Is my HPA tank's integrity compromised?

I always use a Dye cover on my 68/4500 and rarely remove it. However, when I removed the Dye cover to use the tank with a coiled remote on a pod pack today, I noticed a large crack on the bottom of the tank. Some players at the field told me that I shouldn’t worry, that it looks like only the plastic coating is cracked, and not the actual fiber wrapping the bottle.

Still, I am concerned that the tank won’t pass hydro because of this. But worse yet, what has caused this crack to form on my tank? I purchased this brand new back in late January and have only noticed this today. Like I said, the Dye cover rarely gets removed, so I don’t know how long the crack has been there.

Is this only cosmetic? Can I put epoxy to fill the crack or should I send it in to Ninja? I wouldn't want to put my safety at risk with this.

I have heard from Ninja that a LOT of tanks have the black coating cracked and chipped. From what they told me, it is nothing to worry about as it is only the cosmetic covering. I have seen pictures of Ninja tanks completely spider-web over in cracks after expanding during a fill. You may want to speak to them though.

I have a chip on the coating near the valve. Ninja just told me to use epoxy to cover it if it really bothered me.

I recently sent NinjaPB a 68/4.5k PE tank for a reg swap. The tank had some loose chipping that covered the size of a 25 cent US coin. They returned it with the loose stuff off and added NO epoxy. Good for 5 more good years now.

THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

I sent Ray over at Ninja some pictures, we'll see what he says about it.

If it's cosmetic, I can live with it!

I don't know, will you have trouble at the field getting a fill with that sort of crack? My local fields won't fill a tank if it is anything less than perfect.
If at first you don't succeed set fire to something. It probably won't help but it will make your failure more festive. Almost a celebration.

Thankfully league members have self-serve fill stations, so I should be good.

My field gave me issues with some of my 9 HPa tanks... most of which aren't in hydro.

Now, I drive around with two scuba tanks! HAH!

But yeah man, that isn't something to worry about unless the fibre wrapping underneath is damaged.

I have a ninja 50/45 that I got in 09 and it is cracking like crazy... I was thinking about calling them up to find out what was up with it. I am not happy at all... I was wondering when I have to get it hydro'd will they still hydro it with all the cracks? I know that is not for a long time, but still would like to know....

Hmmm... I was going to get a 90ci Ninja. This thread just changed my mind.

If I were you guys with the cracked tanks I would send them back.
