So I just got a new tank reg...

[nighthunter]

This is probably a dumb question, but I've always gotten my tanks preassembled and I just want to be 100% sure I'm not about to explode myself or create a DiY missile in the staging area.

I just got a new (ninja) reg for my HPA tank. Can I just thread the new reg into the tank by hand and it'll be fine when I fill it with air? Would I need a specialty tool to crank it tight or is hand pressure all I need?

Also the orings on the reg go in dry, correct?

With your post and the subject I have to.

In all seriousness, make sure it is tight, the oring and the threads work together to keep it from backing out or creating a missile. I have always used hand tight, nothing crazy like a strap wrench or vice.If you decide to put a little dow 33 on the oring it will not hurt it but it can go in dry.

Hand tight is just fine.

I usually snug it lightly with a strap wrench. Mark a line on bottle and reg for peace of mind. Paint pen works well.

I've always hand tightened without any problems. I'll give it some muscle, but I've never used loctite or strap wrench or anything

I'm constantly swapping regs on my tanks. Put a slight coating of grease on the O-ring. This will make life easier if you ever want to remove the reg again. Then just hand tightened. I've done this dozens of times without any issues.

I've always used a strap wrench and reg removal tool to get them on there tight but I also know the next time they are coming off is in 5 years for hydro. I don't think there's anything wrong with hand tight I would just crank down on it as much as you can

As long as the reg is screwed down enough so there's no (or minimal) gap between the bottle and the reg, you should be good.

The idea is to prevent that reg-to-tank oring from extruding out of that interface, which would cause a leak. And that's the worst case scenario: air gushing out around that oring. So it's a pretty safe either way.

The tank reg has a groove in the threads for safety if it was to unscrew under pressure it would make a lot of noise but it’s not going to take flight. Under pressure it would be very difficult to unscrew as well.

If you ever fly with your tank the regulator needs to come off so the inside can be inspected. Otherwise the airlines can take your tank.
