, however, is that you have to watch for water (and the resultant corrosion).
