Powertube tip

Came loose on me yesterday. Boy that causes a massive leak unless the trigger is pulled. It vibrated completely off. My question. Is how tight should it be and what's the preferred tool for snuggling it in?

level 7 most of us use a nickel. check and see if the o ring is still there or maybe needs replaced. I have never had one come loose and I usually tighten them pretty tight. level 10 would be a wrench, same tightness.

Like a nickel in your fingers. Don't use the full wrench handle. Some people have used a wrench to break the top of the power tube tip off.

I had one come off, once, a lvl 10. I guess I had put it on with just my oily fingers.

I will say that replacing the o ring on the tip has been the hardest of all I have replaced

Just happened to me last weekend too! Had a couple weird feeling shots that seemed "over pressure".....and then a pop and a big leak unless the trigger was held. Didn't want to mess with it at the field and realized when I got home what had happened.

So after the tip coming off, I cranked her in really tight. That seemed to cause bolt stick. I'd didn't fully reset a few times. So today I just made it hand tight. Didn't get through the first game before It started coming loose. Anyone object to me putting a drop of blue locktight on the threads? It shouldn't effect anything right?

Nope, you should be good.

But...are you sure you put the right o-ring on the tip? The only reason for that o-ring is to help the tip tighten down snug to the tube. It's almost like a lock-washer. But if you put an o-ring on there that's too small, it won't provide the friction needed to keep the tip tight.

And for what it's worth, I use a wrench myself to tighten down the tip. I just use a short wrench and tighten loosely until it stops. Then it's good.

I don't object at all, as I do not plan on disassembling your bolt.

It should only affect your ability to disassemble your gun. Its a component that is meant to be take apart for adjustment. not sure why you would need to make disassembly difficult. There is also green and purple loctite that is less aggressive. Check the threads to make sure they are clean/dry and that may help give a more secure hold.

As long as you use blue loctite, it shouldn't be a problem. Blue isn't hard to break, so it really won't make it more difficult to disassemble when necessary.

From the guy who posted angry comments about red loctite on Facebook last week.
