Reuse hydraulic hose?

[TRR]

If a hose has been placed in service and has had oil run thru it, if it needs to be made shorter can the end be cut off and a new one put on, or does the oil make it to slippery for the fitting to hold onto, meaning I'd need to replace the hose.

If the hose is still usable , not cracked, no wire showing, and no problems before, then you can have new fittings installed.

It should be OK. As long as the wire braid is not falling apart from bending. The standard construction cross section for hose is 100-R1. which is a inner hose and a wire braid covered by a outer rubber cover. The crimp fitting grabs the inner hose and the wire braid and cover so it's a pretty strong assembly. I've cut up long hoses and made shorter hoses many times.

Edit
I had my SAE numbers incorrect from dealing with so much 100R7 hose from Synflex in the past. I meant 100R1 which is the garden variety hydraulic hose construction for compact tractors.

Huh??

I will assume this is a new hose? If so-and you go back to the same shop you should have no trouble getting them to shorten it up a bit. If it's an old ratty hose then forget about it.

I've had a new fitting put on a used but good condition hose. The guys in the hydraulic hose shop didn't blink when I asked so I don't believe it is uncommon.

Just curious how many of you guys turn down business because you don't have the same brand fitting/hoses? I think that most people take a hose in the hyd shop and tell them to fix it, and they do it. I have yet to hear one of them say something like this, I am awful sorry but I can not match up hose to fitting, I am forbidden to mix and match.

Do you all really think the guy using the hose even cares about matching brands? He wants it fixed. Time is money, bottom line.

The standard construction cross section for hose is 100-R7. which is a inner hose and a wire braid covered by a outer rubber cover.

Actually, SAE 100R7 hose does not contain wire or rubber. SAE 100R7 is a thermoplastic (nylon) hose with braided fiber reinforcement. It has a maximum working pressure similar to SAE 100R1AT (single wire braid). A heavier version, SAE 100R8 is available for higher pressure applications.

Because SAE 100R7 and 100R8 hoses do not contain metal wire, they will not conduct electricity as well as most other hydraulic hoses. They are often found on bucket trucks and man-lifts with an orange cover on the hose to identify it as nonconductive. This is a very important safety feature for utility trucks and other equipment that will be used in close proximity to electrical lines.

Thermoplastic is also used quite bit in sewer cleaning equipment, because it's smooth outer cover is easier to clean and slides more easily through pipes and drains.

We don't find a lot of thermoplastic hose on farm equipment. It's more expensive than wire-reinforced hose, and the benefits it offers - nonconductivity and a smooth outer cover - don't really apply to someone driving a tractor or a harvester.

Getting back to the original question,

If the hose is in good shape, you can cut it shorter and put on a new fitting, but I would take some extra care in cleaning it first. Cutting hose creates a lot of dust, and oil is a dust magnet. Hydraulic fluid residue inside of your hose will grab hold of that dust, which will eventually wind up as debris inside your hydraulic system. Clean the hose before and after you cut it to get the best results.

Your mileage may vary, but if keeping your hydraulic fluid clean is important to you, keep this in mind whenever you consider re-using a used hose.

I absolutely do turn down this type of request. If a potential customer can't understand the liability potential for both my employer and perhaps even himself if he happens to have employees that operate the equipment in question,then he can walk out the door mad as ****. It is his choice NOT to replace a faulty or damaged hose.

If the hose in question is in near-perfect condition and the same brand that I stock and sell, I will repair hoses on a very, very selective basis.

RickB ... we do the same thing.. we will not install a new fitting on old hose... if the customer wants to same 60 bucks on a hose then he can go down the road... it's not worth the worry or the liability
Hose guy... we use a LOT of 518C hose.... (we do a lot of work on bucket trucks) but i really like to use it on other projects... YouTube - Home made wood processor I like the way it lays in a bundle, the light weight, it will not wrought out like steel braid and it LOOKS COOL.... LOL .. the only problem is it will not take welding splatter very well.... DON'T ASK..... Jim

See hydraulic hose guys post. 100r7 made no sense in the post I put "huh?" Under

Well, thank goodness our NAPA isnt like that. Mostly I have them shorten a new hose that I supply when Iv had an "old hose" failure [and these usually happen at a factory crimp]. But Iv had them repair a used hose that was in good condition except for an end pinch related failure. The most key issue is that ID and OD are a close enuf match to assure a tight crimp. I have had no indication of any trouble from any mixed repair because we always verify the compatible dimensioning.

I'm sorry Larry.. but CLOSE ENUF MATCH .... isn't good "ENUF" for the business that i'm in, people depend on me doing more that CLOSE ENUF so they can go home at the end on their shift working from working on high tension power lines all day, i guess thats why i can send work like this to NAPA and not have to worry about it.

Well, there is room for both. Not all hydraulics are a matter of life or death. There is milspec if you need it and then there are the hoses that connect bits and pieces of CUTs where no one is hanging off a line fifty feet in the air.

I snagged a dipper cylinder hose from my backhoe on a tree and it caused a leak (spray) right at the fitting. Took off the hose, took it to the local hydraulic shop and had a new fitting installed on the now two inches shorter line. Cost was about $25 vs maybe $80 or more for new hose and two new fittings. No one is going to fall to their death because of that hose repair so it seems quite reasonable to me.

One size solutions do not fit all.

 

[brain55]

I personally judge them case by case. I will put a new end on a reasonably used hose. I will not put on a hose that has seen better days. If there is any cracking on the outer rubber why put a new end on a questionable hose. Or a hose where it was obviously stretched to the point of failing at the crimp. I don't respond with a flat "I won't put a new end on a used hose", nor do I automatically say "yes". If there is question of the compatibility between hose and fittings I will say so and recommend a different person or sell them a new hose. I stock and use Weatherhead hose and fittings. Being that I am mobile and have hose and fittings with me I can usually sell the new hose, but my reputation depends on me not selling something that people don't need.

I guess you guys who only work with brand new hose dont service any farmers or dont list your selves as hose repair shops. I fail to see what Liability you would be under if you installed a new end on an old hose. You just have to let the customer know that you wont warranty the hose not to burst or leak at the crimp and he can make his own determination. I truly doubt that you stand liable for a burst hose past the door to your shop which I would for sure never darken but once. Folks who claim liability as the reason to rip off a customer for additional money because he wants to sell some hose can do without my business and I suspect a lot more TBNers business as well.
Personally, I always use new hose if one burst, but to have a business tell me what I must do or not do is not going to happen. I will tell you what I want and if you wont provide the service, the I will find someone who services the customers needs not just his own.

 

[RickB]

Apparently most of you guys that read my post couldn't understand the last sentence.

For those that put a few dollars in your pocket above safety, go talk someone who has been the victim of oil injected under the skin, or someone who has has been injured in some other manner due to a hydraulic failure.

Nobody here has to accept or agree with my principles, I just don't care that much.
