Ninja 90ci 4500psi Carbon Fiber Air Tank & Fill Station for PCP Air Guns

Well I pick this up because I have to Benjamin Marauder air guns that I fill with the carbon fiber tank and all I can say it holds the pressure at the dive shop I go to they fill it to 5000 PSI and it does not leak I am a truck driver so I am gone a month at a time and I come home and it's always right where I filled it I would highly recommend this product it works great it's little easy to transport around I have a Hills pump that I use as well but when I go on hunting trips the tank is easier for me to transport in my truck

Ninja 90ci tank filled to 4500 psi and held air as it should have. The PCP fill adaptor leaks through the pressure bleed port even with the bleed valve closed. I have been using using high pressure air tanks and pcp air rifles for years not to confuse this with a new user issue. This item is NOT ELIGIBLE FOR RETURN to Amazon so please beware!! We have sent the manufacturer information regarding the issue and will update review with any new information.UPDATE- after contacting Ninja with the issue they responded and corrected the issue in a timely manner. Kudos to Ninja rating updated to 4 stars.

Good product. Sure has made filling my PCP air rifle MUCH easier! I've even grown to appreciate the regulator, allowing me to fill my rifle w/o having to watch the pressure; it'll fill to 3Kpsi and I'm on my way.Another nice feature is that I don't have to add any other fittings to fill the tank, as it has a male foster fitting before the regulator, so I can connect the compressor directly to the tank & begin filling.The only downside is the short, stiff hose. I replaced mine with a 36" micro-bore hose and I'm happy. This, however, is NOT enough of a problem to subtract any stars.If you're looking for a method of refilling your airgun in the field, don't hesitate. Get it.

The bleed valve emptied too slow, lost 400lbs when disconnecting. Hose is not a microbore and would not fit on crosman fitting, fit on air venturi. Slams your rifle, as soon as you crack the valve. Bought a WTG with a slide check to replace it. Now my rifle fills slowly and loses almost no pressure on disconnect. So buy the other one. Much better. If i had it to do over I would just get a good used 60 min fireman's tank and fill set. The bottle is good but 90ci is not very big. Not all that many refills on a 230cc rifle tank.

Bottle looks nice valve was not tight was losing pressure slow leak !! Tighten that up seems to be holding pressure now waiting for one more piece to try on my hatsan Gladia’s

Poor construction and quality......fill valve leaks as soon as disconnected from fill station. Searched the internet and seems to be a common problem. Filled to 500 psi to test....I am afraid to fill to the recommended 4500 psi as the leak will surely increase.....DO NOT BUY....processing amazon return......UPDATE 01/27/16After connecting and disconnecting the regulator and trying filling several times, the fill valve leakage stopped and the tank is holding the air pressure. I believe the valves needed proper seating. Upgraded review from 1 star to 3 stars and do not know if the problem will reappear in the future. However, for this price the tank should perform properly right from the first time.

Not sure why but will not charge my PCP rifle past 250 even when the tank is full at 4500psi gun is 300bar... other than that tank is very nice and the fill station works great!!

bought as a gift for my husband - he was thrilled with it. He did have an issue something with the valve but he got it fixed and is good to go.
