Do you pack your SPG spool?

[fjpatrum]

So I finally got a new HP hose for the reg set I'm giving to my brother and I'll be testing it out tomorrow in the local quarry. I was wondering if you folks pack grease around the SPG spool when installing the hose. I haven't found anything yet in the manual as to whether I should or shouldn't but I haven't looked carefully yet either.

Suggestions?

I always grease dynamic seals and renew about yearly. I usually lightly grease static seals, except cylinder neck valves, but leave them alone until there is a reason to open it up.

Agreed. and I carry a second spool now. You can get them here but notice that there are 3 different sizes:
HP Spools "Stems"

Yeah, I actually took the spool I had in to get a spare. I unfortunately didn't get a spare for my SPG, just the one I'm giving to my brother. Thanks for the info on the grease, though. Now I'll be able to get the second SPG put on my reg for testing tomorrow.

I suggest you lightly grease with Christo Lube ($$$) or or one of the other cheaper oxygen compatible lubricants.

I always grease the spool too. You will notice when it is due again, because it won't swivel as easily.

I agree with Low vis not to "pack" with grease. I do put a little more than I would say for the o ring on a dive light though. lowvis is right about considering O2 compatible lube if diving nitrox. I use it. You can get it here:

about halfway down the list $3.50.

I don't "pack" it but I do lube the spool and the threads quite heavily. SW get in there and it take a fairly long soak to dilute, especially if the rig is being soaked under pressure.

I'm also "generous" with grease in this area.

Yep, a good coating. And when it doesn't move as freely: re-lube.
