Rotating air fitting - hose reel

[wbrian63]

I have no idea what to call this device.

I have a Lincoln hose reel in the shop. Attached to the hub of the reel is a fitting that allows the hose on the reel to connect to the supply and still rotate freely.

It attaches at the back to a 1/4-20 or 5/16-18 stud that's part of the hub shaft. Has a 3/8 FIP entry in the end of the axle, and another 3/8 FIP hole in the rotating hub.

It's leaking air around the seal between the fixed and rotating portions of the shaft.

I would figure this would be a fairly common article, but I've scoured McMaster-Carr, Graingers and a number of online sites without luck.

Lincoln's hose reel site doesn't offer much help in the way of parts lists, etc.

I would think it's a fairly generic part. The cheap-o reel I've got across the shop has a similar fitting.

I would bet it can be rebuilt, but I haven't taken the time to take it apart and see.

Any ideas on a source for a replacement?

I just repaired mine. Very simple generic o rings in the ones I've got, old american made industrial ones.

You see these fittings on fluid dispensing reels as well.

Thanks - I guess I'll break out the snap ring pliers and give it a go.

Nothing to it, little bit of lube on the new o-rings and you are good to go.

be sure to put a little grease or iol on them when you re=assemble

Thanks for the suggestions.

The first item is kinda like what I need, except too small, and can't be fixed to the hub of the reel without some "adaptation", plus I'm not sure it was designed for the amount of rotation that will occur in a hose reel - more like for an air tool.

Second has the same issues as the first.

I do appreciate your suggestions.

What it sounds like your describing is a 'rotary union'. Use that as a search term and a lot will show up. If you rebuild the old one with new O-rings please get a lube that is compatiable with the o-ring. Parker O-lube is one of the good ones.

If you need to replace the whole fitting, those are available as service parts from Lincoln. Just call them.

it is called a swivel

I've got some Dow Corning lube that looks like semi-clear lard. I think it's packaged as o-ring lubricant. I'll make sure I use the right stuff.

Thanks for the suggestion.
