Rotating joint

[algee]

I have an application that requires using a rotating joint in a water pipe system. Existing 'Rotary Unions' are large and expensive, and probably oversized for my application (slow speed and moderate flowrate, not full rotation). Does anyone have any suggestions on a different kind of swivel or rotating joint? Thanks -

pipe size/operating pressure rating might be a problem

Also try Johnson Rotary Joints or Barco Swivel Joints.

You should define the flow, pressure and pressure if you want good help.

How about using a flexible hose section.

These may be two big for you, but elbows used on cement pumps are very cheap around $A100 for a 100mm one.

Thanks for all the advice. Superswivels is a good option. EdDanzer, apologies for not being too specific. Flow conditions are room temp water, 3/4" tube size, approx. 8 gpm, low pressure (~5 psi).

Try using a sprinkler head, or similar plumbing from a hardware store.
