Plastic will sometimes give un-expected results Max.
The area that split was not directly on the thread shaft. It was in an area where the stress from the taper focused, in the pump chamber itself. More people just plan stripped the threads. The plastic we used for this test was PPE, because of flow concerns. We re-designed using a two piece system with the volute chamber seperate. It is this extra peice that is used in retail Mag's.
Delrin is a great material, but it does not have good flow when used in injection molding with thin sections. We use Delrin in the pump volute insert where wall thickness is higher.
If everyone is really that concerned about Anolok in a small area, I will ask about the barb dates, and maybe bring back the plastic thread case for G 1/4 fittings only (no taper). I see there getting the WEB pages fitted, and the new ones are working well. I had email the store was back up, and the whole site maybe down for a day or two next week, well they switch over to a new server / host, as the DNS needs time to broadcast.
I am just glad not to do WEB work anymore
