Couple of things I could use some advice on (apologies for the essay below :))
1. My Mag started leaking down the barrel, so I went to change the power-tube tip o-ring, only to find I had to some odd after-market powertube tip, with no slot in it, which I must have fitted years ago (and forgotten about).
It must have done it up really tight as there was no way it was coming off without getting damaged. As I still had the original AGD powertube tip, I wasn't too worried about damaging this one, so I got a pair of pliers on it and applied loads of force......and managed to unscrew the whole powertube from the end of the valve (this is a level 7 valve). Oops!
Managed to get the powertube tip off eventually, but wasn't sure about how best to re-fit the powertube (which has a red gasket and seemed to be fitted with some kind of loctite/sealant). I ended up just cleaning all the old dried gunk out of the threads, applying some blue loctite and screwing it back in - tightening with some cloth wrapped pliers - should that be ok, or do I need to use a stronger sealant?
2. I'm taking my 68cu in 3000 psi air tank in to be hydro tested. I've got an air america reg which screws directly into the bottle. I managed to removed the reg by clamping it in a vice and twisting the bottle by hand (took a fair bit of force, but wasn't really difficult). Once the bottle has been tested, how should I go about re-fitting the reg? Blue loctite and a fair bit of muscle power? Or should I use a different sealant and a specific amount of torque?
Any advice appreciated!
