the first time I ran a reduction hose it came standard on a brand new putzmeister z boom,ran it the first job no issues, 2nd job pumping slow volume control on 4 rpm 16-1700 and no grunt no nothing that baby stands up and blows about 50 ft luckily towards the lake I was pumping by,if it wouldve come my way or the pumps we wouldve been blasted,2nd time another brand new putz same thing except this was a 20 cell and was on 3 on volume control and was pouring footing no hose man same deal no grunt no nothing but one hell of a whip, that was my last,its either straight 5" or a 5-4 reducer and 4" hose,these hoses are extremely dangerous, I know some will say theyre great for ICFs and I cannot speak for the 5-3 hose cause I never used them, but look all reductions should be made in a steel reducer not in a rubber tapered hose.

please add your horror stories or praise for these hoses.

 Those things are for decorating bigass cakes or something. They sure as hell aint for pumping concrete through!!! "dogdix"

i agree 100% TT you said it cakes only!!!

i used to use a reducing hose 5 to 4 until it whipped on me, problem is there's no reinforcement in those hoses so when they clog (and where is the clog 99% of the time, in the REDUCER) they either burst or clear themselves, so when all was said and done the hoseman was laying facedown in the concrete and i didn't even have time to stop it from happenning, don't know how there constructed now but 5yrs ago when i first tryed them i think they were dangerous!! i prefer a steel 5 to 4 reducer and a 4 inch hose with 1 end and the other end cut with a chopsaw on a 45 degree angle

I don't like them much either! Ever try to beat a chunk of rock through a snake?? Finally I had to cut it off! Then it was almost too short to tie off and rack. I've alway been partial to a steel reducer,but then I'm OLD school...

I have had no trouble out of a 5 2 4 hose, I wood take one any day on a 61. You get the big hose affect with a 4" flow. But I can see what you are talking about. Even bran new straight out of the box they don't have know backbone. Should call them jelly fish hoses.

 I too have had few problems with my 5 to 4. Have I had blocks yes but, not with any hose whipping. I wont run the volume flat out with them ever. I have beat a few fin fish out of them as well and, they came out nice and easy. I do wish they would add some steel to them though, while it would make it much more difficult to clear, it would make them much safer.

not a fan,you have no control,if it plugs and fires ur just along for the ride,at least with a steel reducer u have a chance to catch it before it fires!

reducing hoses are also heavier and tougher to push than whichever size hose you choose to reduce down with a steel . ours rarely see any action

I have had lots of issues with ruducing hoses  but the worst are plugs and if you swing them to much it is like a cow farting that has the runs..... steel reducers and proper placing hoses is the only way I will do now

Guys, 

I'm not following why it's the hoses' fault here.  Seems to me that if a mix will not reduce & pump through 4", it's going to plug regardless of what 4" you are trying to put it through. 

The 5 to 4 Ruff Neck hoses have been approved to replace such things as velocity reducers (otherwise called wiggles or double 90's) on bridge deck pumping in places like NY & IL without any difficulties.  The 5 to 3 does an excellent job pumping ICF & it got rid of the deadly items I mentioned previously.

As far as not having any reinforcement, that's not correct either!  These hoses have steel reinforcement & are rated for a CPMA compliant 85 bar (1233PSI) WP.

I'm skeptical about the report that this product is in any way dangerous.  It's no more dangerous that any other product that is not used in it's proper application.

I think anyone that has any issues with manufactured products (toothbrush, comb, laxatives, etc.) should contact the manufacturer & express their concerns & at least get the facts straight about the products before speaking like an authority on the subject.

i have never used them and never will, punching concrete thru reducing rubber does not make sense, Todd you are in the hot seat, you have heard the people, align with them and abolish the use and production of reducing hoses, your the man, you can do it, may help to save a kids life one day!!!!

1233 psi the first time you use it, what about the 2nd, 3rd. 4th, 5th and 6th time, who is signing this one off, not you i bet

and besides that i have green teeth, no hair and i shit like a bear in the woods

AND I LIKE IT THAT WAY

Got some bad news for you, that hose rating as all of our product are CPMA Certified.  No other manufacturer of system has been audited & certified....nobody.

so are you saying that hose is perfect till the day it fails??????

