how do i get my reg back on my tank?

[Brak]

subject says it all. i recently got my tank back from hydro (hydro number 420, haha) and they didnt put my reg back on. so does anyone know a good way to put my tank's reg back on (68/45 raptor)? like what kind of loctite, where to put the loctite, etc?

screw it on and tighten. Loc-tite is not neccessary, nor even recommended. there should be an o-ring at the base of the regulator threads (the part that screws into the tank...) that does the sealing.

if you feel unsafe without loc-tite, a small dab of BLUE loc-tite above the vent hole will be fine.
DO NOT USE RED. It can cause damage to the threads upon removal, which may cause it to fail the visual part of your next hydrotest.

thanks, the o ring looks ok, i just didnt know if that was enough to seal it. thanks

I definetly would not put it on WITHOUT Locktite.

That o-ring won't keep the tank from backing off the reg. and with very high pressure you have a deadly missile if the tank comes off. Air America reccomends the 545 locktite (blue) for holding regs on. I believe the 545 is rated to 10,000psi and is removeable with tools. The Red Locktite is permanent and requires a large amount of heat to remove. I have used the red on CO2 tanks when replacing pin valves with ON/OFFS and had to heat the tank later to get the valve off to put in an antisiphon and the red locktite didn't do anything to the threads on the tank. However, using heat might do something to the carbon fiber wrapping of an HPA tank.

Short answer USE 545 LOCKTITE!!!!!!!!

Only part you have to be careful on is your vice and wrench. Something with rubber grips on the vice and don't strip the nut with the wrench.

Find a Fire supply place that has all the tools, I bet they'll charge you like $5 for it.

You need the Loctite, it is the only thing keeping the REG from unscrewing itself from the tank. My Raptor came from AA with blue Loctite holding it. I personaly use Loctite 242 (also blue) on all my tanks and air fittings.
Last weekend at the PPl tourny in Vegas I talked to the guys from the Centerflag tank booth and they use/recomend the Green Loctite

wow. :)

green!? good lord, that stuffs like JB_Weld...

I much prefer using the proper amount of torque over using loc-tite (on HPA tanks that is, i use loc-tite on co2 tanks). If your torque it to like 25 ft/lbs, the tank wont unscrew, and you can avoid using loc-tite.


air america, AGD, and a few others use no loc-tite. at least, none of the tanks i got from them use it. A lot of manufacturers are stopping the use of loc-tite.


DO NOT USE RED (or green). if you use loc-tite at all, use blue 242.

battle group, that wont happen. not only do you have to unscrew it REALLY far, but there is a blow-off vent to prevent it.

I just used a little dab of blue on mine. Have you considered duct tape? It seems to work for Red Green.

Actually I just had Air america Replace my 68ci with an 88ci tank and the told me they use 545 loctite on the reg and recommend 545 loctite on the guages as well.

I have seen it on a CO2 tank where someone wasn't paying attention and unscrewed the tank from the valve and the bleed off scared the ....... out of everyone and they dropped their gun and put some huge scratches in it. With 4500 psi air you could easily get an air embolism from that high of a pressure bleeding out! Why take chances.....use the loctite and be sure you won't have problems.

An unexperienced player who has not used HPA and is not paying attention could easily unscrew the tank and hurt someone.

545?

thats not thread locker, its a sealant. I agree, good stuff, use it on stuff i do for other people (i just use pipe dope for my stuff...).

but i dont use loc-tite for HPA.

besides, this is a raptor, so its not going to get torqued alot like a screw in. So i stand as not reccomending thread locker. sealant is really unnecessary as well, since the threads arent tapered (so it wont really be able to hold much).

[battlegroup]

That's what Air America suggested I use for my guages. It's still medium strength thread locker but it's rated to 10,000psi

what is an air embolism

when a burst of high pressure air either breaks skin or drives everything that lives on your skin INTO your skin. You can get gangrene from it.


545 has no locking ability. it merely seals, and in doing so will make it slightly harder to turn the screw. The sealing effect is utterly useless in this case, as the o-ring is what takes the pressure anyway.

[battlegroup]

Dude, do whatever you want but there is no way I would even think about not using loctite.

and 545 is used to lock and seal fittings. Here is the link to the data sheet for 545 from the loctite website

http://www.loctite.com/datasheets/tds/Product_545.pdf

TYPICAL APPLICATIONS: Used to lock and seal Hydraulic and pneumatic fittings......

545 requires 8-24 ftlbs of torque to loosen
242 (blue, medium)requires 70-150
262 (red,permanent) requires 220-440



A burst of air at high pressure will cause an air embolism which is where a large volume of air enters the blood stream and causes a blockage in the lungs, a heart attack, or stroke, all of which can cause death, and is very painful. It can also travel to the kidney and cause kidney failure

[litestab]

how would the air get there?
