Do these work???

[Wayne County Hose]

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?

Do these work? Does anyone here use them?

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.

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? If you have a better quality source of bulk hose, please let us know.

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???

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.

Dougster:

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??? That's my real confusion!