Tom,

Now you know its safer to reduce in steel,yes you may still plug but not in a hose, you telling me that rubber will not swell and sometimes allow a plug to be shoved thru causing a whipping action ? and they helped on bridge deck and such ? 5-4 steel reducer been doing it for years,5-3 reducing 90 and a endless 3" hose for ICFs,doing it for years safely,all certified components used and done the rite way,my point is the old way wasnt broken,why try and fix it, you just added another safety issue on a jobsite we dont need.

so are you saying that hose is PERFECT till the day it fails??????

so are you saying that hose is PERFECT till the day it FAILS??????

after fully reading your post, I would say I have tried your product ,and my experience and knowledge in this industry is well known and your product IS A SAFETY HAZARD, you can spout out psi ratings and how your product is great,well its not,its a accident waiting to happen,I have ran the 5-4 and it is a ticking bomb, if theyre so great I have two locked up so no one can use them, your welcome to buy them back one has 75 yds thru it , the other maybe 20 yds,because before they go on one of these pumps I'll pump staight out the 5" 90.

hey pudg, don't offer them to me cause i will tell you to shove em up your brown hole, they are deadly.

it must become mandatory that reducers are a certain length and it must become mandatory that outrigger support should be X times load, irrelevant of the ground conditions, fail-safe maneuvers

 A reducing hose may be applicable in some situations. For instance, A company in an area that uses mostly five inch hose every day that doesn't have a pile of steal reducers laying around might want one for ICF/CMU/Blockfill & grout jobs. I do agree with Tom that they are safer than a double 90 or anything else attached to the end of a discharge/placing hose.

 The fact is pumps plug, plain & simple. Most of the time it's due to debris that's to big to make through the reducer. Putting the reduction directly in the hands of the hose man, and the fact that it's rubber vs. steel is what concerns me. Another concern is the excess back pressure a reducing hose may create. If one rubber hose creates the same friction and back pressure as three steel pipes, I can only imagine how much this increases using a rubber hose with a 2" reduction.    

I agree with TT to an extent, there maybe applications were they are useful,but I do believe it would be safer for anyone needing to reduce to do it in steel and away from the hoseman,this is my issue,there was a statement made about a plug and the reducer blowing the clamp off,just think enough pressure to blow a clamp letting loose while a hoseman is attached to a reduction hose,thats my reasoning,I have seen it firsthand,I have plugged thousands of time in 5-4,5-3,and on one hand I can count the times the problem made it thru the hose causing a whipping action,compared to running reduction hoses and it happens constantly,if I'm gonna plug I want to get it out not have the hose swell and the pump push it out.

Point of my statement is time and place for everything. I'll back up Tom here on a couple of things. #1 No one can say they have never plugged a 4" hose its going to happen. #2 nothing is perfect after you have run concrete through it including steel reducers or 4" hoses they all eventually wear out, as a matter of fact who here can't wait for their system to get worn out a little so it isn't so damn heavy.  And I'll damn near bet the farm that no one has gone to the owner and said replace my lay down line and give me the heavyist pipe in the yard.  I understand your concerns on the whipping and perhaps someone should look into whipping accidents to see if reducing hoses were a factor in those accidents. If you choose not to use them thats fine but please do not use bully tactics totry to influence people in this industry before all the facts are in.  In the meantime mine is still being used day after day and no it's not perfect anymore.

and I'm not trying to bully anyone I feel as though in our region this is a deadly tool and we choose not to use it,my concern is for the hoseman that has no idea its a reduction hose and the dangers that go along with it, warning labels "this hose may whip at anytime due to reduction in hose".

I have a 5-3 reducing hose. Use it everyday and love it. Yes you have to be careful if the concrete flow stops stop the pump and shake it out safely. Life has gotten much easier since I bought it two years ago. I used to have to take off two reducers and a hose on every job to clean out because I suck sponges. 90% of all my jobs are residential though. 20-50 yards max. I pump slow. I wouldn't probably use it on course mud large pour.

see thats my point,its like the mudsnake,there are special applications that they may be useful,but does that make it safe ? on low volume pours, slow pours, but when a pump is delivered brand new with this on it it tells me they are saying its the hose to use everyday,and down here they are not safe to run on high output booms of today.And I would rather pull 2 reducers off and clean them everyday for the rest of my life than I would see a hoseman injured just one time,just my opinion.

Sorry pudg I wasn't implying you were using bully tactics.  The member asking Todd to start a campaign to have them abolished because of his personal preferences is who I was aiming for.  You were not the target I need to get my sights fixed. I agree totally with your asessment, there is a time and place for everything.  Once again I apologise if I offended you.

Cool. never seen those before in europe. But I can imagine quite quick that this is the most dangerous thing you can hang on the end of your boom. Really not well thought about.

Sorry but if you can't see why your hose is bad and your actually proud of it... I think people can't trust any of your opinions or products.
