That is all I have used for the past several years. They work fine, and are truly reusable. I have a couple that have been taken off, the hose shortened, and reinstalled three or more times.

Ends for one-half inch and smaller two wire hose require only an adjustable wrench to install. The three-quarter inch and larger hose requires a vise to hold the hose while you screw on the outer part of the fitting (which has a left hand thread that bites into the outer cover and wire of the hose.

Cut the hose with an abrasive blade. I made a simple jig for a circular saw to give square ends, but I also cut free hand with a 1/32" thick 3" diameter cut off wheel on an air powered cut off saw.

Be sure you clean the dust from cutting the rubber and reinforcing wire from the hose before installing the end. Parker-Hannifin approves mineral spirits to clean the hose. Just run a bit through the hose and blow it out with air.

They are obviously more convenient than crimped fittings (unless you have a crimper), and you get exactly the length of hose you want. The only disadvantage I know of is that they are a bit longer than crimped fittings so the hose can't start bending as close to the outlet as it can with crimped fittings.

They work great. Oil the outside of the hose before threading on the first piece LH thread btw. Lubricate the second piece as well. Don't pull them up tight leave about 1/16" space on each before dead tight.
They cost more than crimp fittings although when you pay the crimp labor charge it is getting close. There is less of a selection of ends then crimp type so sometimes by the time you get it right the cost is more. But the ability to do your own is priceless. Check out Discounthydraulichose.com whoops ebay item is DHH.

Thanks for the info guys. :) If these things really work, I'm sitting here trying to figure out why anyone would use anything else? :confused: The cost savings could be staggering over time... unless, of course, you happen to own a crimper!!! ;)

I buy all my hose ends from DHH. The hose ends from DHH (and most other places as well) come without instructions. But the Parker-Hannifin web site has good directions on installing them. If you can't find that, as 6SunSet6 said, cut the end of the hose square with a power abrasive saw (a "rod" type hacksaw works, but not as well), snip off any wires that are not cut clean, run mineral spirits through to clean the hose, blow it out with air, dip the hose end in hydraulic oil, screw the outer fitting (LH thread) on the hose all the way, the back off 1/2 to 1 turn to leave room for the hose to expand, and then screw the inner fitting into the outer fitting until it bottoms out.

Once you have done a few, it is a five minute job on smaller hose and ten minutes on the larger sizes.

no problem at all, there are great, but expensive.

Well, I must admit it: This is a real wake-up call for me. If these work so well, it amazes me that anyone would ever use anything else? The ability to make immediate repairs almost anywhere for peanuts has got to trump any slightly higher initial cost. :cool:

Crimped, made-to-length hoses are not exactly cheap or convenient around here. In fact, they are anything but! :rolleyes: Unless someone here suddenly comes up with a horror story or two, I believe I've just found a perfect solution to all of my hydraulic hose needs. :)

Well, just as everybody else has said, these fittings are great. We have used them for about 7 years now, never a problem. And they are truly great for in the field repairs. I'm in the process of refurbishing my Case 310 dozer. All new hydraulics, pump and hoses etc. I want the hoses run my way, not how a hose guy wants them run. Don't want to worry about if the guy crimping the hose gets the fitting aimed in the right direction. Not up to buying my own crimper yet, although the crimper isn't all that bad, it's the dies that cost all the $$$$. Anyway, the reusable ends are the way to go.:cool:

Excellent Brian... thanks for yet another positive review! I don't know how I managed to miss the boat on these for so long... but no longer! I order my first batch today! :)

Ugh. I have to admit, these things are a hosemans worst nightmare. They do work very well. I have sold a boat load and have never had a problem. I do warn you, however, not to deal with Discount Hydraulic hose. I used them for a couple things about 2 months ago. I paid by credit card. They never shipped. They kept claiming my fittings were on backorder. I ordered these on July 24 and have yet to receive my fittings. I also have some of their hose here. It is cheap junk with many fillers in it instead of pure nitrile. Just remember that with hose as well as anything else, you get what you pay for.

