Hose crimps

[BlacknTan]

I've spoken to the tech at DHH.

They're good people, and as helpful as they can be. They reiterated that they could also not guarantee a job with fittings from others. I can understand that completely! I have zero problem with the frolks from DHH.. I guess my problem stemmed from the fact of my inexperience, and the idea that I was worried about the orientation of fittings on both ends of the hoses. I also just came to the realization of the difficulties in cutting the hoses to length without the proper equipment.. Maybe I did not give the whole question of hydraulics the respect it obviously deserves.

I'm only pointing a pitfall that I ran into. Perhaps if after reading the million posts that I read before embarking on this job, I would have done things a bit differently...

I guess the old adage applies here... "Too soon old, too late schmart..." Or.. "If I knew then what I know now..."

It's been a good learning experience...

What a great attitude BnT, I applaud your outlook. If more people in this world would take responsibility and not blame others it would be a better place to live.

I work for an off-road OEM (and previouly worked for CaseIH, Hyster/Yale, Lull/SkyTrak) and whole-heartedly agree that you should not mix brands when dealing with hose ends and hose. Even within one vendor's products (Parker for instance) you have to match a particular hose with one or two series of hose ends.

On the other hand I am much less fanatical about the crimper --- as long as you can guarentee the correct crimp dimension --- which depends on the crimper design. Some crimp to a pre-set dimension while some are variable.

I'll start by saying I work at Discount Hydraulic Hose. Some of you have probably talked to me if you've done business with us.

The two most obvious critical issues when selecting hose and fittings is (a) using the right fighting with the right hose, and (b) crimping that fitting to the correct dimensions according to the fitting manufacturer.

We've been making hoses here for decades, and we don't have a problem interchanging brands of hose as long as both hoses meet the same industry-standard SAE specifications. For example, you can swap SAE 100R2AT hose from one manufacturer for SAE 100R2AT hose from another company without a problem. As long as you use the correct crimp specifications, you'll be fine. If you change to a hose that meets a different SAE specification or a special "brand exclusive" that isn't made to SAE specifications at all, you'll need to make adjustments. Often these hoses handle higher working pressures or have special features like tougher covers, etc. If you're using one of these special hoses, you are best to stay with the same manufacturer's fittings because SAE specifications do not apply.

Of course, the fittings are not right if they aren't crimped properly. A fitting crimped on SAE 100R2AT hose will require a different crimp diameter than the same fitting crimped on a SAE 100R16 hose. You should always consult the manufacturer's catalog or product literature to determine the right crimp diameter for the fitting and the hose you are using.

If you have an adjustable crimper like the ones we sell, you can dial in the precise crimp diameter for the hose and fitting you are using. Our D100, D165 and D205 adjustable hose crimpers can be set to precise increments as small as one/tenth of a millimeter, so you have a lot of flexibility to crimp fittings from a variety of manufacturers.

If you have a non-adjustable crimper, like many of the Parker and Weatherhead models, you have fewer options. You can only set your crimper to preset diameters, so it's best to use fittings from the same manufacturer, or fittings that you know are interchangeable. Many fittings are NOT interchangeable, so if you're unsure, ask before you buy.

For the record, Braided Hose Fittings are interchangeable with Weatherhead U Series. The are definitely not interchangeable with Parker fittings.

Most of our other fittings (W Series, JJ Series, etc) are not interchangeable with other manufacturers. You need to have an adjustable crimper that you can set to the correct crimp diameter in order to use these other fittings.

I hope this clears up any remaining confusion.

I'm guessing this may be deleted.
But you brought up a point I've made many times about crimping hoses. They are manufactured to SAE standard and knowing that you should be able to mix and match knowing these standards. I get real tired of people who think making hydraulic hoses is some sort of rocket science left to the experts and you are charged accordingly.

Thank you for pointing out the obvious so eloquently.

About the only correct part of his whole post.

You forgot the part in the manufacturers catalog which states to never mix and match manufacturers hose and crimp fittings.

If you have an adjustable crimper like the ones we sell at Discount Hydraulic Hose, you can dial in the precise crimp diameter for the hose and fitting you are using. Our D100, D165 and D205 adjustable hose crimpers can be set to precise increments as small as one/tenth of a millimeter, so you have a lot of flexibility to crimp fittings from a variety of manufacturers.

Thanks for proving my point in my earlier post. Another shameless plug. I thought advertisers had to pay to post info like this?

If you have a non-adjustable crimper, like many of the Parker and Weatherhead models, you have fewer options. You can only set your crimper to preset diameters, so it's best to use fittings from the same manufacturer, or fittings that you know are interchangeable.

Umm. We do have many options. Like crimping hoses that won't explode on people.

For the record, Braided Hose Fittings from Discount Hydraulic Hose.com are interchangeable with Weatherhead U Series. The are definitely not interchangeable with Parker fittings.

So says DHH. Weatherhead says no. Who is a bigger name in hydraulics and who is a more trusted name in hoses? Need I even ask?

Most of our other fittings (W Series, JJ Series, etc) are not interchangeable with other manufacturers. You need to have an adjustable crimper that you can set to the correct crimp diameter in order to use these other fittings.

I hope this clears up any remaining confusion. If anyone has additional questions, feel free to ask them here or (for a quicker response) send an email to support@discounthydraulichose.com. Someone in our customer service dept. will be glad to assist you.

And the rocket scientist has chimed in.
I would like to hear from ANYONE who has had DHH hose "bust", not leak, but actually blow apart. I'm guessing if this were a common event for DHH they wouldn't have been in the buisness for over 30yrs. And how many Parker or what ever hoses bust on a daily basis. Especially with stuff that is using 3000psi or less.

Nope. Not a rocket scientist. Just another idiot on this big rock revolving around the sun trying to put food on my family's table. In my shop I have multiple hoses that "busted" from putting one makers crimp on another's hose. Yes, these hoses blew apart and swung around like a whip. Maybe not DHH product, but even better name brand stuff. And yes, when you do mix manufacturers products, this is a common event. This comes from Weatherhead who has been in business a bit longer than 30 years.

Ya' know... I didn't start this thread to bash anyone, and I hope that it doesn't end up in a melee!
I merely wanted to point up some of the pitfalls involved in a project like adding remote hydraulics.. a subject that i see many neophytes such as myself have undertaken. I wish when I was doing the hours of research for this project that I had read a thread that pointed up the myriad of hoses and fittings, and all that's involved in crimping them to get tight, and most importantly, safe connections.

They say that "Knowledge is Power" and, if that's true, I'm just a bit more powerful on the subject than I was before..

I wasn't entirely sure of the parts I wanted or needed, so in my case at least, I would have been better off dealing with my local hydraulics shop, where I could have picked the counter man's brains to my heart's content.. For those that have more experience and knowledge than I, the avenue of ordering online might be just fine...

I have no problem with anyone, so please, no personal attacks.

 

[wedge40]

what I have learned from these hydraulic conversations is when it comes to SAE standards and hydraulics they dont mean squat. And from this I should take all SAE standard with a grain of salt.

Sorry didn't mean to make this a bashing session, but again I haven't heard from anyone other than one person (another hydraulic shop) about busted hoses.
