Rotary Fitting leaking!! Suggestions needed.

[Fatfool]

Use Bitspower rotary compressions.

Such as this double rotary:



Or this triple rotary:



But in your tubing size.

I know, I know, you'd rather eat at McDonalds...

To be honest, other than the cost, I'm quite apprehensive as that sort of rotary actually has even more chance to leak.... (more rotary joints after all)

Full cover block - 100 USD
Rotary Fitting - 20 USD

Something's wrong here. Sure both aren't mass produced parts and both are targeted at enthusiasts but that kind of price comparison shows the absurdity of the price of a fitting. Full cover blocks obviously demand higher investment and time to design. Those C & C machines aren't cheap to rent either. But fittings manufacture?
Reason? Full cover blocks are produced in different and completing designs by ~ 10 companies. they range from ~80 USD (eg XSPC) to 120 USD (eg watercool) for single GPU blocks.
Rotaries have like ~ 3 companies making em'. Plus it's the focus product of 1 of them and that company dominates the market. For the other 2, it's a sort of side business.
