Question for those with experience w/ Oetiker clamps
I have a few questions for those that have worked with the Oetiker clamps.
1. Would they be sufficent for power steering, coolant, and oil lines?
2. Do they work with differnent hoses with slightly differnt diameter or do they need an exact hose type and size. I would hope that when crimped down it could replace a plethera of hose clamps?
3. Is there a style of oetiker clamps that would work best, as well as best type of pliers?
4. Is there another clamp system that would work better.
Thanks
Steve

Also, I am adding a new oil cooler, but I rather not remove the fittings around the oil filter that feed the cooler, one in particular, while the engine is in. So I cut the hose and plan to use a metal coupler to splice until I pull the engine again. I would to clamp the splice as well as the fittings on the bottom of the oil cooler.

Hey Steve
I just bought a pair of one of those pliers call Knipex 1099i
I bought the special pliers, even though I had a large pair of end nippers, because their special pliers allow you to clamp in tight spaces by using the side of the pliers
I was able to get it on eBay for around 26 bucks shipped..
I bought a few of the clamps and plan to replace the ones I removed
Like on the fuel vent line and the on three headed monster the runs on the top of the engine and the brake line to the brake fluid reservoir ....
Actually they are easy to remove ( I haven't put them on though yet...)
I read a write up on their website, that implies they are better than the typical hose clamps, but I can't vouch for that ...??
Here is a write up on one of the websites
Here is another tidbit
Here are some links

If you decide to go with these...They sell a bag of 10 for like 3 to 6 bucks on eBay... or do a search on Google
I would probably go with the stainless version unless you are planning on removing them shortly ...
All the best

Oetiker clamps maintain clamping force due to their ability to expand as a hose assembly is subjected to temperature cycling. Standard worm-drive clamps can't expand and, therefore, force the hose material to extrude away from the clamp area during a heat cycle. After several heat cycles, they can lose most of their clamping force.
The term "Stepless" relates to the absence of gaps or steps on the clamp's inner circumference.
The unique tongue-in-groove design provides uniform compression and a 360 degree seal.
Smooth-edged band steel prevents damage to hose, and the clamp is well-suited for flexible thin-walled hose.
The first half of the item numbers refer to each clamp's maximum outside diameter hose capacity, measured in millimeters.
The second half of the number refers to the width and thickness of the bans;
EXAMPLE;
505 is 5 mm wide and .05 mm thick
706 is 7 mm wide and .06 mm thick
The Dual Jaw Crimp Tool can be used either parallel to the hose or perpendicular to the hose allowing access in almost any situation.

2. They have different working diameters within a specific range. If you're looking for a bigger range, then look for "double pinch" type. They have an ear on either side of the clamp and each side will need to be "pinched" somewhat.
3. If you're using these on lines with any pressure behind them, I'd highly recommend using a gap-free style - either with a liner or tongue-and-groove. This style negates the "double pinch" style I mentioned in #2. As for pliers, find a pair of side-jaw installation pliers. My favorite are McMaster Carr part number 6541K69 ($27) which are made in Germany. These pliers not only have a jaw for crimping, they also have a jaw for removing (by cutting) the clamps. Makes both installation and removal easy. McMaster also has a wide assortment of Oetiker clamps.
4. Depends on your definition of better. I use Oetiker on some applications and worm-drive clamps for others. Some people like T-bolt, others like twin-wire, others like constant tension. It's really up to you. Oetiker also makes worm drive clamps, as do Gemi and Norma and I've had good luck with all of them.

I checked w/ a rep and he reccomended the Product group 163 which will go as small as 23.6 mm, which should work on most of the 5/8 and larger hoses. As far as the smaller ones like PS, I will doe something else, but this should take car of the majority of what I want.
I included as refernce sheet of sizes if anyone is interested, kind of a pain to get to on website. pgs 23-27 on downloaded catalog.

Which Oetiker clamp are you talking about? The company makes a pretty wide range of products: http://www.oetiker.com/content.asp?l=4&idNavig=7
May wish to check the tech data sheets for the clamp you're interested in: http://www.oetiker.com/content.asp?l=4&idNavig=520

OK, back to your OP. There is no one-clamp-fits-all solution for any part of your car. Worm drive or stepless screw clamps for the large diameter ducting/hoses or other lower pressure applications where the part needs routine service, ear clamps are best for higher pressure applications where routine disassembly of the hose is not necessary.
Give me the specific application, and we can find the correct clamp for it.
As far as Wiggins clamps. Best product out there, if you have an engine budget of $25K+. They are very expensive, and not at all easy to modify an existing system to. Full race application? Go for it. Anything street? No (IMHO).

This car is mostly street use, nothing fancy. I was looking to clean up some hoses with muliple clamps, or areas that won't need servicing regular.
I will take some photos tommarrow to show a few of the areas.

If you're going to replace any of the coolant or intake system clamps, my suggestion is the Oetiker Stepless Screw Clamps. You can buy from Aircraft Spruce, or check to see if your local hose supply company or Aeroquip dealer has them in stock.
