Reusable fittings

[Sweden-Art]

Sorry, I have to take back my statement . I will blame on the change of language (and maybe I should have read the whole thread). Ok, now I know what you mean with reusable fittings. I was always thinking of what you seem to call Plug-In fittings.

Ok, the "reusable fitting" (Screw in fitting for me) I would not use any other hose then the manufacturer recommends.

If you want to use a Plug-in fitting that works with any standard hose can look here > http://cejn.com.sg/upload/download/pdf_catalogues/610_WEO_Catalogue-english.pdf

Okay Sweden Art, I see what you mean. That catalog you posted is some neat stuff. One thing people don't realize is that here in America, everything you buy comes with a free lawyer just waiting to be taken out of the package.

you hit the nail on the head Wayne County ... most of these people have no idea what happens when you are called in by workmans compensation board to testify as to why something happened. I've been their twice and it's hard to look at the widow and tell them that if some one had spent the extra $20 he may still be here.
Why risk an accident that can be avoided by not doing it right the first time, most times the second chance comes with a painful reality..

That's the sad reality. Everything is fine until someone loses an eye. You don't need seatbelts either, until you are in an accident.

Keep spinning that cylinder and pulling the trigger.Oh, BTW, I have sent many people over to Ken at DHH. It is not my product, I don't make a nickel off of it.

yeah,40 yrs experience don't mean a thing

You got that right. You all have answered my question.:thumbsup: Thanks

I am with WayneCountyHose...Do not mix and try to match fittings and hoses with out EXACTLY KNOWING what you are doing!!!

Example SAE100R2AT 1/2"

Weatherhead 1/2"
H425 OD 28/32"
H245 OD 26/32"
H104 OD 27/32"

Aeroquip 1/2"
FC212 OD 0.88" (28/32=0.875")
FC510 OD 0.80" (26/32"=0.8125")
GH195 OD 0.87" (28/32=0.875")


etc etc...the list goes on, and there are small differences in Outside Diameter.
The "cheap Chinese discount hoses", might not even have an accurate number on OD....so it might be hard to find "usable reusable"...

Different outside rubber thickness and quality, requires different design and size of the threads inside the sleeve.

Many of them can be crimped with the same fittings but different crimp diameter will be needed.
A reusable fitting can not adjust to different OD's, You have to use the one manufacturer recommend.

If hose have larger diameter than the recommended for the fitting, it will compress the inside of hose a few 100's of an inch. Then you will fail to screw nipple to the bottom of the collar or sleeve, and if you do, it can cause such stress on neck of nipple so it breaks at the wise, or later when installed.

If hose have smaller diameter than recommended for the fitting, hose can start turning in the sleeve when screwing (screwing up outside rubber) in the nipple. This will always end up with the hose disconnecting from the fitting when pressurized.

Ive looked at outside diameters at different places that are interchangable with weatherhead h42504 hose. and they varie less than 38/64" of an inch. I reckon thats close

 

[Kitz]

The hose i am wanting to buy and brand of reusables do interchange.

 

[AKKAMAAN]

they varie less than 38/64" of an inch.

thats quite a lot...more than 1/2" .....LOL...I give you a chance to edit your post....

 

[Wayne County Hose]

I don't know how many times I have to state the following. The standards apply to the ID and OD, not what is going on in between. What is the measurement from the outside of the wire braid to the outside of the hose? Now how about on the ID side? Keep spinning that cylinder. Sooner or later, POW!!!!

I know Kenny. I don't know why I still post here.

 

[Kitz]

Outside diameter is supposed to be .596. The only hose i can get [ which it says it interchanges] Its outside diameter is .594 IS That ok Simple Question

I meant 1/64

First, the small differences in the moninal published OD are literally meaningless. The SAE standard allows a manufacturing tolerance of +/- 0.040" from the nominal dimension. Each hose manufacturer selects a nominal and then uses a typical OD tolerance of +/-0.030" to manufacture the hose to.

The first key is to make sure the hose style matches your fitting style. IE if you have a 100R2 fitting then you need a 100R2 hose. A SAE 100R16 hose will NOT work in a 100R2 style field attachable fitting. It is not simply an OD issue but how the wire will react to the compression of putting the fitting together.

Second, you need to use common sense. Field attachable fittings are NOT tested to the same standard that crimped on fittings are to begin with. Manufactures are required by law to test the hose and fitting for suitability. This does not mean that it will fail, but it means that if you use a combination that has never been validated, you are adding risk to yourself. The more critical the application the more care you need to take. If you could get hurt or someone else could get hurt if the hose fails, then let a professional do it. Doing it yourself and saving $10 is a high price to pay for a missing arm or a life.

Some people think that the only reason a manufacturer does not authorize you to put any fitting you want on any hose is simply to increase cost or force you to buy their product. There are more than forty different manufactures of SAE 100R2 hose that sell in North America and about 60 different fitting manufactures. There is just no way you can test every possible combination. The SAE charter does not allow them to write standards that "restrict a manufacture from making product but to provide general guidelines for suitability and use." So if you choose to mate two different companies products, you are adding risk to yourself, please make sure the risk does not cause danger to yourself or anyone near you.

I know Kenny. I don't know why I still post here.

:mur:....I hear ya.....I try not to look in the hydraulic section sometimes cuz of this stuff.....

It all depends which side of the fence you're on.....one side tries to save time and money doing "Disney Mouse" repair work, and the other side is trying to earn a living doing it the right way (taking on the liability when the stuff hits the fan)

I will not risk the liability involvement to open my myself to save somebody else a few bucks........heck, a $25. sale of the wrong advice/materials could potentially be someone elses windfall $$$$$......likely the lawyers.....!!...

Just an observation. I have never had a hydraulics vender/hose guy offer up any guarantee or warranty on a hydraulic product. Is this just assumed or is it a fact that the parts are guaranteed by the manufacture, and the labor that went into to hose assembly is warranted by the shop. How about a customer that wanted a new fitting on his hose. Is there any warranty on that application?

I can agree that manufactures have tested some of their parts and can say that the hose and fittings are guaranteed if made from the same manufacturer.

I have seen some of the hose guys make up hoses, and I don't remember seeing any micrometers utilized to measure anything. It just appeared that they looked at the fitting that needed replacing, and took it off the shelf, cut the old fitting off and crimped the new fitting on.

If you use a gates hose, and you don't have a certain gates fittings, do you use a similar product from another manufacturer?

I believe in being as safe as you can, but how about the reusable fittings. Is the liability placed solely on the user. I have used them and some people on the forum have used them. I would be curious if the makers of reusable fittings also make the hoses specified for use with the reusable fittings.

Don't need no arguments, just the facts only please.

Ok what hose should i get for a 425N Eaton reusable fitting. Of course i want the right stuff. I aint worried abought cost of hose. I just cant find weatherhead/eaton hose prices online.

JJ, you buy reusables, you are on your own. Just the way it is. I have no control how the hose is assembled. I have no clue what anybody did once it left my shop. I don't measure every crimp but do maybe every fifth or so. After don't it a while, I know how it should look. I have warranteed many a hose assembly. Even if it was user error. Just good business.
