Alrighty, here's my first report.
The hose's flexibility is absolutely excellent. I have a 90 degree angle made with it going into my pump. The angle is as short as a barb fitting, and it has absolutely no kink in it.
The stuff is more difficult to put on barbs than a regular tubing, ie smooth PVC, Tygon, vinyl. This is, I believe, due to the ribs. If its tougher to kink, than naturally its going to be tougher to flare. This isnt really a big problem, just a little more time consuming.
The problem that has arisen is this: it is hard to get a clamp to seal the hose. With the smooth PVC that I had been using, I was using a squeeze clamp, that clamped evenly around the entire clamp, and maintained a consistent circle.
However, this ribbed PVC has a larger outside diameter (OD). Ths inside diameter (ID) is of course the same 1/2 inch. Therefore, I was unable to use the hose clamps that I had previously been using. I bought some regular screw tightening hose clamps, which as most know do not clamp in an even circle. They tend to become oblong as they get smaller in diameter.
And that is currently the problem that Im trying to deal with.
I have gone through and used plumber's putty on all of my hose barbs. That has sealed all but two. The plumber's putty also made it easier to get the hose onto the barbs. But those two still have very slow little leaks. I may change out the clamps to newer, still round ones.
I did use a couple of those plastic ring clamps
these ones. I put them on the radiator barbs and they havent leaked at all. Im not sure if its the clamp, the barb type or just the fact that those barbs are facing downward. I may try to find some of those locally, and use them furthur.
Im posting this from a diiferent computer, so Ill check back to answer any questions from time to time. Im kind of in a hurry so I apologize if this post isnt very clear and easy to comprehend. And if anyone has knowledge of a different type of clamp, please post it, so I can check it out and see if it will work better.
Ill post back, when I figure it out, and post pics than too.
thx
