high speed rotary couplings

[JOHNMCC]

Can anyone tell me where I can find a high speed (5000 RPM ),
high pressure (1000 PSI), single path hydraulic, rotary coupling? I'm not having much luck with my local hydraulic suppliers.
Thanx for the help!

Try either Deublin or Duff-Norton. Joints of the type you are referring to are known as rotary unions, whereas swivels are for quasi-static situations.
