So my A9 came loose again. 2nd time now. Could tell from the slight wobble when closing the JC to fill.
And a tiny weep from JC airholes when operating.
Thinking I might put a dab of locktight down there on it.
I don't need anything but the 501 connection, and I guess that's the only reason to loosen A9, change the connector.
Also, my oring #16. I haven't really had problems with it .. yet.
I did forget to 'lube' the oring after a cleaning. Just that miss caused a tiny leak into section A.
Re-cleaned and lubed, fine again.
However, it does seem to be slightly undersized as an original size standpoint.
Just looking at it, it barely seals - it is almost flush with the outer body.
I don't have spares *gasp*. From what I gather the replacement is: 15mm*12mm*1.5mm (or is it 11mm*1.5mm ?)
Also wonder if 1.6mm width might actually be best?
eta: that's Loctite. And the blue is 'removable' with a bit of force, the red - not so much (lots of force)
Gonna put some blue on once it warms up from being in the shed ha!
