Single screw on dump valve won’t…

I'm thinking it's the set scew and that valve wont' work well with the "Gable glands)

Think a ring around the part the cable goes into with a threaded hole. and a longer set screw in the hole.. As I Said I've seen that before. I just don't know what it is called and I'm not that good at drawing.

Google.. However.. Knows more than I do.

This is the design. Likely the wrong size but it's the design and it's less than 2 bucks

Shaft Collar

If the cable fits through the collar you linked, it WILL fit through a wire gland.

And yes, a company I worked for used those collars on industrial machinery as well as cable glands for the electrical that fed the equipment.

Those collars are typically used on solid hard shafts to prevent them from shifting or moving around. Work good for that application.

They don't work well with applications that involve a hollow item as in the case of the outer jacket sleeve. That is due to limitations of how far the single screw can go in, how much pressure the outer jacket can take in the small spot the screw presses on before deforming to the point that the inside cable is pinched. The valve involved using collars like the one you linked are badly designed and unless you come up with a better clamping arrangement that will always be a failure point.

I am not talking about "status quo" fix, I am talking about making a one time permanent fix so one doesn't have to keep revisiting the problem.

A clamping system that has nearly the entire surface evenly clamped will be much less failure prone in the future.
