ethylene glycol swivel fitting
ethylene glycol swivel fitting
(OP)
Hi,
I'm looking to design a piping system for about 4 coolant lines (3" dia each) carrying ethylene glycol to a shelter resting on an Azimuth turntable. Because the turntable will need less than 3/4 of a rotation, I want to stack 4 swivel fittings over the center of rotation. The expected Pressure requirement is ~200 psi. I was thinking a hydraulic-type fitting might be a source. Any idea where I might find this type of fitting? I prefer to avoid wrapping flexible hose. This is outdoor & must fit thru a 48" dia hole. Does this sound like a commmom application?
Thanks

You can find products similar to theirs on McMaster Carr's website, mcmaster.com. They have some (although only rated for air, not water/glycol) with 4 independent connections in one union.
Two cautions: 1. get epdm seals if at all possible, and plan for leakage. 2. Your application is one of reciprocating motion - try and get a union design that has all fitting threads aligned perpendicular to the axis of rotation, so that the fitting threads won't back off over time.

The size 3" lines would make hoses fairly stiff. There are swivel joints made for tanker and rail car loading arms in that size that would be a good fit for your application.
These vendors also make the fueling hose swivel fittings that you would see at gasoline pumps:
