Grommet for 3/8 Adapter
For installation of DGT Nozzles on PVC distribution line. Drill schedule 40 PVC pipe with 7/16" drill bit having 60° taper. Place Mini-Adapter in drilled hole. Screw nozzles into Mini-Adapter until firm.
Work as described.
Drill the required hold, which I believe I had to look up on the site (no problem as it's listed) and the DGT nozzles just screw in. When they bottom out you're done. Really quick and really simple. Since they are rubber I can't speak to their longevity but it wouldn't be a big deal to screw out the DGT nozzle and set another one of these bushings in place. Unless you have a major operation. Possibly Phytomist would be a better solution, although these seem to be a little less work to get going. The others take adjustment.
I was a little skeptical at first but the bushings worked GREAT!!!
