I don't think it is needed. If you bump the valve, check it.

That type of valve is typically used with rebreather bottles. I have no problem working them on my unit. I also have Lola valves with a manifold whip on doubled lp50s/7, no issues working those either.

Ya. When I’m doing valve shutdowns on my doubles I need the feel of a large knob through my cold water gloves. I have no idea how easy or hard it would be to manipulate these valves when they are now half their size.

But....why?

But....why?

You mean why do short knobs exist? Or why should one have them? Or why should using one be different from the bigger knob?

what are your answers to each of the above? Though the first is not really important, so look at the second two questions you posited.

Because sinbad is bored and decided to started worrying about a manifold that doesnt even exist?

Pretty soon there will be a raging debate about whether sherwood, DGX, or thermo knobs are easier to turn compared to rebreather knobs

But I just posted a link proving its existence and saw one on a pair of doubles. What makes you think it does not exist?

You posted a link to some specialized rebreather valves not a manifold. But I will give you some credit, you haven't turned this thread into an advertisement for UTD yet so that's an improvement.
