(OEM) Single Use hose clamp

[Rattnalle]

That makes sense. I guess I should have clarified though that I mainly meant "for a joe sixpack working under his car", as I don't understand why you'd pick these over normal clamps that are cheaper, reusable, and don't require a special pair of pliers. Is it just for people who are obsessive about stock parts?

Beats me. I only use the normal ones myself.

Oetiker clamps are designed so that they are spring loaded. That is they will "breathe" along with expansion and contraction. In my experiment with Zip ties I'm betting on the elasticity of nylon to do the same.

As someone passing by this thread, what's the advantage of using these clamps vs the normal screw-tightening kind? These appear to be more expensive with no obvious benefit.

There's two types of screw (worm gear) clamps, the german ones are less prone to loosen with vibrations, while the hardware ones always loosen up. Imo, these may not stay tight enough, especially with temperature variation. Maybe the german one is safer but the problem here is playing with the rack - it's a bad and expensive job on this car.

and the 'german' ones - what Volvo uses in the engine bay - with bent holes.

Another reason, screw clamp dug in and ripped it.

More accurate is probably that overtightening damages stuff. You can break pretty much anything using a screw on clamp if you tighten it enough.

[Rattnalle]

I do agree the type with punched holes in the metal band cause more damage but the other kind is cheap enough that there's no reason to use the poor ones.

One (minor) thing I like about Oetiker clamps vs the worm screw type is that once they're tight they don't leave an excess "tail" hanging out to rake the back of your hand across.

Oetiker clamps are the only ones I’ve found that’s stop the power steering seep at the reservoir on either my P80 bastard and P2

I just added a quarter turn to the existing clamp and my leaks stopped

I’ll try that but a quarter turn in the clamp screw will work better.

Lashing out for getting me on the AC bearing......
