Hose clamps
 

In looking for quality hose clamp a I stumbled upon these clamps made by Gates.

How do you think they would perform for the cylinder oil drain tubes an the oil breather?

They work great! I have used these in a water cooled application for a experimental a/c on the radiator due to space constraints and held extremely tight. I will use them on my plane for sure.

The video said they were tested to 200 degrees. Our air cooled cylinder temps can exceed 400 degrees. How will that affect the clamping pressure? Nice clean application though.
