Breeze Clamp Products

[cwsoules]

Some time ago someone posted a message suggesting that the Breeze Clamp constant torque clam might solve my problem with inner cooler hoses blowing off the turbocharger when I most need it. I have checked with their web site but could not find out any information on where to buy them.



Breeze Clamp seems to unclear as to why have an e-mail address on their web site. They accept questions but do not answer them.



Can alyone tell me where I can get one of their clamps in the San Francisco Bay Area? Or can you give me a phone number of a firm which sell this product line?

Did you start with local Cummins house?

The only nationwide auto parts store that may have a source is NAPA.

Outside of that I would check any farm equipment or industrial equipment store. I should hope one of them would have a supply considereing the number of turbocharged diesels in use.



Good luck

I found the clamps you described at a local industrial fitting/hose place, American Hose and Fitting. They had several different types/sizes in their store however, they would have to order in the specific clamp (i. e. , style and size) requested. So my suggestion is, check with your local industrial fitting/hose supply house.

I have found them locally here at Napa,Kenworth,and Ford.

If it doesn't work, this on their online store at http://www.airflo.com

Yes, it should help your hose to fitting problem. Silcone hose makers all specify a constant torque clamp. Breeze® is one of these manufacturer's clmaps that we use on silicone hoses. Cannot remember the other two, though.

Thanks

NAPA had them and I've replaced the clam,ps I was concerned about. Thanks for your help.

If the clamps you bought from NAPA are constant torque T-Bolt type clamps, your problem is solved. However, if they are worm drive type, you may still have a problem. I have worked with heavy truck and argiculture/construction equipment manufactures for several years on issues regarding IC connection problems.

Intercooler hose blow-off is a BIG deal to these guys. They don't want warrantee claims. The worm drive constant torque clamps were initially designed for coolant connections. These connections

do not see the pressures and temperatures that the IC system sees. They also do not use the silicone hoses utalized by the IC system. Although the Spring loaded T-Bolt is more expensive than the worm drive type, the engineers at the big rig manufactures know they are the solution to this problem.

If you can't find the spring loaded T-Bolt clamps{s) you need, let me know. I deal with an OEM distributor and I can get them for you. Alot cheaper than if you go to a dealer.

Breeze Clamps

The NAPA clamps I purchased looked just like the pictures of the constant torque clamps I downloaded from the internet sit of Breeze. I hope they are the same, I thought they were.



Should I tighten them as tight as I can? There were no instructions with the clamps. I have tightened thm as tight as I can, but have not yet towed a heavy load up a steep hill to see if the problem is solved.



Thanks

Hey Chuck

Ho w about posting some prices

 

[cwsoules]

Price

The clamps I bought from NAPA were their part number 705-1525 which were listed in the NAPA catalog at $3. 99 each.



They fit just fine and I hope they will solve my problem.

The clamps you purchased from NAPA are the worm drive type. These may work fine for you, especially if you are running under 20 PSI of boost. The installation torque on these is between 75-100 lbs. in. However, I have seen the band on these stretch and/or break under high boost and EGT's (The hard pull situation). I am going to try to attach a picture of a spring loaded t-bolt clamp. The bands on these are over 50% stronger than the worm drive. The thread pitch and diameter of the bolt also translate into about 5 times more clamping force per lb. in of torque vs. the worm screw. The spring compensates for expansion of the connection during load and for compression of the silicone rubber hose.



The clamps in the pictures are spares I bought when I replaced my IC clamps. With these, you don't need spares. Email me with your address and I'll give you the one you need (If you still want it. ) -- email address removed --

There are two different clamp sizes on the IC system. There are six smaller clamps and 2 large ones. The large one attaches the hose shown to the cooler unit on both the cooler inlet and outlet. The smaller ones are used on the rest of the system.

Thanks for the info. The picture you posted looks like the 3 inch clamps I purchased from NAPA. When I purchased them I compaired the pix I downloaded from the Breeze site with the one in the NAPA catalog and they looked alike. When delivered the actual clamps looked alike.



That being said I could still have not known of some differances between the clamps.



If I did get the wrong clamp I would love to take you up on your generous offer. My address is

Would there be any reason that a person could not just find some similar springs and install on our existing clamps to gain the constant torque quality?

 

[CGoyette]

remember not to overtighten these types of clamps MORE IS NOT BETTER IN THIS CASE.

Very helpful post, Turboclamp

I notice your truck is a 94.



Are the number and size of clamps the same for 2001. 5 trucks?



What are the torque recommendations?



Do you know what size silicone hose is needed to replace all of them?



I'm looking at silicone hose from www.bakerprecision.com but don't know what to order.



thanks for any help.

I'll send the clamp to you this weekend. Let me know when you get it.





The spring and hardware shown on the clamp in the pictures from my previous post CANNOT be used on the standard factory installed clamps. Here's why. This spring is designed to maintain a high tension through significant changes in connection diameter. This requirement resulted in the spring seen in the pictue. During vibration testing, it was determined that a band thickness of at least . 031" is needed to keep the band from breaking due to the fatigue caused by the mass of the spring on the bolt. The factory clamps are . 025" thick.



There is a lighter duty spring now avaliable that does work on the . 025" band. It does not meet the performance requirements of the heavy duty spring, but it is still better than none at all.

I believe DC is going to or has already started to use this smaller spring on some of the IC connections.



The price difference between the two spring clamps when I purchase them is about $1. 75. When there are only 8 on the whole system, I think the extra $14. 00 is worth while.



I don't know how much DC pays for these, but if you look at the total diesel trucks they sale, 8 clamps per truck, you can do the math a see why they use what they do.



I'll attach a photo to show the differences in hardware.

As far as I know, the size and number of clamps has been the same since 94. The samll spring may have been added on some(see my previous post).



Torque on these is 65-70lbs. in



I'll see what I can find out on the silicone hoses. The 45 degree

hoses on the intercooler may be hard to find.

CGoyette How tight is too tight?

The title says it all. I wondereded how to tell what was "tight enought".



Do you have your rig in Japan? Your tall truck would help in traffic, my VW bus was a help. Are you in Iwakuni, Yoko or Atsugi?
