Technical Cinch clamps

Can these type clamps be loosened up with
The tool?

 

Cut off wheel across…

 

Can the hose be saved, ie cut the top cinch.

 

Do you mean cutting the “hose” below where it was crimped?

 

That's a one use clamp. You can carefully cut it off and if the hose is still good replace it with the same or a different style clamp.

 

I have cut them with a good sharp set of side cutters where Johnny gee has marked it without disturbing the hose.

 

you can save the hose but those clamps get cut off. My daughter VW bus' fuel line had a bout 20 of them. Not anymore.

 

I have cut a few of those off over the years. What is the benefit of using them?

 

Lower manufacturing costs.

 

The clamp in the photo looks residential and RV plumbing as in PEX vs an automotive unit.

 

German engineering needs no benefit or motive. I had to replace the starter on that VW bus, one of the bolts went through the bell housing and had a nut on the other side that my daughter had to climb into the engine bay and hold while I laid on the ground with the ratchet. Reason? What's German for laughter?

 

You can also remove them by inserting a flat blade screwdriver into the open area just to the right of the red line and twisting. They come off in seconds. I like them because to my old eyes they look cleaner than a gear clamp and don't cut into the hose. Right name is oetiker.

 

lonewolf hit it on the head. They look cleaner. If they came in black it would be even better. Concealed to a point.

 

Germans make things complicated because they can.

 

Summit racing sells them. Not just for german junk or RVs.

 

Not only do they look cleaner, but from an installation perspective in mass production they're a lot simpler. Crimp the clamp, sides contact, and it's secure. For those of us installing them all by hand and worried about removal and maintenance, there are other options.
