I just received a few different sizes of these PVDF nozzles to try out this season. Anyone else using these or had used them. They are supposed to outlast the SS ones. I guess the downfall would be trying to keep them from dragging across the shingles and wearing them out. That shouldn't be to much of a problem though.
I bought some from Dultmeier last year. I have had no problems with them. They should last a long time. Only time will tell though.

They are KYNAR, and will last almost forever, or until you step on them, LOL Barry, how do you use them on a ball valve, where are the things they screw into ?
