That's it Tim, the whole shootin' match, one rubber seal:

problem is you have to be very carful when you bend the four
tabs up so as not to fatigue them anymore than you have to. You
will only get one chance because it's like bending the lid on a
tin can, flex them a few times and they snap off. If it's been
taken apart before then you stand about a 90% chance that the
tabs will break off.
Setting them can be a problem also. This is a plate I made up to
support the valve while I set the tabs with the staking die:

plug and took out the valve plunger. Maybe he can post a couple
of pictures of that dissasembly.
The valve is still usable even if the tube is broken off, it
just won't self adjust to the temperature.
