Genesis 7/8 UNF valve plug

[NJDiver07866]

Have a set of 3500 PSI steel 100 with the older style 7/8 UNF neck (smaller size)

They are currently set up as doubles with right/left hand valves. I'm breaking them down into singles and need some help.

I found the right hand thread plug pretty easily... (with wheel on left.. just like a standard valve setup)
This is what it looks like..

Genesis Right Hand Plug

I'm having trouble finding the left thread plug. LDS is kinda unsure... I 'borrowed' a plug and took it home today and it looks like it is not long enough..
It looks like this..

Is this the correct plug? or is this too short and the wrong one? It looks like it does not go deep enough. I can feel the one o-ring engage the valve, but not the other..

Thanks for the help

I did the same thing to mine (7/8 thread Genesis valves) and the both plugs look like the top pic, my LDS did it for me so I don't know where he got the plugs.

The second plug is from a Generic valve manufactured by various Italian manufacturers for their own lines. Some "brands" do buy this generic line and just "badge" it, but, its not the same manufacturer as the Genesis plug. That generic valve plug is manufactured by San-o-Sub in Italy (identifiable by the Green O-Rings).

Its probably best to get the correct part if you can, but if not, it could work, the thread is obviously the same, so measure the shaft length, diameter and the o-ring positioning, a fraction out on the o-ring positioning wont matter as long as they seal into the shaft. If both o-rings bed down and the plug screws down tight, it should be fine.

I have the 2 separate valves for the PST 3500 7/8's and I am looking to twin my tanks.

Thanks for the help everyone.... Yea.. the Generic one just is not long enough.. I measured it and only 1 o-ring is trapped in the barrel. It works... but..... I found another LDS that actually had the longer genesis plug so I snatched up 2 rights & 2 Lefts so I'm good.

Learned a ton about the 7/8 vs the 3/4 size also in my travels intresting stuff..along with a few other wonky sizes... 1/2 and M25

KCBAR4.. thanks for the offer.. but this just temporary.. I will revert back to the doubles in the future.
