Rebuild a Conshelf XIV

[rsingler]

Interesting side development -
Went to ScubaGaskets last night to purchase, and their Aqualung HP seats and most of their AL kits are out of stock.
Is it folks compensating for not having Conshelf kits? Or is something else going on?

While we're on the topic, Is A145-75mm the correct Trident part number for the diaphragm?

That diaphragm may fit,

but I would be concerned about the width of the sealing flange (green arrow). It's pretty narrow in the Trident diaphragm.

OK, ladies and gentlemen, it looks like I’m going to have to find a replacement push on type Exhaust T for a 1085 second. It looks like Double Hose is gone and I had no joy @ ScubaGaskets. Does anybody have any suggestions for a confused amphibian?

Thanks Rob do you know which exhaust valve from Trident is used?

Trident does not have a suitable valve.
The mushroom required is 30mm diam

with a 2.5mm stem and a barb 1mm from the valve.

I have not found a replacement yet.
A knockoff cannot be larger than 30.8mm or it won't fit in later cases.

Having never had them apart side by side, are the Kirby Morgan Superflow 350 diaphragm and exhaust valves potential contenders?

Not the original type but it will fit on an old Conshelf XIV.

And as a suggestion: Never try to remove an old Conshelf XIV exhaust cover. The old rubber gets really hard and stiff with age and frequently cracks if you try to remove it. And if you do get it off without cracking it, it's almost impossible to get back on.

Is there no wiggle room below 30mm?...I would measure, but it would mean I have to go dig out my Conshelf 2nd stage.

Does the 29mm exhaust valve from Trident have too thin of a stem?

Here is a source in Chile whose website indicates they have the exhaust valve "in-stock":

Playing around with quantity in the cart, it seems they only have 4 left in stock....when I put 5 it tells me the "quantity is not available", but the site accepts a quantity of 4.
