Review: Surprisingly Light and High Quality - 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. Review: Great tank, excellent value - So far, this is a fantastic tank. Being made out of aluminum it’s dramatically lighter and easier to casually throw around and bring from place to place. The shipping box it came in, was well packed, extra thick cardboard with straps and plenty of foam reinforcements. I’ve seen some complaints about the quality of the brass fittings. They do look kind of thin walled. I’ve been trying hard to not bump them very hard since that three-way contraption sticks out quite a bit. Even if I do end up, breaking the weakest looking tee fitting off, it’s just standard 1/4”fittings, everything except the on/off, Schrader, pressure, relief, gauge all in one manifold and it actually looks pretty well made. ## Features - 5 Gallon (Rust free) Aluminum Air Tank - 1/4" Universal Quick Connector - Air Hose with Tire Chuck - Lightweight for easy transporting - Maximum PSI 125 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G75OUTI | | Additional Features | Portable | | Brand | California Air Tools | | Brand Name | California Air Tools | | Capacity | 5 Gallons | | Colour | Silver | | Compatible Hose Diameter | 0.25 Inches | | Customer Reviews | 4.3 out of 5 stars 233 Reviews | | Global Trade Identification Number | 00743369705109 | | Hose Length | 48 Inches | | Included Components | Air Tank & Air Hose | | Item Type Name | Auxiliary tank | | Item Weight | 10 Pounds | | Manufacturer | California Air Tools | | Manufacturer Part Number | CAT-AUX05A | | Material Type | Aluminium | | Maximum Pressure | 125 Pound per Square Inch | | Model Name | CAT-AUX05A | | Model Number | CAT-AUX05A | | Power Source | Corded Electric | | Recommended Uses For Product | Power Pneumatic Tools, Tire Inflation | | Special Feature | Portable | | Style | Aluminum Tank | | Tank Volume | 5 Gallons | | UPC | 743369705109 | ## Product Details - **Brand:** California Air Tools - **Capacity:** 5 Gallons - **Colour:** Silver - **Included Components:** Air Tank & Air Hose - **Item Weight:** 10 Pounds - **Material:** Aluminium - **Power Source:** Corded Electric - **Recommended Uses For Product:** Power Pneumatic Tools, Tire Inflation - **Special Feature:** Portable - **Voltage:** 12 Volts ## Images ![California Air Tools CAT-AUX05A Lightweight Portable Aluminum Air Tank, 5 Gallon, Silver - Image 1](https://m.media-amazon.com/images/I/7112TNNzucL.jpg) ![California Air Tools CAT-AUX05A Lightweight Portable Aluminum Air Tank, 5 Gallon, Silver - Image 2](https://m.media-amazon.com/images/I/7185FPik1eL.jpg) ![California Air Tools CAT-AUX05A Lightweight Portable Aluminum Air Tank, 5 Gallon, Silver - Image 3](https://m.media-amazon.com/images/I/71YSlcxWA+L.jpg) ![California Air Tools CAT-AUX05A Lightweight Portable Aluminum Air Tank, 5 Gallon, Silver - Image 4](https://m.media-amazon.com/images/I/71IrlCp46rL.jpg) ![California Air Tools CAT-AUX05A Lightweight Portable Aluminum Air Tank, 5 Gallon, Silver - Image 5](https://m.media-amazon.com/images/I/71VPq9n4MlL.jpg) ## Questions & Answers **Q: What is max pressure? 100psi? 150psi?** A: 125 is red line on gauge, and the blow-off is 140 PSI.