I have ordered over $500 from Discount Hydraulic. A couple of backorders but everything showed up pretty quick. Don't know about the hose but it is marked with the standard specifications. That's my experience. They have a much wider variety of fittings than Northern Hydraulic or the Surplus Center. Makes for a much neater job with the least number of fittings.

Is there anyone else with an internet site for hydraulic fittings?

Thanks for the input. I must say that I am a little surprised at the negative comments about DHH. Their feedback on eBay is 99.8% positive: only one negative (related to an incorrect and later refunded shipping charge) out of nearly 600 customers and well over a thousand orders. Can their hose quality really be that bad? :confused: If you have a better quality source of bulk hose, please let us know.

The fittings that you saw on Ebay, are for an R-2 hose that has two layers of steel. I believe the outside diameters are different for the different hose, R1, R, and R. So if you have an R hose, these fittings will work just fine.
I plan to buy the R-2 hose specifically for use with the R-2 fittings... so everything should match-up fine. :) My only hang-up so far is that I can't find these do-it-yourself fittings with 1/2" male NPT ends for 3/8" hose. Seems to be the only type I need that DHH doesn't have. Anyone know why??? :confused:

Most companies are very careful to keep ebay customers satisfied to keep their ratings up. I did not purchase thru ebay.

You should only install hose ends on hose that the end is approved for. A Weatherhead end should never be used on a Gates, Parker, or DHH hose no matter what the 100r# may be. When I crimp an end on, the crimp diameter is measured to the thousandth of an inch. I am allowed to be .010" off. Hose wall thickness varies between manufacturers. I have DHH 3/8" hose here and it is .1" thicker than Weatherhead. DHH uses more fillers in their nitrile, Weatherhead uses a purer nitrile.

So, for your own safety, never mix hose and fitting manufacturers.

Another very good source... but I still don't see those 1/2" male NPT "do-it-yourself" ends to fit 3/8" 2-wire hose. Seems that should be an extremely popular type for aggie use given that most of our rear remote set (quick disconnect) couplings require 1/2" NPT female hose ends. :confused:

Wayne County Hose is surely right that the hose ends should be of the same manufacturer as the hose. However, I have mixed and matched for years and (knock on wood) never had a problem yet.

You are not likely to find a 1/2" NPTF male 3/8" hose fitting for this reason: The ID of 3/8" schedule 80 pipe is 0.423", which is larger than the 0.375" nominal ID of the hose. Therefore, the 3/8" pipe does not restrict the flow more that the equivalent length of 3/8" hose (ignoring turbulence at connections, etc.). So there is no "hydraulic flow" reason to have pipe fittings larger than the same nominal size hose. So, the solution is to use a 1/2" to 3/8" Sch 80 hex reducer bushing to fit the 3/8" hose end to the 1/2" quick connect.

FYI, JIC hose ends often use a fitting size (JIC flare, etc.) two numbers larger than the hose size because in fact the ID of a -6 (ie, 3/8") JIC fitting is smaller than 3/8" and therefore offers more flow resistance than a 3/8" hose. Thus, all the 3/8" hoses on my Kubota FEL have -8 (1/2") JIC fittings.

The few problems with DHH that I have had were always corrected promptly.

Thanks for the reply. I understand that there is no good hydraulic flow reasons to have such an end fitting... but there are certainly some practical physical reasons for same when it comes to our aggie machines. I understand that I could use any of a number of other end fittings and adapters, but I prefer not to do so unless absolutely necessary. As folks always have told me: Minimize the number of hydraulic fittings for best results! :)

But back to the point/question from a little bit different angle: Why can I buy "crimp-on" type 1/2" male NPT end fittings for 3/8" hose just about anywhere I look or go... but not those "do-it-yourself" type 1/2" male NPT end fittings for 3/8" hose??? :confused: That's my real confusion! :eek:
