Reg Installation Question

[Warren_L]

Hello folks, still learning all about equipment...

Just an update (if anyone is interested) .... I was inquiring around about which reg to buy over the last couple of weeks. Considered the Genesis GS200, Tusa RS-230, Mares Abyss, Apeks ATX50/ATX40, and Scuba Pro MK25/S600.

Just picked up my brand new SP MK25/S600 with R-380 Octo this morning.

Anyhow, I was wondering how tight the connectors need to be to the LP ports on the first stage? And when I connect the BCD inflator hose to the LP port, similarly, how tight do I need to tighten? Probably a silly question, but I've never done this before.

Remember it is the o ring that makes the seal not how tight the connection is.Tighten the connection snug enough so it wont come loose on its own.It doesnt need to be cranked down as tight as you can get it.If you are not comfortable doing this have a dive shop or an experienced diver help you out.

Thanks for the info. I actually had everything put together at the LDS where I bought it and realized once I got home that I would have to eventually disconnect the hoses. Probably useful to know how to put them back on properly.

Just out of curiosity.

Why will you eventually need to disconnect the hoses? Unless you are going to service your own gear which I don't recommend since you're unfamiliar with the hose tightness.

Good advice. (Most) regulator first stage bodies are made of brass, and brass is a very soft metal. You can easily damage a port thread by overtightening the hose. Just snug it up.

Changing hose lengths is a good reason for someone to be disconnecting a hose.

It's actually more for my dive computer and SPG, which I have yet to attach. I want to add a quick disconnect to it, which I'm assuming uses a different hose altogether.

Being an aircraft mechanic we always use one rule of thumb, tighten it until it strips then back off a quarter of a turn
Not Really, I think lal7176 said it right the oring is the part that does the sealing as for the tightness on the threads just snug enough that it won't come loose with normal use.

All of the quick disconnects that I'm familar with use the same hp hose. Your LDS should be happy to install it for free when you buy it.

What if you dive dry sometimes and wet others. Not everyone wants to have that whip dragging along when they are not using it. How about an oring or hose failure. Don't want to cancel an entire dive trip because somebody told him only a dive shop could change his hose.

I figure in the end you're always better off knowing how something is done, even though you may not need to do it yourself. I just bought a used dive computer which I've installed myself. Now I know!
