Ninja UL2 Air Tank Regulator 4500psi
Ninja UL2 Air Tank Regulator is Ninja's lightest regulator to date, built off everything that made the Pro V3 a mainstay on the field and then trimmed down even further. It's machined from 6061-T6 aircraft grade aluminum, weighs in at just 123 grams, that's 31 grams lighter than the Pro V3, and threads onto any tank with standard bottle threads, not just Ninja's own. If you're running a 4500 psi HPA tank and want tournament-level performance without the extra weight, this is the regulator to look at.
Made in the USA. Every UL2 is designed, patented, and manufactured entirely in-house, with direct factory support if you ever need it.
Ninja UL2 Air Tank Regulator: Lighter By Design
The weight savings come from a smarter build, not fewer features. Ninja swapped the rotating bonnet for a fixed one, which cuts out extra moving parts and drops weight without touching performance. You still get the dual o-ring bonnet seal Ninja is known for, so the ASA connection stays airtight and the o-rings last longer between services. It comes in five colors, Black, Red/Black, Blue/Black, Grey/Black, and Purple/Black, so it's easy to match your tank or your setup.
Fits Way More Than Just Ninja Tanks
It fits Ninja, Empire, Immortal Air, HK Army, JT, and honestly any tank with standard bottle threads. If your current tank uses the same threading, you can swap this regulator in without buying a new tank to go with it.
Dial In Your Output Pressure
Out of the box, the UL2 is calibrated to work well with most modern electronic markers at 550psi output pressure, so most players can install it and go. If your marker likes a bit more push, the included shims let you raise output up to 750 psi. Running something that prefers lower pressure? Pull the shims out and you can bring it down to 450 psi. Either way, you're not locked into one setting.
Burst Discs and O-Rings Are Built In
Safety isn't an afterthought here. The UL2 has both high and low pressure burst discs, so it's protected if pressure ever climbs too high or is over filled. Combined with the dual o-rings at the top, you get a regulator built perform safely and reliably.
What's In the Box
Every UL2 ships with the regulator itself, Ninja O-Ring Fill Valve and full color Micro Gauge already installed, plus the shims for adjusting pressure, a full maintenance kit, and an instruction manual. You also get access to Ninja's USA-based factory support if you ever need it.
One thing worth knowing upfront: Ninja doesn't allow third-party or aftermarket parts inside this regulator. Installing them voids the factory warranty, and Ninja won't service a regulator with non-Ninja components installed. If you're ever unsure whether a part is compatible, reach out to us before you install anything.

Arrived with no issues and was easy to assemble. Would recommend Discount paintball
Really glad I bought this. SOO much lighter than my ancient old tank, and also smaller/lighter than my more recent standard HK 68/45. Definitely worth the buy.
Thanks discount paintball.
Great Reg got it set to 400psi for my emek and its soft and 280fps get that wear and tear down on the internals.
Threw in the shims and my a5 is powered up!
Super light ! Great color options.
Bought this to replace my empire flow regulator, (not purchased at discount paintball)because for some reason the empire reg would have a slight side to side play when I threaded it into multiple different markers. Switched to this regulator and couldnt be happier with the purchase. Ninja products never disappoint
These are very light tanks. I got the 68 ci and it is small and super light weight. The back is slippery so I added a tank grip. I used it all day this past weekend with no issues.
