On many rubber hoses Porsche uses what I'll call (for lack of knowing the correct term) crimp type hose clamps. There are 2 of them shown in the picture. I need to take some of these hoses off. So the questions are:
1. What is the proper name for this type of hose clamp?
2. Are replacements available from any source besides a Porsche dealer?
3. What tool(s) are requred to properly open and crimp these clamps? (source?, price?)
4. Is is reasonable to just cut the old ones off and replace them with normal screw type hose clamps?

BTW, I have no doubt this has been covered before. But the downside of this great site is that there is so much material it is pretty tough for a newbie to isolate something specific. I did try the Search function, but that didn't help in this case.

You could use regular clamps, or fuel injection clamps which wouldn't cut the hose. Or you can use original. Those clamps you can actually get at Home Depot and the tool to crimp them. I used a lot of those clamps installing lawn sprinkler systems in high school.

as far as i know porsche is the only source for those

i just replace them with stainless steel screw type ones

as for searching the site, ALWAYS use more options - the basis search won't get you anywhere

OK, I did a little research. These are Oetiker 1-ear clamps. German company, of course. I called their US office who gave me a distributor in the Atlanta area. I thought I had it.

However, the distributor sells them in bags of 100! Since I don't intend to make a living at this, I guess I'll either get these from Porsche (and I suppose buy the assembly tool from Oetiker) or just go to screw type clamps.

Check out the plumbing section at Lowes or Home Depot. You will find them, they are commonly used for securing PVC pipe like in sprinkler systems.

Here is a pic of them, but you should be able to get them locally at a place that sells plumbing supplies. http://www.lawnsprinklerparts.com/shop/i...p?cPath=36

I went to the local Home Depot at lunch looking for these. No luck, but I can keep trying. Thanks for the help!

I would imagine that other German car manufacturers must have used similar hose clamps -- I found these via a Google searches:

http://www.evwparts.com/Merchant2/merchant...Code=HoseClamps

In addition to Porsche dealerships, BMW or VW dealerships might also be worthwhile asking.

Truechoice Motorsports sells them.
I use Wurth non perforated stainless clamps.
They are super heavy duty and don't cut hoses

I hate those crimp on clamps. The only way I can get them off is to cut them at the crimp. I was just replacing the line from the brake-fluid res to the clutch M/C and had a hell of a time getting the one off at the master. I ended up pulling the nipple out of the M/C and now I can't get it back in. It would have been easy if the stupid clamps were screw-tight type.

I dislike screw clamps and modern carmakers agree with me. The big problem they have is that if the hose shrinks over time the tension of the clamp is reduced. My fav claps are the ugly but reliable spring type, the kind that gouge up your arm when you are working on something else nearby. Crimp clamps are pretty good though and seem to work well.

If you do not feel like buying the crimper an end nipper type wire cutter can be made dull with a grinder, or if you only need to do a couple you can tape over the blades. $5 at harbor freight. They also sell a long reach diagonal cutter that I have used to crimp clamps that I could not otherwise reach.

I am on the lucky side and my Father has the crimp tool; It looks like a flat faced set of wire cutters.--$22

I have been able to get these from McMaster Carr in the past; there are some min qty items but most are not too bad.

I have used the "proper" crimper that is sold at Home Depot and I would highly recommend it over a "modified" wire cutter. The reason is because the crimper will crimp to the correct tension and then release, which will avoid the crimp being too tight or too loose! [img]style_emoticons/<#EMO_DIR#>/ohmy.gif[/img] From what I can remember, the crimper is about $80 bucks, but that would be cheap compared to a hose letting go or leaking because it was cut by too much pressure. A sharp wire cutter would be the proper tool to cut the "old" crimp off.

I have been in the import repair industry 40 years. The proper tool also has a post that presses into the top of the clamp's "ear" as it's being crimped to insure tension is correct. The statemant that a modified pair of cutters will not tension the clamp properly is correct
