Anyone ever seen a hose barb like this?

[Pullstart 62,897]

It’s a two piece hose barb, with an o-ring.  I thought it was broken when the barb twisted and the body stayed put!

Cleaned up and assembled…

 

 

[ri702bill 8,324]

To allow the hose to rotate??

Seems you have to assemble the hose on to seat against the fitting, then screw the fitting in??

[953 nut 55,247]

           Was there a sleeve that would go over the tubing and be compressed by tightening the nut?

[WHX?? 48,818]

That's bizarre... what was it on? Guessing low pressure? Barb looks short?

your guess is good as mine, but I don’t think it would make any difference.

we’ll find out if it works….  I’ll only keep 1/2 gallon or so in the tank to see if the o-ring holds up.  My guess is maybe for a welder, the argon tube?

@Pullstart  2 different  fitting types ,  HOSE BARB  TO  PIPE THREAD FITTING , that first picture threw me off , did not see any threads to screw into the  pipe fitting .  hose barbs come 2 ways  , barb to barb  or  barb to  male / female  end finish . good spot for a SWAGE LOCK FITTING , available  in male or female .

I 've seen them on some boilers on the air switches and sensors. Gasoline will probably turn that o-ring into oatmeal after a while.

@Pullstart https://www.bing.com/search?FORM=UP97DF&PC=UP97&q=swage+lock+fittings  lots of options / ideas , used to work with a pipefitter , always a way out , pete

With nothing but the O ring friction holding the two parts together , It can't hold much pressure.

There must be a lip on the threaded part, and the barb goes in from the rear.

 

Has to be some application where the hose need to rotate.  Never saw that before myself.

Valid statement. Would probably happen in a matter of days.

 

I give it a week... maximum...

Now I see it.      Probably lost too many brain cells.  Eighty years of washing up in gasoline, lacquer thinner and acetone could be taking it's toll.

I’ll let y’all know how long it lasts!

You could always replace the O-ring with NBR or some such that resists the ethanol.

I’ve resorted to pure fuel, if that helps.  No corn mash in my tanks 

[wh500special 2,184]

It’s a swivel barb fitting.  Not available at the hardware stores but available in catalogs.  It allows you to preattach the hose without it rotating during assembly or

is used to allow some repositioning once installed.  We use them once in a while on machines where it’s hard to get a hose into place after assembly.  
 

Never had the o-ring leak as far as I know.

Since thats a speciality fitting i would bet that O-ring is something better than plane rubber. Probable Viton or NBR which should be fine for gasoline.

Me thinks it’s a drinking water fitting.   You can view a similar one in the catalog of a famous hardware catalog by searching “barbed swivel fitting and looking through the pictures.

Ya think?

 Nah, probably due to measuring pressures with Mercury manometers for 50 years.      Or maybe melting lead on the kitchen stove  and pouring jig heads and sinkers.
