jonnythan:I'm not sure exactly what you're asking... if you have a drysuit, obviously you need to have an LP hose for it attached to your reg so that you can inflate it.
If your suit is new and did not come with an LP hose, go back to where you bought it and make sure they hand you one.
If you're asking about attaching the LP hose to your regulator, it's no big deal. Just find an empty LP port on the reg, screw it in hand tight, and give it a nice snugging-up with a wrench. Don't make it very tight, just good and snug.
jonnythan:Just FYI, you don't need to lubricate the O-ring at the regulator end of the hose.
It's not necessary for a static O-ring. Lubrication can attract some dirt and grime as well as mess with the torquing of the connector. It's not necessary so just don't bother.tau:Jonnythan,
One more question, why shouldn't I lub the O ring?
