Ernest,
Have you looked at the "Gates Power Grip" heat shrinkable hose
clamps as a backup with the push on hose ?
No. Nor do I wear a belt if I have suspenders.
The push-on hoses work by using a well understood, if not obvious, physical method. The harder you pull, the tighter it grips.
On the one hand, the manufacturer has tested their product and are confident enough to give it a 250psi rating. This being the real world, you've got to assume that they gave themselves some breathing room, but even barring that we have a safety factor of 2x to 3x above the pressures we're working with.
On the other hand, putting the clamp on the wrong spot on the hose will possibly interfere with how the clamping action of the hose was designed to work, and cause it to fail.
If you're going to use the push-on hose, use it as it was designed to work. I can't believe that the people making the hoses are complete morons and would sell a critical application specific product without any idea that it will work. If you find a need to second guess them, don't use their product to begin with.
I could be wrong, but that's the way I see it.
