Rotary Coupler

[Speedy]

I have an application where i want to feed 4 seperate water pipes and a common return to a table that is rotating on a central shaft. I require a ROTARY COUPLER that will fit on over the shaft, approx 100mm dia, and will feed the water through as the table rotates.

I did a search but could only find ones for hydraulic feed.

Any help gretaly appreciated.
Cheers,
Speedy

These are often referred to as deublin unions. Seems that Deublin has thier own website.

Madmango, thanks very much for that!

My problem is that there is a solid shaft in the middle of the table.

Are there any ring type rotary couplers that allow for a shaft to fit up through the middle?

Cheers,
Speedy
