MK17/G250V hose connectors

[vixtor]

Hello,

Now that the Miflex HP hose is available, I intend to switch all my hoses to Miflex. I see that for the regulator, two versions are available:
- 3/8" M UNF x 9/16" F
or
- 1/2" M UNF x 9/16" F

Which one is the right one for MK17/G250V?

I beleive that the 3/8" UNF is the one you need.

Remove both the primary hose and octo hose from your first stage. If the male threads are the same size then you need the 3/8" hose. If the primary thread is bigger, than you need the 1/2" hose. I've only rebuilt a couple of Mk 17s but I don't remember any Scubapro first stages having a 1/2" primary hose.

Hope this helps some.
