VCA randow flow generators

[JohnMzreef]

Does anyone else have trouble getting these to stay attached to the end of their loc-line? Seems the fit is very loose and I keep finding mine in the bottom of the tank. I have had them for a few years actually and it has always been a minor problem that would diminish as biofilm would accumulate. Now I find myself wanting to dial up my return pump a notch and they just can't handle the increased flow.
Does anyone know a workaround? Teflon tape?
(I complained to BRS and was told they are "wearing out" - seems ridiculous for a plastic item with no moving parts. They should snap on tightly and last as long as any loc-line component.)

@JohnMzreef I just put on them on my returns and noticed they went on much more easily than loc-line would. I don’t know if it’s tolerances or the material. Sorry I can’t be of help but thank you for the heads up about them possibly falling off. @Bulk Reef Supply explanation seems pretty silly. The parts don’t move so how can the joints on the pieces wear out.
