4500psi High Pressure Composite Cylinder Aluminum Liner Carbon Fiber Fully Wrapped PCP Paintball Air Tank (Empty Bottle)

Bumped up tank capacity on my Air Venturi Avenger from 180cc to whatever capacity this tank actually is. I could swear I bought the 500cc but this review listing says 420cc. Either way, the bottle performs great and threaded right onto my adapter. Slap on a 3D printed barrel band and you're good to go!

Got this for my raw hm1000x air rifle. Will not work with the old style barrel and silencer as the bottle is two long. But if you have a barrel with no sleeve ad silencer it works out great. No leaks and best price for a 500cc carbon tank any where

BACKGROUND: Ordered two Sanoolir .5L 4500psi air cylinders thru Amazon in March 2022 at a cost of $149 each. Cylinders arrived in about a week and were well packaged with bubble wrap, plastic thread protectors inserted and easy to read spec sheets. - - - SPECS: the .5L cylinder dimensions: Total Length of 305mm and 60.3mm diameter. The cylinder tank neck is 11mm in depth with a diameter of 31.5mm. With HP valve installed the empty air cylinder weighed in a 22.4ozs. According to the label T700 is the carbon fiber used and the service pressure rating is 30MPa or 4,351psi or 300BAR. Cosmetically, the cylinders I received were clean, glossy and the specifications label with a black background and silver ink is easy to read but does not distract from the appearance. - - - INFO: The cylinders I received were manufactured in China by Wuhu Hexger Technology in November 2020. While my cylinders both had diameters of 60.3mm, the manufacturers reference diameter is 61mm. - - - THE BAD - - -: I had two HPA valves with true M18mm x 1.5mm threading. After inspecting the cylinders I attempted to install one of the HPA valves into the Sanoolir cylinders and encountered strong thread resistance with approximately 25% valve thread remaining. Attempted install with the other HPA and same results. Both valves properly installed into the second Sanoolir air cylinder. Was going to return the improperly threaded cylinder to Amazon and purchase another however the .5L models were no longer available. I ordered the Kmian Tools 18mm X 1.5mm HSS Taper and Plug Tap set ($18 delivered) and repaired the defective threading. The Kmian Taper and Plug tap set is performed greatly and while I’m not sure how often I’ll use it, it’s well made and a good value. - - - SUMMARY: based on my experience I’m rating this product 3 stars.

ordered jut a bottle. threads very loose. i believe it was used.

I use this as a "Buddy Bottle" for my PCP air rifle. (Benjamin P-rod) Works great! Looks great! Would definitely recommend this bottle to my friends.

Exactly as described, great tank and a great price

I order two of these a couple weeks apart the first one had a date 2022 was good, the next one had a date of 2021 and the glass finish had bubbles in it.
