What are you trying to say there?

Hey Frankart just seen youre a machinist guess you live by specs huh

AGD's torque spec is 35ft-lbs for the Flatline regs. They have a torque wrench setup with a cloth strap wrench to install/remove the bottles.

Ok maybe 70 is over kill but its still tourqued to spec not hand tight

[Muzikman]

I agree regs should not be hand tight! This can be EXTREMELY dangerous. I have come to the conclusion that the majority of the people using HPA system do not understand the dangers involved with that high of pressure.

ok, so what should i do........

right now my bottle is hand screwed onto the reg as tight as i can get it, and i'm gonna unscrew my tank using the reg from now on

[Muzikman]

Take it to an airsmith and tell them to put the reg on the bottle. This does not mean just any local Paintball shop, but a true airsmith. You could even take it to a dive shop.

Id go and get it torqed if I was you But Im not you

I'd just get it as tight as I could with my hands and leave it alone, because obviously none of you people realize how tight 3000 psi will make the threads.

Obviously you dont understand safty or specs. What about when the bottle is empty? Try and get good grades. Youre not old enough for a beer

I agree to Muzikman

[Muzikman]

The problem is that if the valve is lose and you go to fill it the threads will slam together and possibly cause a failure. Again, HPA is not as safe as people think. The people that suggest that a lose reg is safe because of the amunt of pressure that it will be under has never seen a tank go through a block wall. In HS shop class I saw a 280cu ft O2 tank that had about 2000psi go through a block wall and into the autobody shop in a split second and the wall didn't even appear to slow it down. If finlly came to rest on the frame straighting machine.

I'm ok with hand tight. Regs all have a vent on the threads designed to dump tank pressure if the tank unscrews. If the tank is unscrewed more than 1/8" it will blow the o-ring and vent in a fairly safe manner. Muzikman, you witnessed this at shatnerball last year. My 114ci maxflow vented that way.

As for screw in regs.... Those have always concerned me. I'm not worried about the tank coming off, if the tank unscrews you can look at the last paragraph to see what will happen. I'm worried about the REG unscrewing from itself. Early PMI regs did not have the locknuts you see on the new PE regs. I have a reg in my posession that unscrewed at an inopritune time. NOT a fun situation.

Though I avoid screw in tanks... in general. I have a mistrust of them.

I agree, most people in paintball have no respect for high pressure air tanks. Muzimans example is a beautiful way to show how powerfull compressed air can be. But something like that will only happen if you CRACK OFF the reg. (note that if you crack off the reg of a flatline, there's a pin that will prevent the tank from violently venting. AGD rocks :-) ) Overtightening a valve WILL cause stress fractures, and weaken the reg's mounting threads. (This IS what happened with the valve on my 114ci maxflow) Making something like muzikman's example much more likely...... Same thing about overusing loctite. that can break that mount, esepcially if a reg is reinstalled after it is removed.

[BlackVCG]

Hand-tight is also a very subjective term.

With my Flatline removal tool, I can push the reg into the socket with it attached to a torque wrench set at 35 ft-lbs and I can get it to click, meaning it is at 35 ft-lbs just by putting both of my hands on the bottle and twisting.

Pains me to say it but why do you think Smart Parts sell the lefty threaded valve.

Let alone a tank full of air?

You do know that they make maxflows where you can put any type of screw in tank on...right?
