0.5Gallon 304 Stainless Steel High Pressure Mini Small Portable Air Tank Air Reservoir Water Storage Tank (2L-SG)

The only downside of these tanks is how long it takes for them to arrive (about a month). The quality seems very, VERY good. They feel a little heavy for their size which reinforces the impression of durability. The welding of the end caps is excellent. The weld on the mounting bracket is adequate for static applications but I’m not sure how it will hold up on mobile applications if there is a lot of vibration – I’ll probably need to install some rubber shock mounts. All in all I’m happy with my purchase.
