Review: California Air Tools Delivers! - High quality air tank. Best fit for the back seat of a pickup or the cargo area of a compact. I swapped out the quick-fill coupling on the shutoff valve side of the coupling tee for a 5-In-1 universal coupling just for versatility, but everything else about this tank fits my specs. Accurate gauge, professionally manufactured with high-quality materials. Factory finish is first-class and drain valve is in the right place.
Review: Well Made - Very nice portable air tank. Light and easy to use for an old guy like myself. Definitely worth the money. Definitely recommend.

### ⭐⭐⭐⭐ 3.5 stars - Nice tank, cheap brass, poor assembly
*by D***M on February 4, 2019*

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 assembly Purchased 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.
