Review on CE Approved Gurlleu Carbon Fiber Air Tank - 30 Cu Ft/4500 PSI For PCP Paintball Compressed Air System With Regulator Valve And Dual Gauges Set (Empty Bottle) by Thomas Ramirez

The tank itself is nice, well made.The valve on the other hand is NOT. I filled my tank to 4500psi and tried to fill a pcp air rifle only to find I had a leak at the output gauge. Emptied the tank and removed the gauge to find what looked like a loctite type sealant on the threads, no o-ring. Fixed that leak and refilled the tank to 4500psi. Now the gauge was fine but the valve started leaking under the on/off knob. Emptied the tank again. Contacted the seller to ask what I needed to do with this Chinese turd they had sent me, and they sent a pack of four or five o-rings.I installed new o rings in the valve, filled the tank again.and still had a leak. Emptied the tank AGAIN. and proceeded to remove every single thing that is attached to the valve body and sealed all the threads with yellow gas line tape (similar to the Teflon tape).Now I currently have no leak. Knock on wood.Would I buy it again? No. Having to fill and empty three tanks full of 4500psi has soured me on this purchase.
