Reuse hydraulic hose?

[AKKAMAAN]

IMO, posting this type of image without a caveat is not in good taste...I am not disturbed by the content but some folks that aren't expecting something like that might just lose their lunch...

I suggest using a link to images not everyone may not want to see with a warning about the content...

Sorry pal....didn't know you were at lunch....:thumbsup:

Do not "spin the internet-chamber" while eating...

Sorry pal....didn't know you were at lunch....:thumbsup:

like I said...it does not bother me but it might some...

the images should be removed IMO... it's no different than posting pictures of roadkill etc...

I have to agree with guys that reuse, if hoses look good except in situations where some one could be endangered from a flaw, such as some one in a bucket truck. Save the money.
I also agree with guys that have shop that repairs hoses to say take it somewhere else.
I have been waiting for a worn hose to break on my loader for 2 years! Untill then I am going to get the goodies out of it. I have also had new crimps from a shop that failed. So keeping yourself out of danger is a consistant practice.

I learned something new today, didn't know that fittings were designed to mate with specific hoses. I always thought that 1/2" hose was 1/2" hose and a 1/2" fitting fits 1/2" hose. I'm very leery of that 2000 psi trapped inside the hose. I want it to stay there, kinda like the genie in the bottle. As long as it stays trapped, it'll work for you. If it gets out, bad things happen.

Anyway, I have a 1 year old hose (so it's "new" from the manufacturer) I want to tap into to add a diverter circuit for a grapple on my FEL. Hose type is unknown, it's whatever JD uses. My concern was whether the oil would prevent the fitting from grabbing the hose tightly enough. From the posts, it appears I can have a shop cut the hose in half and put fittings on it and expect it to hold as well as a hose without the oil having been run thru it.

You cannot just cut into a hose and add a tee. You could add a selector valve in the curl circuit, using a selector valve. With everything connected correctly, the curl will work normally. When you flip the switch on, the fluid is now going to the grapple.

I'll agree with all that with one exception. If I am making the hose and selling the parts & pieces, the decision to repair or replace AT MY LOCATION is mine, not yours. You can always disagree and go elsewhere.

I love how these guys that don't deal with hoses and hydraulics for a living know more about them than us that do. Nicely put Rick.

No one is suggesting the use of bad hose. Those of us who reuse hose have been quite clear on that so your point is just rhetorical.

The question is whether to always or almost always use new hose on CUT related hydraulics. If the answer is that you always need new hose "just in case" then that same pricinple might be applied to the entire tractor. Why not replace the entire tractor each time a hose leaks. Never know when the next hose on that used tractor is going to blow, right?

The reuse of good condition hoses is just a practical economic matter and we make similar judgments and beneficial compromises in all areas of life daily. Do you replace a car tire with a simple puncture or repair it?

I don't need a robot programed to say "replace it" when I go to a hydraulic shop. I need an experienced knowledgable mechanic who can help me assess condition and also understand the risks associated with my particular application. The final judgment is mine but I'd like to trust that the mechanic is not just giving me a knee jerk reaction.

I'll agree with all that with one exception. If I am making the hose and selling the parts & pieces, the decision to repair or replace AT MY LOCATION is mine, not yours. You can always disagree and go elsewhere.

Yes. And of course yous know more about the sevice of hoses on our machinery than we do.

Why wouldn't they know more about the hydraulic hoses on your machine? You'd expect an equipment mechanic to know more about your machine than you do. I'd expect them to know more about hydraulic hoses than I do, and I am sure I have built and seen more hydraulic hoses than most tractor owners here have.

I think the point is more that while some shops may be extremely conservative because of liability issues (man lifts etc) those of us who own CUTs know how we use them and can pretty easily understand the consequences of any particular hose springing a leak or breaking. If my BH dipper stick hose breaks or leaks, I know that it is never closer than six feet or so to me under load and that it is covered with a nylon sheath which will diffuse any spray as well as running on the opposite side of the boom. Under those circumstances I might feel perfectly comfortable using an old hose while the hydraulic shop thinks only of worst case, life on the line, scenarios (as noted by a couple of the guys here).

Just like a patient can know their own body better than the local doc, we CUT owners can sometimes make more informed decisions than an expert sitting in a hydraulic shop can without our input. Nobody is claiming that we know more than the hydraulic guys but that doesn't necessarily translate to deferring to their standard policy as the best decision for us. They can refuse of course and I would certainly understand that the liability and insurance issues they deal with might prevent them from ever reusing a hose but in that case I would thank them and take the business elsewhere.

I wonder if you missed the [now] highlighted word when making your response. The particulars of the hose, its service, and its failure that would justify reasoned choice in renewing the connection. To say that they know more about hose is certainly true, but I dont credit that as an excuse to flip entirely in one direction regardless of the specifics. You can be sure that there is a mixed hose and connector combination out there that actually works better than the one specified. Every mix is not definitively wrong.
