Has anyone done the homework to see what type of hose works good for the
3/4 fittings. I havn't had a chance to get to the Parker Store and look first
hand. It also does not appear that code 62 fittings will work with the Cat barb flange 5f2046

I don't have my Cat hydraulic book with me, but I can tell you that many of the Cat split flange fittings do not cross to any industry standard, like code 62. It would probably be an XT3 fitting. It also takes a special press to assemble the hose and fittings.

It's been a while since I checked but I believe its "code 61" fittings that will fit the 5f2046 flange.....regular 2-wire 3/4" hyd. hose works fine.

I beleive that these are code 61 flanges and in the past I have taken the old flange halves ( the part the bolts go through ) & if you only have a flange on one end. You can crimp the code 61 flange fitting on one end & then slide the flange half over the sleeve, then crimp fitting on the other end.
Also I have been in some shops with old inventory & have seen some of these fittings but they are designed for 4 wire hose ( XT3 CAT hose ). So maybe contact your local CAT dealer & find out if they have any old inventory still kicking around
But if you still have all the fittings & sleeves any 2 wire braid hose will work for example: Parker 301-12. Good luck hosing if you have any more questions let me know.

Thanks all for the input. I found that Cat calls them "captive flanges" in thier
catalog. I ended up using Parker 302 hose due to one hose was made years
ago with parker series 30 reusable (which the two hole flange is no longer
available) I stayed with the the orginal cat two pieces on the others.
The partsman at Cat told me that Cat pricing was comparitive to Parker
but I did'nt compare specific prices. Nice to know for future reference.
Seems like fittings have a bullseye on them. I scraped a tree last year and
the knotted burr was a direct hit on a blade cylinder fitting. It snapped like
a tooth pick.

If you need some 3/4" two hole flange fittings let me know I may be able to help.

In Lincoln Nebraska is where I got some new ones for my little D2.
