Small wing for small cylinders, where to buy?

[halocline]

30lbs Tauchen Schnorcheln BCD Auftrieb Donut Flügel Einzeltank BCD Auftriebskompensator Tech Zylinder Freitauchen Sicherheitsausrüstung - AliExpress 18 Happy divers wing looks good but 30 lbs seems to be quite large.

Tauch-Auftriebskompensator, BCD-Donut, 23 Pfund Flügel, nur für Rückmontage, leichte Auftriebsausrüstung, Aufblasgerät - AliExpress 18 23 lbs might be better.

But I do want a "pull valve" (how do you call it in english?). I pull the whole inflator, the shoulder valve blows off. I have a Dive Rite inflator including corrugated hose and "pull valve" laying around here. I could attach it but I am afraid threads are not the same. Any experiences about that?

Why do you want a pull valve? They are a bad idea IMO, and totally unnecessary. It’s a common failure point in BCs. You can vent through the dump valve and the inflator.

If oxycheq is still making the 18 lb wing, those are pretty good. I’ve had one for about 20 years.

I ve been using dump valves for 40 years, they are great. I will keep on using them. They are no faillure point at all. But this discussion leads to nowhere.

Can you please measure the outside diamter of your China thread on wing? This would be very helpfull. Thank you!!!

No!

You asked for advice, you received advice, you paid nothing for it. Enjoy life!

I got you @Agro
The blue one is a cheap chinese "30 lb" scuba donut I got on amazon for less than $200
The black one is a classic dive rite 60lbs wing
The dive rite and elbow inflators are interchageable.
The china donut inflator flange fits the generic BCD tool

Self Diver, thank you very much!!! I will measure my friend's China wing and my Dive Rite pull dump valve, they are very different.

Do I read it right, diameter is 1 48/64 inch? I am not confident with inch, I use metric system.

The conclusion is that my dive rite and China donut inflator are interchangeable.
So...you need to grow a pair, buy a cheap Chinese donut and worse case, you learn to dive without the pull valve.
