I'm going to say yes. Yours looks a lot like Mark's on reply #11 & I believe his is dated the first week of Feb. of 69. What are the numbers to the left of the 5/8 or to the right of 1031, and what is the build date of your car?

Guys, Nice pictures. The larger"1/2" hose hose fittings look to be stamped with the "Weatherhead" logo.
z28z11, can you measure the insulation length on the shorter hose coming off the muffler? George.

I'm thinking those are foot markers on the hose, similar to whats put on wire to indicate how much has been used, or how much is left, put on there when the hose was manufactured.  In his case 4744 feet, mine would be 240 feet.  if so you would expect to see another number on the hose, mine would be under the insulating cover at the condenser if it was marked every foot, and i have not seen it there (have not looked either).

There are no insulation pads left on this hose set - fittings and hose are in decent shape, but no insulation left when I bought it. Fitting is dated "1", which I would imagine means '71. Configuration is right, but I cannot find the part number listed in my '74-back printing GM parts books. I included the pics as the set is complete and an original. It also looks better than the hacked-together evap hose on my Z11. Likely a service replacement, or warranty item.
Regards,
Steve

Mark,
is it coincidence that I also have the number 240 on my 1/2" hose?

I cleaned up some more AC hoses and took pictures. The "P-7510" designates the type of hose as I found it on Chrysler's & AMC hoses also. Four digits after that are Julian date and year hose was made. I took measurements of the hose & protective insulation also. George.

Good information George, thanks!

Your attention to detail to this point has been outstanding. Are you going to replace any of these lines? If the answer is yes, have you decided on a company/manufacturer for replacements?

Marty, I am going to replace all my rubber hoses using my original aluminum tubes. In the process of having the aluminum crimp ferrules made and have sourced the correct crimper. I am probably going overboard on this but I would like it to look original. I will keep you posted on my results. George.

Here is a link to 91 photos I took 4-5 years ago when Rick of Rick's First Gens owned this 14k mile 04C 1969 RS/SS 350, with AC

James - Excellent pics/reference of this '69 L48 survivor. S. Shauger has it now (aka paceme).

Thanks for sharing!

Well I can finally give you an update on my 4 month AC hose restoration project. It started out by going to a couple of well-known AC restoration companies. They do excellent work but had to use steel ferrules not aluminum as original. The crimp was close but not exact. I cut off my ferrules and machined up new ones from aluminum stock to weld back onto the factory tubes.
I looked all over trying to find crimp dies like the original “Weatherhead” crimp. One local company came up vary close but the crimp was too thin in height. Then I bought the closest dies I could find, welded up the jaws and reground them to the correct height and diameter. I figured I was in this project this deep so I bought a used Parker MiniCrimper so I could test out the dies and crimps myself. After welding the new ferrules onto the original tubes I was ready to crimp. The crimp looked good but the ferrule had small cracks in it. Many tests later I realized when the factory welded the ferrules on they heated the ferrules to a higher temp an annealed (softened) the fitting. I annealed them and finally got a nice crimp. I replated the yellow cad fittings and went to town on two sets of hoses.
One #10 hose on the muffler would not fit in my crimper or other local crimpers. I removed the hydraulic cylinder from the MiniCrimp to use the base in our big press. I had to make up a taller pusher tube to accommodate the muffler height. Kind of a Rube-Goldberg setup but worked great. I found out most new barrier hose is a smaller diameter and requires smaller fittings, but Goodyear makes a correct barrier hose to fit the older fittings. The assembly manual only shows one sleeve on the #12 hose but both of mine and other original hoses had two 7” sleeves. Just glad to have finished this today.George
